--------------------编程问答-------------------- 你好我需要判断是的mms://music.outboundmusic.com/OMRadioJazz 这种格式的链接是否连接正常
而不是楼上说的http://www.163.com/index.html 链接 --------------------编程问答-------------------- string url = "http://www.baidu.com/";
try
            {
                HttpWebRequest request;
                HttpWebResponse response;
                string strResult = "";
                request = (HttpWebRequest)HttpWebRequest.Create(url);
                request.Timeout = _iSetTimeOut;
                request.KeepAlive = false;
                request.ServicePoint.Expect100Continue = false;
                request.ServicePoint.UseNagleAlgorithm = false;
                request.ReadWriteTimeout = _iSetTimeOut;
                request.Method = "GET";
                request.Accept = "image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/msword, */*";
                request.UserAgent = " Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50727;)";
                response = (HttpWebResponse)request.GetResponse();
                if (response.StatusCode == HttpStatusCode.OK)
                {
                    return true;
                }
            }
            catch (Exception ex) { return false; }
--------------------编程问答-------------------- 楼上的朋友我要的不是判断http://www.baidu.com/是判断mms://music.outboundmusic.com/OMRadioJazz格式的链接 http可以判断 --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- --------------------编程问答-------------------- 唉,无比纠结啊,你把他的地址换了试试不就行了
