Crea collegamento sul desktop C#

Question

Desidero creare un collegamento che punta a un file EXE, sul desktop, utilizzando .NET Framework 3.5 e facendo affidamento su un'API Windows ufficiale. Come lo posso fare?

Answer 1

collegamento URL

private void urlShortcutToDesktop(string linkName, string linkUrl) 
{ 
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); 

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url")) 
    { 
     writer.WriteLine("[InternetShortcut]"); 
     writer.WriteLine("URL=" + linkUrl); 
     writer.Flush(); 
    } 
} 

scorciatoia applicazione

private void appShortcutToDesktop(string linkName) 
{ 
    string deskDir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); 

    using (StreamWriter writer = new StreamWriter(deskDir + "\\" + linkName + ".url")) 
    { 
     string app = System.Reflection.Assembly.GetExecutingAssembly().Location; 
     writer.WriteLine("[InternetShortcut]"); 
     writer.WriteLine("URL=file:///" + app); 
     writer.WriteLine("IconIndex=0"); 
     string icon = app.Replace('\\', '/'); 
     writer.WriteLine("IconFile=" + icon); 
     writer.Flush(); 
    } 
}

se si desidera utilizzare alcune funzioni specifiche dell'API, si vorrà utilizzare lo IShellLink interface come come IPersistFile interface (tramite l'interoperabilità COM).

Here is an article that goes into detail what you need to do it, as well as sample code:

Answer 2

È possibile utilizzare questa classe ShellLink.cs per creare il collegamento.

Per ottenere la directory desktop, utilizzare:

var dir = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); 

o utilizzare Environment.SpecialFolder.CommonDesktopDirectory di creare per tutti gli utenti.

Con le opzioni aggiuntive come tasto di scelta rapida, descrizione ecc

In un primo momento, Progetto > Aggiungi riferimento > COM > Windows Script Host Object Model.

using IWshRuntimeLibrary; 

private void CreateShortcut() 
{ 
    object shDesktop = (object)"Desktop"; 
    WshShell shell = new WshShell(); 
    string shortcutAddress = (string)shell.SpecialFolders.Item(ref shDesktop) + @"\Notepad.lnk"; 
    IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(shortcutAddress); 
    shortcut.Description = "New shortcut for a Notepad"; 
    shortcut.Hotkey = "Ctrl+Shift+N"; 
    shortcut.TargetPath = Environment.GetFolderPath(Environment.SpecialFolders.System) + @"\notepad.exe"; 
    shortcut.Save(); 
} 

Answer 4

Usa ShellLink.cs a vbAccelerator per creare il collegamento con facilità!

private static void AddShortCut() 
{ 
using (ShellLink shortcut = new ShellLink()) 
{ 
    shortcut.Target = Application.ExecutablePath; 
    shortcut.WorkingDirectory = Path.GetDirectoryName(Application.ExecutablePath); 
    shortcut.Description = "My Shorcut"; 
    shortcut.DisplayMode = ShellLink.LinkDisplayMode.edmNormal; 
    shortcut.Save(SHORTCUT_FILEPATH); 
} 
} 

Answer 5

Senza ulteriore riferimento:

using System; 
using System.Runtime.InteropServices; 

public class Shortcut 
{ 

private static Type m_type = Type.GetTypeFromProgID("WScript.Shell"); 
private static object m_shell = Activator.CreateInstance(m_type); 

[ComImport, TypeLibType((short)0x1040), Guid("F935DC23-1CF0-11D0-ADB9-00C04FD58A0B")] 
private interface IWshShortcut 
{ 
    [DispId(0)] 
    string FullName { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0)] get; } 
    [DispId(0x3e8)] 
    string Arguments { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0x3e8)] get; [param: In, MarshalAs(UnmanagedType.BStr)] [DispId(0x3e8)] set; } 
    [DispId(0x3e9)] 
    string Description { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0x3e9)] get; [param: In, MarshalAs(UnmanagedType.BStr)] [DispId(0x3e9)] set; } 
    [DispId(0x3ea)] 
    string Hotkey { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0x3ea)] get; [param: In, MarshalAs(UnmanagedType.BStr)] [DispId(0x3ea)] set; } 
    [DispId(0x3eb)] 
    string IconLocation { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0x3eb)] get; [param: In, MarshalAs(UnmanagedType.BStr)] [DispId(0x3eb)] set; }

