WinForm 程序Post GEt web程序方法

  前段时间 做.net 程序要读取java的借口，但是选择了 java返回一个json串 然后.net程序加载时去读取 java的返回信息然后解析用来读取数据

  public static void PostDataByRifd()
        {
            try
            {
                System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.WebRequest.Create("www.baidu.com");

                byte[] requestBytes = Encoding.ASCII.GetBytes("");
                req.Method = "post";
                req.ContentType = "application/x-www-form-urlencoded";
                req.ContentLength = requestBytes.Length;

                Stream requestStream = req.GetRequestStream();
                requestStream.Write(requestBytes, 0, requestBytes.Length);
                requestStream.Close();
                System.Net.HttpWebResponse res = (System.Net.HttpWebResponse)req.GetResponse();
                StreamReader sr = new StreamReader(res.GetResponseStream(), Encoding.Default);
                string backstr = sr.ReadToEnd();            
                sr.Close();
                res.Close();

            

             

            }
            catch (Exception ex)
            {
                throw ex;
            }
        }
