Specifying generic collection type param at runtime [duplicate]

Question

I have:

class Car {..} class Other{   List<T> GetAll(){..} } 

I want to do:

Type t = typeof(Car); List<t> Cars = GetAll<t>(); 

How can I do this?

I want to return a generic collection from the database of a type that I discover at runtime using reflection.

Answer 1

Type generic = typeof(List<>);     Type specific = generic.MakeGenericType(typeof(int));     ConstructorInfo ci = specific.GetConstructor(Type.EmptyTypes);     object o = ci.Invoke(new object[] { }); 

Answer 2

You could use reflection for this:

Type t = typeof(Car); System.Type genericType= generic.MakeGenericType(new System.Type[] { t}); Activator.CreateInstance(genericType, args);
