.NET Forum / .NET Framework / Interop / June 2006MFC CString in C#
As my earlier post would suggest, I am using some C++ unmanaged DLLs in a C# program. A number of the functions used in the C++ DLL have CString as a parameter. I cannot seem to figure out the correct way to expose the CString objects to the C# DLL call. I was able to get parameters passed using char* and LPCTSTR. I know I could convert all of the CStrings to LPCTSTR but it would be best if I did not have to make many changes to the existing C++ code. I am trying to keep all of the conversions as close to the DLL interface or C# as possible. There is not support for this in the current implementation. You could write a custom marshaler that handles this case. Marcus > As my earlier post would suggest, I am using some C++ unmanaged DLLs in > a C# program.

Are you trying to pass a CString to a C++ function, or get one back as a return value? > As my earlier post would suggest, I am using some C++ unmanaged DLLs in > a C# program.
