Specifying generic collection type param at runtime [duplicate]
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.
Solution 1:
Type generic = typeof(List<>);
Type specific = generic.MakeGenericType(typeof(int));
ConstructorInfo ci = specific.GetConstructor(Type.EmptyTypes);
object o = ci.Invoke(new object[] { });
Solution 2:
You could use reflection for this:
Type t = typeof(Car);
System.Type genericType= generic.MakeGenericType(new System.Type[] { t});
Activator.CreateInstance(genericType, args);
