#pragma comment(lib,"WS2_32.LIB")

WSADATA ws;
WSAStartup(MAKEWORD(2,0),&ws);

int res_socket, res, on;
struct sockaddr_in address;
struct in_addr in_ip;
res = res_socket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP);

WSACleanup();

可以这样获取网页源码(C#版)

WebClient wClient = new WebClient();
wClient.BaseAddress = txtName.Text;

wClient.Encoding = Encoding.UTF8;
wClient.Headers.Add("Content-Type","application/x-www-form-urlencoded");

Stream stream = wClient.OpenRead(txtName.Text); //txtName.Text为一个标准的http网址，例如：http://www.baidu.com

StreamReader Sr = new StreamReader(stream);

string str = string.Empty;

while ((str = Sr.ReadLine()) != null)
{
lsBox.Items.Add(str);
}

wClient.DownloadFile(txtName.Text,"hello.txt");
