When I was working with passing around anonymous types and trying to recast them I ultimately found it easier to write a wrapper that handled working with the object. Here is a link to a blog post about it.

Ultimately, your code would look something like this.

//create an anonymous type
var something = new {  
  name = "Mark",  
  age = 50  
};  
AnonymousType type = new AnonymousType(something);

//then access values by their property name and type
type.With((string name, int age) => {  
  Console.Write("{0} :: {1}", name, age);  
}); 

//or just single values
int value = type.Get("age");
