initializeComponent还真脆弱

我在Form1.Designer.cs中添加了匿名委托

    this.btnEvent.Click += new System.EventHandler(this.MyEventClick);//a event of mine
    this.btnEvent.Click += new System.EventHandler(delegate(object sender, EventArgs e)
            {
                MessageBox.Show("I have no name", "AnonymousMethodOfbtnEvent", MessageBoxButtons.OKCancel);
            });
结果报告了下面的错误：

“The designer cannot process the code at line 90:（这里是我上面的代码）
The code within the method 'InitializeComponent' is generated by the designer and should not be manually modified.Please remove any changes and try opening the designer again.”
意思是“设计器无法处理第90行的代码:（这里是我上面的代码）。方法“initializeComponent”内的代码由设计器生成，不应手动修改。请移除任何更改，然后尝试重新打开设计器”。
所以我只好移往Form1.cs:         
    public Form1()
    {
        InitializeComponent();
        btnEvent.Click += new System.EventHandler(delegate(object sender, EventArgs e)
        {
            MessageBox.Show("I have no name", "AnonymousMethodOfbtnEvent", MessageBoxButtons.OKCancel);
        });
    }

不过它说得吓人--“请移除任何更改，”，结果我加行中规中矩的代码，也没问题：

this.btnEvent.Click += new System.EventHandler(this.MyEventClick);//a event of mine
