Errore XML ben formato durante il salvataggio della web part condivisa tramite Web 2.0

Question

Ho creato una web part personalizzata con una proprietà di raccolta personalizzata (schede). La web part funziona correttamente quando si modifica e si salva la proprietà personalizzata in modalità modifica (tramite browser). Voglio aggiornare la mia parte web personalizzato utilizzando i servizi web, quindi ho esportato la parte web e preso il contenuto XML e superato così com'è (così ho potuto facilmente verificare), ma è verificato un errore

The file you imported is not valid. 
Verify that the file is a Web Part description file (*.webpart or *.dwp) and that it contains well-formed XML. 

I hanno già convalidato l'XML utilizzando validatore xml on-line e rimosso questa dichiarazione

<?xml version="1.0" encoding="utf-16"?> 

come questo è quello che causa l'XML non ben Formex secondo il validatore XML, ma ancora fortuna, lo stesso errore.

Qualsiasi idea? Non sono riuscito a capire cosa c'è di sbagliato nell'XML, specialmente nella proprietà Tabs.

Codice:

string webPartXml = string.Empty; 
    string pageUrl = currenturl; 

     Guid storageKey = new Guid(webpartid); 

     using (StreamReader sr = new StreamReader(@"C:\tab.txt")) 
     {    
      webPartXml = sr.ReadToEnd();     
     } 
     webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 

     try 
     { 
      svc.SaveWebPart2(pageUrl, storageKey, webPartXml, WebpartpagesSvc.Storage.Shared, false); 
     }catch(Exception err) 
     { 
      throw; 
     }

Penso che sia quando si tenta di ripristinare il xml originale questo lo spezza. Hai davvero bisogno di questa riga di codice:

webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 

Cosa succede se lo rimuovi? Se non funziona, consiglio avvolgendo il valore nel CDATA-tag al fine di sfuggire alla xml:

string startTabProperty = @"<property name=""Tabs"" type=""Test.Tabs, Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c9e6068352095bx6"">"; 
string endTabProperty = "></property>"; //Note the >< in order to identify correct place 
webPartXml = webPartXml.Replace("&lt;", "<").Replace("&gt;",">"); 
webPartXml = webPartXml.Replace(startTabProperty, startTabProperty + "<![CDATA["); 
webPartXml = webPartXml.Replace(endTabProperty , ">" + "]]>" + "</property>"); 

Buona fortuna!

scrivere il codice di seguito nella Element.xml & cambiamento solo il tuo nome della lista del modulo in listUrl & TitleUrl

<Module> 
<File>
