How to find base url from dll in c #?

Question

From the DLL that is called by the C # .NET web application, how do you find the base URL of the web application?

Answer 1

Will this work?

HttpContext.Current.Request.Url

UPDATE:

To get the base url you can use:

HttpContext.Current.Request.Url.GetComponents(UriComponents.SchemeAndServer, UriFormat.Unescaped)

Answer 2

If this is an assembly that non-web projects can reference, you may not need the System.Web namespace.

I would use the DannySmurf method.

HttpContext.Current.Request.Url.GetComponents(UriComponents.HostAndPort, UriFormat.Unescaped);

Answer 4

Assembly.GetExecutingAssembly(), DLL.

    {
        _baseURL += ":" + HttpContext.Current.Request.Url.Port;
    }
}
