System.Net.HttpWebRequest.Create(url) Problem

[RamonPV]

Hello:

I am trying to send an email which body will be a local aspx page, but when I try to get the page html using System.Net.HttpWebRequest.Create(url) I am getting this error:

Invalid URI: The format of the URI could not be determined

I read that I need to provide the full URI but I do not know how to do that so that it works when debuging(here I get a path like this http://localhost:43898/MyAppName/...) my application and also on the real server where the application is hosted(here I get a path like this: http://www.myDomain.com/...).

I am using ResolveUrl("~/Member/AppSubmitNotification.aspx") but i do not know how to provide the full path to avoid this error.

This is how i get my application root URL

public static string RootUrl()
    {
        return HttpContext.Current.Request.Url.AbsoluteUri.Substring(0, 
                  HttpContext.Current.Request.Url.AbsoluteUri.IndexOf(HttpContext.Current.Request.Url.AbsolutePath) + 1);
    }
 
public static string ApplicationRootUrl()
    {
        string root = RootUrl();
 
        if (root.Substring(root.Length - 1, 1) == "/" )
            root = root.Substring(0, root.Length - 1);
 
        root += HttpContext.Current.Request.ApplicationPath;
 
        if(root.Substring(root.Length - 1, 1) == "/" )
            root = root.Substring(0, root.Length - 1);
 
        return root;
    }
