how to check if a given URL is HTTP or HTTPS in C#

Question

I need to check if a given URL (which is not necessarily prefixed with http or https) is HTTP or HTTPs.
Is this possible in C#?
If the user gives just www.dotnetperls.com without any prefix, I must be able to identify that it is an HTTP one. Tried the following,

 HttpWebRequest request = (HttpWebRequest)WebRequest.Create("www.dotnetpearls.com");         
 string u = request.RequestUri.Scheme;

But this gives an Invalid URL error. It expects the protocol to be specified.

try something like this:

public static bool IsHttps()
{
    return HttpContext.Current.Request.IsSecureConnection;
}

Or if you working with asp.net-web-api you can check if Request.RequestUri.Scheme is Uri.UriSchemeHttps.
