c# 获取用户桌面选择的文件

引用COM组件 Shell32

Shell32.ShellFolderView desktopFolderView;
int hwnd;
Shell32.Shell iShell = new Shell32.Shell();
SHDocVw.ShellWindows iWindows = iShell.Windows();
SHDocVw.InternetExplorer iDesktop = iWindows.FindWindowSW(0, null, 8, out hwnd, 1);
desktopFolderView = (Shell32.ShellFolderView)iDesktop.Document;
List<string> list = new List<string>();
 
Shell32.FolderItems selItems = desktopFolderView.SelectedItems();
foreach (Shell32.FolderItem fitem in selItems)
{
 
    // if (fitem.IsFileSystem)
    //  listBox1.Items.Add(fitem.Path);
 
    list.Add(fitem.Name);
}
Title =""+ list.Count +"="+ list[0];

获取资源管理器里选择的文件：

引用COM组件Microsoft Internet Controls 和 microsoft shell controls and automation 就是 shell32.dll

string filename;
string ok = "";
ArrayList selected = new ArrayList();
foreach (SHDocVw.InternetExplorer window in new SHDocVw.ShellWindows())
{
    Debug.Print(window.LocationURL);
    filename = Path.GetFileNameWithoutExtension(window.FullName).ToLower();
 
    if (filename.ToLowerInvariant().Contains("desk"))
    {
        Debug.Print(window.LocationURL);
    }
     if (filename.ToLowerInvariant() == "explorer" || filename.ToLowerInvariant() == "资源管理器")
    {
        Shell32.FolderItems items = ((Shell32.IShellFolderViewDual2)window.Document).SelectedItems();
        var count = items.Count;
        foreach (Shell32.FolderItem item in items)
        {
            //selected.Add(item.Path);
            //MessageBox.Show(item.Path);
 
            ok= item.Path;   
 
        }
    }
}
