使用线程加载指定目录下的所有子目录和文件名称到TreeView中

界面设计：

从工具箱中拖放一个TreeView(teeView1)和一个Button(button1)到WinForm窗体中

添加引用：

using System.Threading;
using System.IO;

详细代码：

#region 目录树委托定义
private delegate void UpdateTreeViewDelegate(TreeNode node);//声明委托类型
private static string CurrentFolderPath;
#endregion

#region 目录树节点操作函数
