选择文件夹的对话框！

    public class FolderDialog : FolderNameEditor
    {
        FolderNameEditor.FolderBrowser fDialog = new System.Windows.Forms.Design.FolderNameEditor.FolderBrowser();
        public FolderDialog()
        {
        }
        public DialogResult DisplayDialog()
        {
            return DisplayDialog("请选择一个文件夹");
        }
        
        public DialogResult DisplayDialog(string description)
        {
            fDialog.Description = description;
            return fDialog.ShowDialog();
        }
        public string Path
        {
            get
            {
                return fDialog.DirectoryPath;
            }
        }
        
        ~FolderDialog()
        {
            fDialog.Dispose();
        }
    }

使用：
            FolderDialog openFolder = new FolderDialog();
            openFolder.DisplayDialog();

唉，真是千辛万苦才找到阿！连Shell API都用上了！最后终于让我看到了它！哈哈,爽
