Using the generic type 'System.Collections.Generic.List<T>' requires 1 type arguments

Solution
The `List<T>` class is a generic type.
In order to use it, you need to provide a type argument.
For example, if you want to have a list of integers, you need to declare it as `List<int>`, not `List`.
Problem
What does it mean? I used a list of list in ASP.NET MVC and sent them through `ViewData` of `ActionResuls` to retrieve it in views. However, when I change it to list of list, it gives me an error of `HttpWebException`. When I check it inside the immediate window, it tells me that the error is: Using the generic type 'System.Collections.Generic.List<T>' requires 1 type arguments So, what does it mean and what did I do wrong using it?
