Posted By:Sasi Prabhu       Posted Date: July 30, 2011    Points: 40    Category: ASP.NET Controls    URL: http://www.dotnetspark.com  

Way to Extract the Domain Name the URL.
 


Using Inbuild .Uri Object - Host:

public static string ExtractDomainNameFromURL(string Url)

{
    if (!Url.Contains("://"))

        Url = "http://" + Url;
 
    return new Uri(Url).Host;

}



Using String Modifiers - Split:

public static string ExtractDomainName(string Url)

{
 if (Url.Contains(@"://")) Url = Url.Split(new string[] { "://" }, 2, StringSplitOptions.None)[1]; return Url.Split('/')[0]; }

Using Regular Expression :


public static string ExtractDomainName(string Url)
{
    return System.Text.RegularExpressions.Regex.Replace(Url,@"^([a-zA-Z]+:\/\/)?([^\/]+)\/.*?$", "$2");
}
