Answer 1

//用ContextMenu实现public partial class Form1 : Form
    {
        private System.Windows.Forms.ContextMenu contextMenu_treeview;
        private System.Windows.Forms.MenuItem menuItem_save;
        private System.Windows.Forms.MenuItem menuItem_exit;
        private System.Windows.Forms.MenuItem menuItem_add;        public Form1()
        {
            InitializeComponent();            //生成treeview快捷菜单
            this.menuItem_save= new System.Windows.Forms.MenuItem("save", onSave);
            //onSave为save的click事件,后面添加的方法相同
            this.menuItem_exit= new System.Windows.Forms.MenuItem("exit");
            this.menuItem_add= new System.Windows.Forms.MenuItem("add");
            this.contextMenu_treeview = new System.Windows.Forms.ContextMenu();
            this.contextMenu_treeview.MenuItems.AddRange(new System.Windows.Forms.MenuItem[]{
               menuItem_save,menuItem_exit,menuItem_add});            //假定你说的Control控件为treeView1
            this.treeView1.ContextMenu = this.contextMenu_treeview;
         }            public void onSave(object sender, EventArgs e)
         {
              //为事件添加代码
         }
}就这样
