Question

I want to do something like the code below.

    public IList SomeMethod(Type t)
    { 
        List<t> list = new List<t>;
        return list;
    }

This, of course, does not work. Is there some other way I can dynamically set the type parameter of a generic class using a reference to a Type instance?

Answer 1

Try this:

public IList SomeMethod(Type t)
{ 
    Type listType = typeof(List<>);
    listType = listType.MakeGenericType(new Type[] { t});
    return (IList)Activator.CreateInstance(listType);
}
