Daten von C# an Delphi senden

[API]

Die Kernfrage ist, wie man diese beiden Konstrukte zueinander kompatibel macht:

Delphi-Quellcode:

type
  TMyStruct = packed record
    Number: integer;
    Msg: string[255];
  end;
  PMyStruct = ^TMyStruct;

Code:

    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)]
        internal struct MyStruct
        {
            public int Number;
            [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 256)]
            public string Message;
        }
