Specifying generic collection type param at runtime [duplicate]

Answer 1

You could use reflection for this:

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

Answer 2

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