HttpWebRequest的使用方法

需要在WinForm里调用一个url发送短信，为了防止自己忘记，特将HttpWebRequest的使用方法摘录如下：

 

 

 1        public void SendSms(string phoneNumber, string text)
 2        {
 3            string url;
 4            url = string.Format(@"http://a.b.c.d/path/?user=username&password=password&phonenumber={0}&text={1}&charset=gb2312", phoneNumber, HttpUtility.UrlEncode(text));
 5
 6            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
 7
 8            request.MaximumResponseHeadersLength = 10240;
 9            request.Credentials = CredentialCache.DefaultCredentials;
            request.Method = "GET";
            request.Timeout = 60000;
            WebResponse webRep = request.GetResponse();

            Debug.WriteLine(webRep.Headers.ToString());
            Debug.WriteLine(webRep.ResponseUri.OriginalString);

            读取网页内容/不需要#region 读取网页内容/不需要
            // Obtain a 'Stream' object associated with the response object.
            Stream ReceiveStream = webRep.GetResponseStream();

            Encoding encode = System.Text.Encoding.GetEncoding("gb2312");

            // Pipe the stream to a higher level stream reader with the required encoding format. 
            StreamReader readStream = new StreamReader(ReceiveStream, encode);
            Console.WriteLine("\nResponse stream received");
            Char[] read = new Char[256];

            // Read 256 charcters at a time.    
            int count = readStream.Read(read, 0, 256);
            Console.WriteLine("HTML\r\n");

            while (count > 0) {
                // Dump the 256 characters on a string and display the string onto the console.
                String str = new String(read, 0, count);
                Console.Write(str);
                count = readStream.Read(read, 0, 256);
            }

            Console.WriteLine("");
            // Release the resources of stream object.
            readStream.Close();
            #endregion

            // Release the resources of response object.
            webRep.Close();

        }
