Get base URL of an ASP.NET MVC Application

Hello everyone, I am going to share the code sample to get the base URL using ASP.Net MVC and the code detail as given below.

Please see the example and put your thoughts and comment as well.

public class ApplicationConfig

{

        public static string GetBaseUrlByKey(string key)

        {

            if (key == Constants.baseURL)

            {

                return GetBaseUrl();

            }

        }

        public static string GetBaseUrl()

        {

            var requestURL = HttpContext.Current.Request;

            var appDomainUrl = HttpRuntime.AppDomainAppVirtualPath;

            if (!string.IsNullOrWhiteSpace(appDomainUrl)) appDomainUrl += "/";

            var baseURL = string.Format("{0}://{1}{2}", requestURL.Url.Scheme, requestURL.Url.Authority, appDomainUrl);

            return baseURL;

        }

 }

Thank you!
