我们来看下在C#中如何用post数据的，请下面的这个例子。

//purl处理页面,str参数（如：username=admin&passwod=123456）
//使用：string data = PostData("http://www.hecks.tk/", "action=Fav&str=这个是好网站");

public static string PostData(string purl,string str)
         {
             try
             {
                 byte[] data = System.Text.Encoding.GetEncoding("GB2312").GetBytes(str);
                 // 准备请求
                 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(purl);

//设置超时
                 req.Timeout = 30000;
                 req.Method = "Post";
                 req.ContentType = "application/x-www-form-urlencoded";
                 req.ContentLength = data.Length;
                 Stream stream = req.GetRequestStream();
                 // 发送数据
                 stream.Write(data, 0, data.Length);
                 stream.Close();

HttpWebResponse rep = (HttpWebResponse)req.GetResponse();
                 Stream receiveStream = rep.GetResponseStream();
                 Encoding encode = System.Text.Encoding.GetEncoding("GB2312");
                 // Pipes the stream to a higher level stream reader with the required encoding format.
                 StreamReader readStream = new StreamReader(receiveStream, encode);

Char[] read = new Char[256];
                 int count = readStream.Read(read, 0, 256);
                 StringBuilder sb = new StringBuilder("");
                 while (count > 0)
                 {
                     String readstr = new String(read, 0, count);
                     sb.Append(readstr);
                     count = readStream.Read(read, 0, 256);
                 }

rep.Close();
                 readStream.Close();

return sb.ToString();

}
             catch (Exception ex)
             {
                 return "";
                // ForumExceptions.Log(ex);
             }
         }
