How do I create a dynamic type List

Question

I don\'t want my List to be of fixed type. Rather I want the creation of List to be dependent on the type of variable. This code doesn\'t work:

using System;         


        

Answer 1

string something = "Apple";
Type type = something.GetType();
Type listType = typeof(List<>).MakeGenericType(new [] { type } );
IList list = (IList)Activator.CreateInstance(listType);

This is how you create a list of statically unknown type. But notice that you are unable to mention the runtime type of the list statically. You have to use a non-generic type or even object.

Without knowing more about what you want to accomplish this is the best you can do.
