There is no overloaded method "OnMouseDown" with 0 parameters

Question

I am trying to set winform OnMouseDown event to a method I defined called SelectMouseDown.

The method is defined as follows:

method Maker.SelectMouseDown(Sender: Object; e: System.Windows.Forms.MouseEventArgs);

and I am trying to do the following:

OnMouseDown += System.Windows.Forms.MouseEventHandler(@Self.SelectMouseDown);

The compiler throws the following error message: "There is no overloaded method "OnMouseDown" with 0 parameters."

What am I doing wrong? How do you set events during runtime?

Thanks in advance,

You forgot new, and the event is named MouseDown as Marc Gravell pointed out:

MouseDown += new System.Windows.Forms.MouseEventHandler(@Self.SelectMouseDown);

I don't know about Delphi, but in C# the compiler can create the delegate automatically:

MouseDown += @Self.SelectMouseDown;
