推荐答案

在这里，看看:

Here, have a look: Creating Control Arrays in Visual Basic .NET and Visual C# .NET[^]

在代码中创建按钮时，添加描述事件处理程序，例如:

When you create the button in your code add describe the event handler, something like:

Button btn = new Button();
...
btn.Click += new EventHandler(commonEventHandlerMethodForAllButtons);

如果愿意，可以使用Tag属性添加有关按钮的信息，您可以在处理事件的方法中使用该按钮.例如:

If you like, you can use Tag property to add information about the button which you can use in the method handling the event. For an example:

enum Action {
    Some = 1,
    Other = 2
}
...
void SomeMethod() {
   Button btn = new Button();
   btn.Tag = Action.Some;
   btn.Click += new EventHandler(common_Click);
   ...
}
 
void common_Click(object sender, EventArgs e) {
   switch (((Action)(Button)sender).Tag) {
      case Action.Some:
         // do something
         break;
      case ...
   }
}
