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

        public MainForm()
        {
            InitializeComponent();

            this.大图标ToolStripMenuItem.Click += new System.EventHandler(this.ToolStripMenuItem_Click);
            this.详细信息ToolStripMenuItem.Click += new System.EventHandler(this.ToolStripMenuItem_Click);

            this.小图标ToolStripMenuItem.Click += new System.EventHandler(this.ToolStripMenuItem_Click);
            this.列表ToolStripMenuItem.Click += new System.EventHandler(this.ToolStripMenuItem_Click);
        }

        #region 鼠标右键勾选事件处理

            {
                return;//已经选中则返回
            }
            else
            {

        {
            ToolStripMenuItem tsMenumItemTemp;
            for (int i = 0; i < cms.Items.Count; i++)
            {
                if (!(cms.Items[i] is ToolStripMenuItem))
                {
                    continue;
                }
                tsMenumItemTemp = cms.Items[i] as ToolStripMenuItem;
                if (tsMenumItemTemp.Checked)
                {
                    tsMenumItemTemp.Checked = false;
                }
            }
        }

        /// <summary>
        /// 设置ListView列表显示样式

        {

            {
                if (name == "详细信息")
                {
                    lvi.ImageIndex = 1;
                }

                }
            }
            switch (name)
            {
                case "大图标":
                    listData.View = View.LargeIcon;
                    break;
                case "详细信息":
                    listData.View = View.Details;
                    break;
                case "小图标":
                    listData.View = View.SmallIcon;
                    break;
                case "列表":
                    listData.View = View.List;
                    break;
                case "平铺":
                    listData.View = View.Tile;
                    break;
            }
        }
        #endregion
    }
}

6.运行效果如下所示：
