Why does the callback method of an EventHandler<T> need to be static?

[TMattC]

Could someone please explain to me why the callback method of an EventHandler has to be static? According to the .NET documentation the delegate looks like this:

[SerializableAttribute]
public delegate void EventHandler(
Object sender,
TEventArgs e
)

No hint of static there. So, my second question would be; If I want to declare a delegate which should take a static callback method, how to do that?

What makes you think that the method needs to be static? :confused:

public class Foo
{
public event EventHandler MyEvent;

public void Test()
{
    var handler = MyEvent;
    if (handler != null) handler(this, EventArgs.Empty);
}

}

public class Bar
{
private readonly Foo _foo;

public Bar()
{
    \_foo = new Foo();
    \_foo.MyEvent += MyEventHandler;
}

public void Test()
{
    \_foo.Test();
}

private void MyEventHandler(object sender, EventArgs e)
{
    // Not static!
    Console.WriteLine("Bacon.");
}

}

Well, Im not sure... I tried to use the EventHandler earlier, got error, and was under the impression that the non-static nature of the callback-method was the cause. So I changed the code declaring an explicit delegate and it worked. But now when I changed back it actually still works. So Im a little confused right now why it didnt work earlier. Anyway. I can clearly see it works with a non-static method now. Just forget I asked :-\ Thanks anyway.

Some statical analysis may flag it as "requires static" if you do not reference any non-static members of the class.
