关于动态创建控件数组

Question

我写一个程序,程序里会动态创建 RadioButton 及 CheckBox ,我利用集合的方式实现的.现在动态创建没有问题,我在集合中加了一个Click的事件函数,测试成功了.但是我需要是在引用这个集合的窗体中能够处理这个集合的事件.请高手指点,一下是部分代码:using System;

        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(new SerialPortConf());
        }
    }

这个是创建控件集合的代码

        {
            MessageBox.Show(sender.ToString());
        }      
    } //end class SerialPortConf
   
}上面粗体的地方是不正确的,系统提示是:ClickHandle是个方法组,无法给他赋值.
我该如何让写一个方法能够把集合中的所有控件的 click消息通过一个函数来解决,因为我每个创建的控件都增加了 tag标记,所以在处理时可以区分到底是谁.关键不知道该怎样实现?
谢谢!!!

Answer 2

XXXX 具体控件=new XXXX()
具体控件=this.ralist[i]
再给具体控件加事件
