ho ottenuto un errore che i cant fix:"a" Non contiene una definizione di "b" e nessun metodo di estensione 'b' accettare un primo argomento di tipo
Error 1 'System.Windows.Forms.Label' does not contain a definition for 'Copy'
and no extension method 'Copy' accepting a first argument of
type'System.Windows.Forms.Label'
could be found (are you missing a using directive or an assembly reference?)
//path 156 22 FileWatcherEigen
Questo è stato il mio errore. Qualcuno può aiutarmi e spiegarmi cosa è andato storto?
Questo è il mio codice:

Si dice che il problema è all'interno di questa parte:
File.Copy(FileBrowseBox.Text, Path.Combine(DestinationBox.Text, Path.ChangeExtension(FileNameBox.Text, Path.GetExtension(FileBrowseBox.Text))));
ho cercato di trovare su questo forum, ma non ho potuto trovare la risposta o una soluzione
Esso funziona con questo codice:
using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
private bool cut = false;
private bool copy = false;
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
File.Copy(FileBrowseBox.Text, Path.Combine(DestinationBox.Text, Path.ChangeExtension(FileBox.Text, Path.GetExtension(FileBrowseBox.Text))));
label2.Text = "File Transfer Succeeded";
}
private void button2_Click(object sender, EventArgs e)
{
DialogResult resDialog = openFileDialog1.ShowDialog();
if (resDialog == DialogResult.OK)
{
FileBrowseBox.Text = openFileDialog1.FileName;
label2.Text = "";
}
}
private void button3_Click(object sender, EventArgs e)
{
DialogResult resDialog = folderBrowserDialog1.ShowDialog();
if (resDialog == DialogResult.OK)
{
DestinationBox.Text = folderBrowserDialog1.SelectedPath;
label2.Text = "";
}
}
private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
copy = true;
}
private void radioButton2_CheckedChanged(object sender, EventArgs e)
{
cut = true;
}
}
}
+1 mi ha battuto. –
@ p.s.w.g, grazie mille, ultimamente ho fatto +1 anche a molti dei tuoi per la stessa ragione. : D –
Ho ricevuto un'etichetta con il nome: "File" e ho cambiato il nome. Ma non ha funzionato. – Loko
