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

I want type safety but I need dynamic type safety.

If you mean you want runtime type-safety, you can create List using reflection (see usr's answer) or dynamic and then treat it as the non-generic IList.

Using dynamic, it would look something like this:

static List CreateListByExample(T obj)
{
    return new List();
}

…

object something = "Apple";

IList list = CreateListByExample((dynamic)something);

list.Add(something); // OK

list.Add(42);        // throws ArgumentException