    [DispId(0x3ee)] 
    int WindowStyle { [DispId(0x3ee)] get; [param: In] [DispId(0x3ee)] set; } 
    [DispId(0x3ef)] 
    string WorkingDirectory { [return: MarshalAs(UnmanagedType.BStr)] [DispId(0x3ef)] get; [param: In, MarshalAs(UnmanagedType.BStr)] [DispId(0x3ef)] set; } 
    [TypeLibFunc((short)0x40), DispId(0x7d0)] 
    void Load([In, MarshalAs(UnmanagedType.BStr)] string PathLink); 
    [DispId(0x7d1)] 
    void Save(); 
} 

public static void Create(string fileName, string targetPath, string arguments, string workingDirectory, string description, string hotkey, string iconPath) 
{ 
    IWshShortcut shortcut = (IWshShortcut)m_type.InvokeMember("CreateShortcut", System.Reflection.BindingFlags.InvokeMethod, null, m_shell, new object[] { fileName }); 
    shortcut.Description = description; 
    shortcut.Hotkey = hotkey; 
    shortcut.TargetPath = targetPath; 
    shortcut.WorkingDirectory = workingDirectory; 
    shortcut.Arguments = arguments; 
    if (!string.IsNullOrEmpty(iconPath)) 
     shortcut.IconLocation = iconPath; 
    shortcut.Save(); 
} 
} 

per creare un collegamento sul desktop:

string lnkFileName = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Notepad.lnk"); 
    Shortcut.Create(lnkFileName, 
     System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "notepad.exe"), 
     null, null, "Open Notepad", "Ctrl+Shift+N", null);

Ecco un pezzo di codice che non ha dipendenza da un oggetto COM esterno (WSH), e supporta i programmi a 32 e 64 bit:

using System; 
using System.IO; 
using System.Runtime.InteropServices; 
using System.Runtime.InteropServices.ComTypes;

      // setup shortcut information 
      link.SetDescription("My Description"); 
      link.SetPath(@"c:\MyPath\MyProgram.exe"); 

      // save it 
      IPersistFile file = (IPersistFile)link; 
      string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory); 
      file.Save(Path.Combine(desktopPath, "MyLink.lnk"), false); 
     } 
    }

Answer 7

EDIT: Non consiglio più questa soluzione. Se non esiste ancora un metodo migliore rispetto all'utilizzo del motore di scripting di Windows, almeno utilizza la soluzione di @ Mehmet che chiama direttamente il motore piuttosto che creare uno script di testo in chiaro.

Abbiamo utilizzato VBScript per generare un collegamento. Non ha bisogno di p/Invoke, COM Interop e DLL aggiuntive.Funziona in questo modo:

• Generare un VBScript in fase di esecuzione con i parametri specificati del # metodo di CreateShortcut C
• Salva questo VBScript in un file temporaneo
• Attendere che lo script per finire
• Eliminare la temporanea File

Qui si va:

static string _scriptTempFilename; 

/// <summary> 
/// Creates a shortcut at the specified path with the given target and 
/// arguments. 
/// </summary> 
/// <param name="path">The path where the shortcut will be created. This should 
///  be a file with the LNK extension.</param> 
/// <param name="target">The target of the shortcut, e.g. the program or file 
///  or folder which will be opened.</param> 
/// <param name="arguments">The additional command line arguments passed to the 
///  target.</param> 
public static void CreateShortcut(string path, string target, string arguments) 
{ 
    // Check if link path ends with LNK or URL 
    string extension = Path.GetExtension(path).ToUpper(); 
    if (extension != ".LNK" && extension != ".URL") 
    { 
     throw new ArgumentException("The path of the shortcut must have the extension .lnk or .url."); 
    } 

    // Get temporary file name with correct extension 
    _scriptTempFilename = Path.GetTempFileName(); 
    File.Move(_scriptTempFilename, _scriptTempFilename += ".vbs"); 

    // Generate script and write it in the temporary file 
    File.WriteAllText(_scriptTempFilename, String.Format(@"Dim WSHShell 
Set WSHShell = WScript.CreateObject({0}WScript.Shell{0}) 
Dim Shortcut 
Set Shortcut = WSHShell.CreateShortcut({0}{1}{0}) 
Shortcut.TargetPath = {0}{2}{0} 
Shortcut.WorkingDirectory = {0}{3}{0} 
Shortcut.Arguments = {0}{4}{0} 
Shortcut.Save", 
     "\"", path, target, Path.GetDirectoryName(target), arguments), 
     Encoding.Unicode); 

