How to check domain availability.

Question

Recently, I have been assigned a task to create a simple web page what will help anybody to know the availability of the domain name that he/she wants to register.

I am on a .net platform using asp.net. For this task,I thought to use System.Net namespace and with the help of WebResponse and WebRequest classes I can come to know which domain is registered. But there I can come to know about only running website.

But what, if someone has registered his/er domain and not host any website yet. That could not be trace using this method.

I am looking for your valuable guidance or suggestions or any API that performs this task.

Thanks.

C#

public static string GetSubDomainID()
       {
           string domainID = HttpContext.Current.Request.Url.Host;
           if (domainID.Contains("/"))
               domainID = domainID.Substring(0, domainID.IndexOf("/"));
           if (domainID.ToLower().StartsWith("www."))//ignore www subdomain
               domainID = domainID.Substring(4);
           if (domainID.Contains("."))//Remove the last part i.e. organization e.g. .com / .net
               domainID = domainID.Substring(0, domainID.LastIndexOf("."));
           if (domainID.Contains("."))//Remove the second last part i.e. primary domain e.g. logisys
               domainID = domainID.Substring(0, domainID.LastIndexOf("."));
           if (domainID.Contains("."))//Get the first part
               domainID = domainID.Substring(0, domainID.IndexOf("."));
