C ++ WinSock2错误

Question

昨天我尝试用C ++创建一个套接字服务器，但是编译时出错了。 错误：

错误6错误LNK2019：函数“public：static unsigned long __cdecl Env :: GetSocket（void）”中引用了未解析的外部符号_ imp _socket @ 12（？GetSocket @ Env @@ SAKXZ） C：\ Users \ JoshuaTha \ Documents \ Visual Studio 2010 \ Projects \ HabboV5 \ HabboV5 \ Network.obj HabboV5

我的主要.cpp类：

// HabboV5.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
#include "Env.h"

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
cout.write("hi", 2);
cout << "Hello World!" << endl;

Env::Network = new Network();
Env::Network->Start();

while (1)
{
    char input[256];
    cin.getline(input, 256);
}
}

Network.h：

#pragma once
#include <WinSock2.h>

class Network
{
private:
    SOCKET socket;
public:
    Network(void);
    void Start();
};

Network.cpp：

#include "StdAfx.h"
#include "Network.h"
#include <WinSock2.h>
#include "Env.h"

Network::Network(void)
{
}

void Network::Start()
{
    this->socket = Env::GetSocket();

    SOCKADDR_IN sInformation;

    sInformation.sin_family = AF_INET;
    sInformation.sin_addr.s_addr = INADDR_ANY;
    sInformation.sin_port = htons(30000);

    bind(this->socket, (SOCKADDR*) (&sInformation), sizeof(sInformation));
    listen(this->socket, 10);
}

Env.h：

#include "stdafx.h"
#include "Network.h"
#include <WinSock2.h>

class Env
{
public:
    static Network* Network;

    static DWORD GetSocket()
    {
        return socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);
    }
};

在链接器选项中（在项目上单击鼠标右键，链接器，输入），您需要将wsock32.lib或ws2_32.lib添加到输入文件列表中。
