SharePoint Dragons

The next bit was taken from a forum post and written by Wayne Fan:

It’s a piece of code that issues a HTTP request and can be used for determining the version of SharePoint on a server. We’re documenting it here, because we know there’ll come a day that we’ll need this code:

HttpWebRequest request =(HttpWebRequest)WebRequest.Create(“http://<servername>/default.aspx&#8221;);

request.Credentials=new NetworkCredential(“<username>”,”<password>”,”<domain>”);

HttpWebResponse response =(HttpWebResponse)request.GetResponse();

request.Accept = “text/plain”;

Console.WriteLine(“Server Version:{0}”,response.GetResponseHeader(“MicrosoftSharePointTeamServices”));

When it’s a SharePoint 2010 site, you will get the result is like this: MicrosoftSharePointTeamServices: 14.0.0.6106

And in SharePoint 2007 site, the result is like this: MicrosoftSharePointTeamServices:12.0.0.4518
