Delphi DLL in C#

[Tino]

Hi all,
I have a problem with loading the Delphi 7 dll in to my C# project! The dll delphi structure is as follows:

ShortString myfunction(shor tstring par1, shortstring par2, shortstring par1);

I read somwhere that C# represenatation of ShortString is byte array so I did the following:

[DllImport("xxyy yykg.dll", EntryPoint = "NewLic", CallingConventi on = CallingConventi on.StdCall, ExactSpelling =
true, CharSet = CharSet.Ansi)]

public static extern byte [] NewLic(byte[] par1, byte[] par2, byte[] par3);

byte [] output= NewLic(par1, par2, par3);


but I get thye following error message:

Cannot marshal 'return value': Invalid managed/unmanaged type combination.

Thanks in advance,
