C＃：ShortCut and Impersonation

Question

我在創建服務器上的快捷方式時遇到問題。它總是拋出異常：

訪問被拒絕。 0x80070005

我真的不知道問題是否發生，因爲快捷方式的位置或快捷方式的目標。我不得不使用模擬來訪問文件系統。使用IO.File和IO.Directory我可以創建導演，複製和刪除文件等......沒有任何問題。另外，如果我使用模擬用戶打開文件存儲庫的遠程桌面，則可以創建具有任何問題的快捷方式。

但是，爲了創建一個快捷方式，我使用WHSell，並且它似乎有一些模擬問題。有任何想法嗎？

這是我的代碼：

作爲一種變通方法，您可以禁用模擬，然後使用shell臨時目錄中創建快捷方式文件。然後，您可以將該文件作爲字節數組傳遞給模擬的代碼，並將其保存到正確的路徑。

public void CreateShortCut(string shorcutPath, string shortcutTarget) 
{ 
    byte[] bytes = null; 

    // Disable impersonation 
    using (System.Security.Principal.WindowsImpersonationContext ctx = System.Security.Principal.WindowsIdentity.Impersonate(IntPtr.Zero)) 
    { 
     // Get a temp file name (the shell commands won't work without .lnk extension) 
     var path = Path.GetTempPath(); 
     string temp = Path.Combine(Path.GetTempPath(), Guid.NewGuid().ToString() + ".lnk"); 
     try 
     { 
      WshShell shell = new WshShell(); 
      IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(temp); 
      shortcut.TargetPath = shortcutTarget; 
      shortcut.Save(); 
      bytes = System.IO.File.ReadAllBytes(temp); 
     } 
     finally 
     { 
      if (System.IO.File.Exists(temp)) System.IO.File.Delete(temp); 
     } 
    } 

    // Impersonation resumed 
    System.IO.File.WriteAllBytes(shorcutPath, bytes); 
}
