Passing a Param to System.EventHandler in c#

Question

Since google has failed me for the past 5-10 minutes I have a quick question. I wish to pass a param value into a function that I call from a button.click Event Handler. The event is currently added using

MyButton.Click = new System.EventHandler(MyButton_click);

But I want the function to recieve:

private void MyButton_click(int ID)
{
...
}

How can I change my EventHandler declaration so that this can be accomplished?

Answer 1

Button.Click is defined as it is, and there is no way to change it. However,

myButton.Click += delegate { MyButton_click(1); }

will do the job.

Answer 2

您可以使用CommandArgument属性 ，然后将事件处理程序中的发送者强制转换为Button类型以获取CommandArgument值
