Question

如何在Visual Studio 2008中使用Windows套接字2.我使用预编译的标头，到目前为止我尝试的是：

在 StdAfx.h 文件中包含 winsock2.h
并输入 WS2_32.LIB 作为项目设置中的附加依赖项

我收到这些错误

顺便说一句，如果我在 main.cpp （我的main（）函数所在的位置）中包含 winsock2.h ，那么我会得到不同的错误

以下是 StdAfx.h 标题文件的内容

#pragma once

#include <stdio.h>
#include <tchar.h>
#include <windows.h>
#include <winsock2.h>

Answer 1

你的in_addr问题是由于事实上in_addr中没有S_addr字段引起的。有一个in_addr.s_addr可以重定向到in_addr.S_un.S_addr。

Answer 2

从内存中我认为windows.h包含winsock.h（即套接字v1），它与winsock2.h冲突。您可以通过定义WIN32_LEAN_AND_MEAN：

来防止这种情况发生

#include <stdio.h>
#include <tchar.h>
#define WIN32_LEAN_AND_MEAN
#include <windows.h>
#include <winsock2.h>

Answer 3

您需要在windows.h之前包含winsock2.h
