C# winform treeview node添加右键菜单并选中节点

首先，要向窗体添加一个TreeView控件；

然后再添加一个ContextMenuStrip控件；

接下就要给TreeView添加一个MouseDown事件，代码如下：

 

 private void treeView1_MouseDown(object sender, MouseEventArgs e)       

  {           

  if (e.Button == MouseButtons.Right)//判断你点的是不是右键           

  {                 Point ClickPoint = new Point(e.X, e.Y);              

   TreeNode CurrentNode = treeView1.GetNodeAt(ClickPoint);            

     if (CurrentNode != null)//判断你点的是不是一个节点               

   {                  

   switch (CurrentNode.Name)//根据不同节点显示不同的右键菜单，当然你可以让它显示一样的菜单    

                {                       

case "treenode0":                             CurrentNode.ContextMenuStrip = contextMenuStrip1;            

                 break;                        default:                             CurrentNode.ContextMenuStrip = contextMenuStrip2;                             break;                     }                     treeView1.SelectedNode = CurrentNode;//选中这个节点                 }             }         }
