Chapter 19 page 702

Hi, I have finished the chapter but had to go back to the first exercise of this chapter because of an error I cant seem to shake off,

In the exercise on page 702 it instructs you to insert the following code:

Code:

    public static string FromAddress
    {
        get
        {
            string result = WebConfigurationManager.AppSettings.Get("FromAddress");
            if (!string.IsNullOrEmpty(result))
            {
                return result;
            }
        }
        throw new Exception("AppSettings FromAddress not found in web.config file.");
    }

But I am getting errors for both "get" and "throw". For "get" it says 'AppConfiguration.FromAddress.get': not all code paths return a value and for "throw" it says "a get or set accessor expected".

I have inserted the using.System.Web.Configuration; to the top of the code.

Any help would be appreciated,

Nick

Hi Nick,

Your throw statement is outside the curly brace of the getter, while it should be inside. That should fix both problems as a) the throw statement is now in a valid location, and b) the getter returns something (or throws an error) on all code paths.

Cheers,

Wow! Can't believe I missed that one,

Thanks again Imar,

Looks like you found the Global class? ;-)

Haha yep!

Was something I remember reading through the other day and thought "what is that?" so I thought I'd ask, but then realised when I was looking through my Solution Explorer that I had the Global.asax file sat right in front of me so tried to delete the post!

I noticed. But I get notifications by e-mail, so I saw your question before you deleted it.... ;-)
