     else
     {
         //server = new epoll();

}

And then use the exported dll called D and C, C #
In addition to the D outside the
Other returns are wrong values​​, such as C #:

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate void OnConnectedCallBack(int id);

[UnmanagedFunctionPointer(CallingConvention.Cdecl)]
public delegate void OnReceivedCallBack(int sock, IntPtr pData, 
int len);

[DllImport("ShuNetTcp.dll",EntryPoint = "AddListenersss", CharSet 
= CharSet.Ansi, CallingConvention = CallingConvention.Cdecl)]
public static extern void AddListenersss(OnConnectedCallBack 
connectedCallback, OnReceivedCallBack readCallBack );

using:
m_onConnected = new NetServer.OnConnectedCallBack(OnConnected);
m_onReceived = new NetServer.OnReceivedCallBack(OnRead);
NetServer.AddListenersss( m_onConnected, m_onReceived );

call fun:
private void OnConnected(int id)
{
     Console.WriteLine ("连接完成 Id=>" + id.ToString());
}

private void OnRead(int id, IntPtr pdata, int len)
{
}

Received id and len are wrong! :(
Gurus to help me!!!!!!!!!!!!

Thank, Trass3r! Finally correct, why have to export these two?

You specified the C calling convention with UnmanagedFunctionPointer(CallingConvention.Cdecl), and extern(C) means use the C calling convention. Otherwise they'll be expecting a function using the D calling convention, which is incompatible.
