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

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);
}
