c# 点鼠标左键显示contextmenu菜单，点右键不显示

Question

我给你一个思路吧，在你所点击的控件的鼠标点击事件中将右键菜单和控件进行绑定，而不要在开始时绑定private void Form1_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                this.ContextMenuStrip = contextMenuStrip1;
                this.contextMenuStrip1.Show();
                this.contextMenuStrip1.Top = this.Location.Y +  e.Y;
                this.contextMenuStrip1.Left = this.Location.X + e.X;
            }
            else
                this.ContextMenuStrip = null;
        }

Answer 1

contextMenuStrip1是你右键菜单控件，this.ContextMenuStrip是窗口的右键菜单属性

Answer 2

有一个技术含量不高的方法啊.
在控件右侧显示属性的地方,找到ContextMenuStrip,然后选你的contextMenuStrip1

Answer 3

        private void pictureBox6_MouseClick(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left)
            {
                pictureBox6.ContextMenuStrip = contextMenuStrip2;
                contextMenuStrip2.Show(Control.MousePosition);
            }            pictureBox6.ContextMenuStrip = null;
        }
