Go How can I get my WebApp ' s base URL in ASP.

This article transferred from: HTTP://STACKOVERFLOW.COM/QUESTIONS/1288046/HOW-CAN-I-GET-MY-WEBAPPS-BASE-URL-IN-ASP-NET-MVC

Maybe it is extension or modification of the answers posted this but I use simply following and it works:

Request.Url.GetLeftPart(UriPartial.Authority) + Url.Content("~")

When my path is:http://host/iis_foldername/controller/action

Then I receive:http://host/iis_foldername/

public string GetBaseUrl()
{
    var request = HttpContext.Current.Request;
    var appUrl = HttpRuntime.AppDomainAppVirtualPath;

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

    var baseUrl = string.Format("{0}://{1}{2}", request.Url.Scheme, request.Url.Authority, appUrl);

    return baseUrl;
}

That's really depends on what often you need to use it ... if this is a, single, deal then just put it in the class where yo U need this data,

If you anticipate using it in multiple classes in your app, then I use a folder called Helpers in the base of my app,

I have a static class called and Statics I put functions like the above there ...

Just make sure-the above from to public string GetBaseUrl()public static string GetBaseUrl()
