C#怎么动态添加MenuStrip的菜单

你可以先在设计器里手动添加，然后在Designer.cs里找到相应代码剪切过来就行，如下

private System.Windows.Forms.MenuStrip menuStrip1;
private System.Windows.Forms.ToolStripMenuItem aAAToolStripMenuItem;
private System.Windows.Forms.ToolStripMenuItem bBBToolStripMenuItem;
private void button1_Click(object sender, EventArgs e)
{
this.menuStrip1 = new System.Windows.Forms.MenuStrip();
this.aAAToolStripMenuItem = new System.Windows.Forms.ToolStripMenuItem();
this.bBBToolStripMenuItem = new System.Windows.Forms.ToolStripMenuItem();
//
// menuStrip1
//
this.menuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.aAAToolStripMenuItem});
this.menuStrip1.Location = new System.Drawing.Point(0, 0);
this.menuStrip1.Name = "menuStrip1";
this.menuStrip1.Size
