Question

Let’s say I have some form where user input some WCF/RIA Services URL and he wants to save it and be sure that URL will work.

(The main condition is that it could be any WCF/RIA Services URL.)

How to parse it correctly to make sure that this WCF/RIA Services URL is valid?

Which the best strategy is?

Thanks!

Use the code below to get back a status response to make sure that the URL is valid:

var request = WebRequest.Create(serviceUrl) as HttpWebRequest;
            if (request != null)
            {
                request.ContentType = "application/xml";
                request.Method = "GET";
            }
var response = request.GetResponse() as HttpWebResponse;
            if(response.StatusCode == HttpStatusCode.OK)
            {
                 //valid url, continue to persist.
            }
            else
            {
                 //invalid url throw your exception or show message.
            }
