c# - 拖放在 C# 中不起作用

Question

我在 C# 中创建了一个拖放控件，以允许人们将文件拖放到我的表单上。这是我遇到的问题，它在调试时工作正常；但是，在管理员模式下运行我的程序时，它不起作用。这有什么原因吗？

这是我的代码:

private void panel1_DragEnter(object sender, DragEventArgs e)
{
    if (e.Data.GetDataPresent(DataFormats.FileDrop)) 
        e.Effect = DragDropEffects.Copy;
    else
        e.Effect = DragDropEffects.None;
}

string startDir;

private void panel1_DragDrop(object sender, DragEventArgs e)
{
    string[] files = (string[])e.Data.GetData(DataFormats.FileDrop);
    dropZoneLabel.Text = "Adding files; please wait...";
    foreach (string file in files)
    {
        bool isFolder = File.GetAttributes(file).HasFlag(FileAttributes.Directory);
        if (isFolder)
        {
            //Scan the folder for all files
            DirectoryOperations searchFolders = new DirectoryOperations();
            DirectoryInfo di = new DirectoryInfo(file);
            foreach (FileInfo dropfile in searchFolders.FullDirList(di, "*"))
            {
                listBox1.Items.Add(dropfile.Name);
            }
            startDir = di.FullName;
        }
        else
        {
            //It's a file so add it as normal
            listBox1.Items.Add(file);
        }
    }
    dropZoneLabel.Text = "Drop files or folders here";
}

从 Windows Vista 开始，由于用户界面特权隔离，您无法从以较低完整性级别运行的应用程序拖放到以较高完整性级别运行的应用程序。
