C#listview+上下⽂菜单（⿏标右键菜单）ContextMenuStrip
1 从⼯具栏中添加⼀个ContextMenuStrip到设计界⾯，编辑ContextMenuStrip项（在此我只举删除的例⼦）
2 添加ListView的MouseUp事件，代码如下
private void listView1_MouseUp(object sender, MouseEventArgs e){
if (e.Button == MouseButtons.Right){
listView1.ContextMenuStrip = null;if (listView1.SelectedItems.Count > 0){
contextMenuStrip1.Show(listView1, new Point(e.X, e.Y));}}}
new Point(e.X,e.Y)得到的是⿏标所在位置坐标
3 为ContextMenuStrip的删除项添加Click事件，代码如下
private void删除ToolStripMenuItem_Click(object sender, EventArgs e){
listView1.Items.RemoveAt(listView1.SelectedItems[0].Index);}
如此即可实现⿏标右键删除，很简单吧^-^
