我在C#中创建了一个拖放控件,允许人们将文件拖放到我的表单上.这是我遇到的问题,它在被调试时工作正常; 但是,当以管理员模式运行我的程序时,它不起作用.这有什么理由吗？

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; …
