C#网络连接 socket支持post,get之类http协议（chunked，gzip），同时支持webservice协议。
熟练掌握之后web qq的协议就很简单了，本人已经做了一个完整的webqq协议。如果以下有问题的话，请发我qq邮箱:[email protected]
class Program
{
static void Main(string[] args)
{
//httpNetHelper net = new httpNetHelper();
//Console.WriteLine(net.CreatePostString("http://127.0.0.1:8080/smshttp",
// "act=getbalance&unitid=826&username=DGHK&passwd=123456"));
Console.WriteLine("********WebService Testing!*******");
HttpHelper http = new HttpHelper();
Dictionary<string, string> dics = new Dictionary<string, string>();
dics.Add("byProvinceName", "江苏");
http.NameSpace = "http://WebXml.com.cn/";
http.WEncoding = Encoding.UTF8;
Console.WriteLine(http.GetWebServiceStr("http://www.webxml.com.cn/WebServices/WeatherWebService.asmx",
"getSupportCity", dics));
Console.WriteLine("*********Get Testing!***********");
http.WEncoding = Encoding.UTF8;
http.IniStalling();
Console.WriteLine(http.MethodGetHttpStr("http://127.*.*.*:8080/smshttp?act=getbalance&unitid=826&username=DGHK&passwd=123456"));
Console.WriteLine("*********Post Testing!**********");
http.WEncoding = Encoding.UTF8;
http.IniStalling();
Console.WriteLine(http.MethodPostHttpStr("http://127.*.*.*:8080/smshttp?act=getbalance&unitid=826&username=DGHK&passwd=123456",""));
Console.ReadLine();
}
}
第一种写法：
internal class httpNetHelper
{
public string CreateGetString(string geturl)
{
return GetHtml(geturl, null);
}
public string CreatePostString(string posturl, string date)
{
return GetHtml(posturl, Encoding.UTF8.GetBytes(date));
}

private String accept = "*/*";
public String contentType = "application/x-www-form-urlencoded; charset=UTF-8";
/// <summary>

internal string GetHtml(string url, byte[] data = null)
{
using (var response = GetResponse(url, data))
{
using (var stream = response.GetResponseStream())
{
using (var sr = new StreamReader(stream, Encoding.UTF8))

}