    // Run the script and delete it after it has finished 
    Process process = new Process(); 
    process.StartInfo.FileName = _scriptTempFilename; 
    process.Start(); 
    process.WaitForExit(); 
    File.Delete(_scriptTempFilename); 
} 

Answer 8

Uso il riferimento "Modello oggetto host Windows Script" per creare un collegamento.

e di creare collegamento sul specifica posizione:

void CreateShortcut(string linkPath, string filename) 
    { 
     // Create shortcut dir if not exists 
     if (!Directory.Exists(linkPath)) 
      Directory.CreateDirectory(linkPath); 

     // shortcut file name 
     string linkName = Path.ChangeExtension(Path.GetFileName(filename), ".lnk"); 

     // COM object instance/props 
     IWshRuntimeLibrary.WshShell shell = new IWshRuntimeLibrary.WshShell(); 
     IWshRuntimeLibrary.IWshShortcut sc = (IWshRuntimeLibrary.IWshShortcut)shell.CreateShortcut(linkName); 
     sc.Description = "some desc"; 
     //shortcut.IconLocation = @"C:\..."; 
     sc.TargetPath = linkPath; 
     // save shortcut to target 
     sc.Save(); 
    }

io uso solo per la mia app:

using IWshRuntimeLibrary; // > Ref > COM > Windows Script Host Object 
... 
private static void CreateShortcut() 
    { 
     string link = Environment.GetFolderPath(Environment.SpecialFolder.Desktop) 
      + Path.DirectorySeparatorChar + Application.ProductName + ".lnk"; 
     var shell = new WshShell(); 
     var shortcut = shell.CreateShortcut(link) as IWshShortcut; 
     shortcut.TargetPath = Application.ExecutablePath; 
     shortcut.WorkingDirectory = Application.StartupPath; 
     //shortcut... 
     shortcut.Save(); 
    } 

Answer 11

suo È un metodo di estensione (testato), con commenti per aiutarti.

using IWshRuntimeLibrary; 
using System; 

namespace Extensions 
{ 
    public static class XShortCut 
    { 
     /// <summary> 
     /// Creates a shortcut in the startup folder from a exe as found in the current directory. 
     /// </summary> 
     /// <param name="exeName">The exe name e.g. test.exe as found in the current directory</param> 
     /// <param name="startIn">The shortcut's "Start In" folder</param> 
     /// <param name="description">The shortcut's description</param> 
     /// <returns>The folder path where created</returns> 
     public static string CreateShortCutInStartUpFolder(string exeName, string startIn, string description) 
     { 
      var startupFolderPath = Environment.SpecialFolder.Startup.GetFolderPath(); 
      var linkPath = startupFolderPath + @"\" + exeName + "-Shortcut.lnk"; 
      var targetPath = Environment.CurrentDirectory + @"\" + exeName; 
      XFile.Delete(linkPath); 
      Create(linkPath, targetPath, startIn, description); 
      return startupFolderPath; 
     } 

     /// <summary> 
     /// Create a shortcut 
     /// </summary> 
     /// <param name="fullPathToLink">the full path to the shortcut to be created</param> 
     /// <param name="fullPathToTargetExe">the full path to the exe to 'really execute'</param> 
     /// <param name="startIn">Start in this folder</param> 
     /// <param name="description">Description for the link</param> 
     public static void Create(string fullPathToLink, string fullPathToTargetExe, string startIn, string description) 
     { 
      var shell = new WshShell(); 
      var link = (IWshShortcut)shell.CreateShortcut(fullPathToLink); 
      link.IconLocation = fullPathToTargetExe; 
      link.TargetPath = fullPathToTargetExe; 
      link.Description = description; 
      link.WorkingDirectory = startIn; 
      link.Save(); 
     } 
    } 
} 

E un esempio di utilizzo:

XShortCut.CreateShortCutInStartUpFolder(THEEXENAME, 
    Environment.CurrentDirectory, 
    "Starts some executable in the current directory of application"); 

prima parm imposta il nome exe (che si trova nella directory corrente) 2 ° parm è la "Start In" cartella e 3 ° parm è la descrizione di scelta rapida.

La convenzione di denominazione del collegamento lascia alcuna ambiguità su ciò che farà. Per testare il collegamento basta fare doppio clic su di esso.

Nota finale: l'applicazione stessa (destinazione) deve avere associata un'immagine ICON. Il collegamento è facilmente in grado di individuare l'icona all'interno dell'exe. Se l'applicazione di destinazione ha più di un'icona, è possibile aprire le proprietà del collegamento e modificare l'icona in qualsiasi altra trovata nell'exe.
