Question

I have this:

<%foreach (var item in (List<MyClass>)ViewData["something"]) {%>

and it throws exception: Unable to cast object of type ‘<>f__AnonymousType01[System.Collections.Generic.List1[MyClass]]’ to type ‘System.Collections.Generic.List`1[MyClass]’.

ViewData[“something”] contains one myClass object with four elements. How to solve this?

var xx= (from x in be.x
                 select x).ToList();
ViewData["something"] = new { xx };

Answer 1

Your problem is that you are trying to cast an anonymous object with a property which is a list to a list.

To fix it, change from

var xx = (from x in be.x select x).ToList();
ViewData["something"] = new { xx };

to

var xx = (from x in be.x select x).ToList();
ViewData["something"] = xx;
