I have a com delphi exe, with this code:

TMyRecord = Record
  a:Integer;
end;

function RecordToVariant(r: TMyRecord):OleVariant;
var
  P:Pointer;
begin
  result :=VarArrayCreate([0, sizeof(TMyRecord)], varByte);

  P := VarArrayLock(result);
  Move(P^, result, sizeof(r));
  VarArrayUnlock(result);
end;


so  i use this code in 1 function like

procedure SomeFunction(var v:OleVariant);
var
  myRecord:TMyRecord;
begin
  myRecord.a := 1;
  v := RecordToVariant(myRecord);
end;

Ok my problem is i can't change this code. In my c# consuming client
I've to use SomeFunction geting this olevariant like object but i dont
know how to extract this record to another c# struct with the same
members.

Anybody can help me?????
