C#通过POST发送数据函数，类似asp中的xmlhttp

1 //purl处理页面,str参数（如：username=admin&passwod=123456）
2
3 //返回处理页面输出的内容
4
5 //使用：string data = PostData(http://www.soaspx.com/, "action=Fav&str=这个是好网站");
6
7        public static string PostData(string purl,string str)
8         {
9             try
10             {
11                 byte[] data = System.Text.Encoding.GetEncoding("GB2312").GetBytes(str);
12                 // 准备请求
13                 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(purl);
14
15                 //设置超时
16                 req.Timeout = 30000;
17                 req.Method = "Post";
18                 req.ContentType = "application/x-www-form-urlencoded";
19                 req.ContentLength = data.Length;
20                 Stream stream = req.GetRequestStream();
21                 // 发送数据
22                 stream.Write(data, 0, data.Length);
23                 stream.Close();
24
25                 HttpWebResponse rep = (HttpWebResponse)req.GetResponse();
26                 Stream receiveStream = rep.GetResponseStream();
27                 Encoding encode = System.Text.Encoding.GetEncoding("GB2312");
28                 // Pipes the str
