////////HTTPGET
 
          HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
          request.Method = "GET";
          request.ContentType = "text/html;charset=UTF-8";
          HttpWebResponse response = (HttpWebResponse)request.GetResponse();
          Stream myResponseStream = response.GetResponseStream();
          StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.UTF8);
          string retString = myStreamReader.ReadToEnd();
          myStreamReader.Close();
          myResponseStream.Close();

 

/////HTTPPOST
 
 1  public static string HttpPost(string Url, string postDataStr)

 4     request.Method = "POST";  
 5     request.ContentType = "application/x-www-form-urlencoded";

10     HttpWebResponse response = (HttpWebResponse)request.GetResponse();  
11     string encoding = response.ContentEncoding;  
12     if (encoding == null || encoding.Length < 1) {  
13         encoding = "UTF-8"; //默认编码  
14     }  
15     StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.GetEncoding(encoding));
