Does C# have an equivalent of Delphi's message keyword?

Question

In delphi, I can create my own message like this,

const MY_MESSAGE = WM_USER+100;
procedure MyMessage(var Msg: TMessage); message MY_MESSAGE;

procedure TForm1.MyMessage(var Msg: TMessage);
begin
....
end;

bu in c# I can do that like this

public static uint ms;
protected override void WndProc(ref Message m)
{       
 if(m.Msg == ms) 
    MessageBox.Show("example");
    else
    base.WndProc(ref m);        
}

void Button1Click(object sender, EventArgs e)
{
    PostMessage(HWND_BROADCAST,ms,IntPtr.Zero,IntPtr.Zero);
}

but I don't want to override WndProc(), I want to create my own MyMessage() function, and when I post message it will run.

How can I do that? Thanks.

That's a special feature of Delphi of which there is no analogue in C#. In C# you need to override WndProc().
