Issue with Late binding in asp.net mvc

Question

I am doing something of the sort:

return View("XXXXXX", new
        {
            Message = "ok"
        });

However when trying to read the variable via Model.Message an exception is thrown:

'object' does not contain a definition for 'Message'

Even though hovering on Model in the debugger shows Message = "ok"

Any Idea why this might be happening ?

Your problem might be because you're sending an anonymous type, which is getting translated into an object. — Corey Adler, Feb 11 '13 at 15:26

You would have to specify dynamic as the model type; however, I had issues with that and resorted to using a strongly-typed model. — Brian Mains, Feb 11 '13 at 15:33
@IronMan84 and AliRıza Adıyahşi well yes thought so ... so the answer is "don't use anonymous types as Models" ? I find it odd especially since the debugger can see the variable and its value — Jonny, Feb 11 '13 at 15:34

As was mentioned in the comments, the trouble you're running into is that you're trying to use an anonymous type to pass through to the view. This means it will show up in your debugger, but your page will blow up, since it will interpret it as an object and not the type you're trying for.

The best solution for it would be to create a new Model class that has the Message property in it and to strongly type your View to that Model.
