C#winform中ListView及ContextMenuStrip的使用

1.新建一个Windows窗体应用程序

2.添加文件夹及图片资源

文件夹图片(folder.png)，文件图片(file.png)

3.在设计模式下添加控件

即：1个ListView(lvwData)、2个ImageList(imgLarge,imgSmall),1个ContextMenuStrip(cmsStyle)，如下所示：

4.设置各控件详细属性

2个ImageList(imgLarge,imgSmall)添加Images、设置ImageSize(imgLarge--32*32, imgSmall--16*16)，如下：

ContextMenuStrip(cmsStyle)添加Items，如下：

ListView(lvwData)要添加Items、Columns，绑定ContextMenuStrip(cmsStyle)、LargeImageList及SmallImageList

界面设计完成后，锁定所有控件，这是个好习惯~~

 5.为ContextMenuStrip(cmsStyle)的每个子项添加事件处理逻辑

  1 using System;
  2 using System.Collections.Generic;
  3 using System.ComponentModel;
  4 using System.Data;
  5 using System.Drawing;
  6 using System.Linq;
  7 using System.Text;
  8 using System.Windows.Forms;
