c#调用C++ DLL

Question

我有几个C++的 dll 也有源码，只是我对VC不享，请问一下大家，c#中要如何调用这c++的DLL?

Answer 1

C++ DLL放到Debug文件夹
BOOL __stdcall ConnectToDataSever(char *IP, short port, unsigned short SysCode, unsigned short TerminalNo);对应C#声明[DllImport("UniClientInterface.dll")]
public extern static bool ConnectToDataSever(string IP, int port,int SysCode,int TerminalNo);

Answer 2

类似        [DllImport("User32.dll", CharSet = CharSet.Auto, EntryPoint = "SendMessage")]
        static extern IntPtr SendMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

Answer 3

[DllImport(".dll")]
public static extern int MethodName(param ...);
