Can you extend HttpContext.Current.User.Identity properties

Question

Is there a way to override HttpContext.Current.User.Identity to add another property (screen name)?

My application uses Identity and I've left the unique identity as email. I store user data such as first / last name in a separate "Profile" table. Is there a way to store this information somewhere within HttpContext.Current?

It doesn't necessarily need to be within User. I have had a search and noticed there's a HttpContext.Current.ProfileBase. Not sure how to use it though - and I really don't want all the excess stuff that base comes with.

You can put value in HttpContext.Current.Items. It is dictionary which lifetime is single request.

You can use it like this:

public static string CurrentScreenName
{
    get
    {
        string screenName = (string)HttpContext.Current.Items["CurrentScreenName"];

        if (string.NullOrEmpty(screenName))
        {
             screenName = ResolveScreenName();
             HttpContext.Current.Items["CurrentScreenName"] = screenName;
        }
        return screenName;
    }
}

It will execute ResolveScreenName() only once for single request.

Also you can make extension method to access screen name from IIdentity

public static class Extensions
{
    public static string GetScreenName(this IIdentity identity)
    {
        return CurrentScreenName;
    }
}

And then use it like this:

string screenName = HttpContext.Current.User.Identity.GetScreenName();
