Best way to filter domain objects for json output in an ASP.NET MVC application

Question

If I\'m rendering a regular view in asp.net mvc the only domain object properties that show up in my page the ones I specifically write out. For example:

<         


        

Answer 1

I use anonymous types for this:

var customer = from c in serviceLayer.GetCustomers()
               where c.Id == id.Value
               select new { FirstName = c.FirstName };

This is not just a good idea. Rather, it's protection against the exception that you will get when calling Json() if your object graph contains a circular reference.
