. NET implementation of Ping instance code _ Practical Tips

Copy Code code as follows:

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 service of the actual pinging
</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");

}
