Byte array problem

[Josa]

Hi guys, i have a one byte array in c++ with /cli and return the next error:

error C2526: 'System::Collections::Generic::IList<T>:efault::get' : linking the C function can not return the class 'System::ArraySegment<T>' of C++

This is my code

	array<System::Byte>^ buffer = gcnew array<System::Byte>(1500);
	try
	{
		server->Receive(buffer);	
	}
	catch ( SocketException^ e ) 
	{
		Console::WriteLine( "{0} Error code: {1}.", e->Message, e->ErrorCode.ToString() );
		return ( e->ErrorCode );
	}

Sorry by the double post.

the error its in the line

server->Receive(buffer);

sorry for the 3° post, this is in the top code

#using <System.dll>
#using <mscorlib.dll>
using namespace System;
using namespace System::Text;
using namespace System::IO;
using namespace System::Net;
using namespace System::Net::Sockets;

I have clr enabled

SORRY FOR MY BAD ENGLISH

Looks like you translated back the error message from a non-English version of VC++. The MSDN page on the error message at http://msdn.microsoft.com/en-us/library/y59181c6.aspx doesn't quite tell me much more than that, but the original message is a bit more informative:

'identifier1' : C linkage function cannot return C++ class 'identifier2'

And though that is not the exact original meaning, in the context here the message probably means in essence that a native function can't return a managed type. This is speculation to some extent, though, since the code you posted doesn't really tell the whole story. Is, by any chance, perhaps server->Receive() a native function or is any other native function involved? Since the error message mentions C linkage, the function in question may not be a member of a class at all (or it may be static), and perhaps it's just unmanaged by mistake.
