.net实现ping的实例代码

class ServicePinger
    {
        private static readonly ILog log=LogManager.GetLogger(typeof(ServicePinger));
        public ServicePinger(string siteName, string siteUrl, string serviceUrl)
        {
            if (siteName==null)
                throw new ArgumentException("siteName can't be null");

            if (siteUrl==null)
                throw new ArgumentException("siteUrl can't be null");

            if (serviceUrl==null)
                throw new ArgumentException("serviceUrl can't be null");

            if (siteName.Length==0)
                throw new ArgumentException("siteName can't be empty");

            if (siteUrl.Length==0)
                throw new ArgumentException("siteUrl can't be empty");

            if (serviceUrl.Length==0)
                throw new ArgumentException("serviceUrl can't be empty");

            pingingSiteName=siteName;
            pingingSiteUrl=siteUrl;
            serviceUrlToPing=serviceUrl;

 

        }

        private string pingingSiteName=string.Empty;
        private string pingingSiteUrl=string.Empty;
        private string serviceUrlToPing=string.Empty;
        private int timeoutInMilliseconds=3000;

 
        /// <summary>
        /// Does the actual pinging of the service
        /// </summary>
        public void Ping()
        {
            try
            {
                HttpWebRequest request=(HttpWebRequest)WebRequest.Create(serviceUrlToPing);
                request.Method="POST";
                request.ContentType="text/xml";
                request.Timeout=timeoutInMilliseconds;
                request.Credentials=CredentialCache.DefaultNetworkCredentials;

 
                Stream stream=(Stream)request.GetRequestStream();
                using (XmlTextWriter writer=new XmlTextWriter(stream, Encoding.ASCII))
                {
                    writer.WriteStartDocument();
                    writer.WriteStartElement("methodCall");
                    writer.WriteElementString("methodName", "weblogUpdates.ping");
                    writer.WriteStartElement("params");
                    writer.WriteStartElement("param");

                    writer.WriteEndElement();
                    writer.WriteEndElement();
                }

 
                request.GetResponse();
            }
            catch (InvalidOperationException ex)
            {
                log.Error(ex);
            }
            catch (NotSupportedException ex)
            {
                log.Error(ex);
            }

        }
