Loading Unmanaged C++ in C#. Error Attempted to read or write protected memory
- by Thatoneguy
I have a C++ function that looks like this
__declspec(dllexport) int ___stdcall RegisterPerson(char const * const szName)
{
std::string copyName( szName );
// Assign name to a google protocol buffer object
// Psuedo code follows..
Protobuf::Person person;
person->set_name(copyName);
// Error Occurs here...
std::cerr << person->DebugString() << std::endl;
}
The corresponding C# code looks like this...
[DllImport(@"MyLibrary.dll", SetLastError = true)]
public static unsafe extern int RegisterPerson([MarshalAs(UnmanagedType.LPTStr)]string szName)
Not sure why this is not working. My C++ library is compiled as Multi Threaded DLL with MultiByte encoding.
Any help would be appreciated. I saw this is a common problem online but no answers lead me to a solution for my problem.
