C#上下文菜单(右键菜单)ContextMenuStrip用法总结

设置窗体的ContextMenuStrip属性或者也可以在按钮单击事件里调出：

private void button_Click(object sender, EventArgs e)

{

    Button btn = sender as Button;

    btn.FlatAppearance.BorderSize = 0;

    Point point = new Point(btn.Left + this.Left + 5, btn.Top + this.Top + 40);

    contextMenuStrip.Show(point);

}

/// <summary>

/// 绑定右键菜单

/// </summary>

private void BindMenu()

{

    ToolStripMenuItem menu0 = GetMenuItem("一级1", imageList1.Images[0]);

    ToolStripMenuItem menu01 = GetMenuItem("二级11", imageList1.Images[1]);

    menu01.Click += new EventHandler(toolStripMenuItem_Click);//添加事件

    ToolStripMenuItem menu02 = GetMenuItem("二级12", imageList1.Images[2]);

    menu0.DropDownItems.Add(menu01);

    menu0.DropDownItems.Add(menu02);

    cMenu.Items.Add(menu0);

    ToolStripMenuItem menu1 = GetMenuItem("一级2", imageList1.Images[0]);

    ToolStripMenuItem menu11 = GetMenuItem("二级21", imageList1.Images[1]);

    ToolStripMenuItem menu12 = GetMenuItem("二级22", imageList1.Images[2]);

    menu1.DropDownItems.Add(menu11);

    menu1.DropDownItems.Add(menu12);

    cMenu.Items.Add(menu1);

}

/// <summary>

/// 菜单项事件响应

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

private void toolStripMenuItem_Click(object sender, EventArgs e)

{

    ToolStripMenuItem menu = sender as ToolStripMenuItem;

    MessageBox.Show(menu.Text);

}

/// <summary>

/// 生成菜单项

/// </summary>

/// <param name="txt"></param>

/// <param name="img"></param>

/// <returns></returns>

private ToolStripMenuItem GetMenuItem(string txt,Image img)

{

    ToolStripMenuItem menuItem = new ToolStripMenuItem();

    menuItem.Text = txt;

    menuItem.Image = img;

    return menuItem;

}
