    IntPtr SonrakiClipboardOgesi; 

    public Form1() 
    { 
     InitializeComponent(); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     SonrakiClipboardOgesi = SetClipboardViewer(this.Handle); 
    } 

    protected override void WndProc(ref Message m) 
    { 
     int WM_DRAWCLIPBOARD = 0x0308; 
     int WM_CHANGECBCHAIN = 0x030D; 

     if (m.Msg == WM_DRAWCLIPBOARD) 
     { 
      ClipboardRead(); 
      SendMessage(SonrakiClipboardOgesi, m.Msg, m.WParam, m.LParam);

你所試圖做的是有點多餘的，因爲你並不需要，如果你有一個按鈕單擊事件收聽到剪貼板。 ..

if (Clipboard.ContainsFileDropList()) 
{ 
    // Get a list of files 
    System.Collections.Specialized.StringCollection returnList = Clipboard.GetFileDropList(); 
    // For each file in the list 
    foreach(string s in returnlist) 
    { 
     // split the file path and get the last node of the path which should be file.ext 
     String[] sa = s.Split('\'); 
     string sourceFile = s; 
     // set the file target 
     string targetFile = Environment.GetFolderPath(Environment.SpecialFolder.Desktop))+sa[sa.length-1]; 
     // Get a list of files 
     System.IO.File.Copy(sourceFile, destFile, true); // finally copy the file 
    } 
} 

您可能需要做一些調試，因爲我沒有Visual Studio h安迪和我沒有檢查，如果它編譯...

你已經問過這個問題，但我無法找到任何地方。 反正這裏是代碼如何從列表框中的文件複製到桌面：

foreach (string item in listBox1.Items) 
{ 
    FileInfo fileInfo = new FileInfo(item); 
    File.Copy(item,Path.Combine(
      Environment.GetFolderPath(Environment.SpecialFolder.Desktop), 
      fileInfo.Name), true); 
}
