non virtual class methods

A non-virtual Delphi class method is translated to a C# static method.

type

  TBase = class(TObject)

  public

    class function ClassMethod(X: Integer): Integer;

  end;

class function TBase.ClassMethod(X: Integer): Integer;

begin

  Result := X;

end;

Generated C#:

public class TBase : TObject

{

    public static int ClassMethod(int X)

    {

        int result;

        result = X;

        return result;

    }

}

In Delphi, a class method can be called through the class type:

I := TBase.ClassMethod(0);

It can also be called through an object reference:

PBase := TBase.Create;

I := PBase.ClassMethod(0);

In C#, static methods are called through the class name. Therefore both calls are translated to a static C# call:

I = TBase.ClassMethod(0);

Even if the Delphi source calls the method through an object reference, the generated C# code calls the static method through the declaring class.

This is correct for non-virtual class methods, because their dispatch is not polymorphic.
