简易文件管理器（C#）

效果如下：

将窗体 Form 的 Text 属性设置为“简易的文件管理器”。

窗体上添加 SplitContainer、TreeView、ListView 控件，设置属性。将 TreeView 控

件的 Dock 属性设置为 Left，ListView 控件的 Dock 属性设置为 Fill,MultiSelect 属性设置为False，View 属性设置为 List。

在 Form1.cs 中，添加对命名空间 using System.IO 的引用。

treeView放置在左边，ListView放置在右边

Form1.cs代码如下：

  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;
