Instantiating Types

There are two ways to dynamically instantiate an object from its type:

• Call Activator.CreateInstance method
• Call Invoke on a ConstructorInfo object obtained from a Type

Activator.CreateInstance accepts a Type and optional arguments that get passed to the constructor:

using System;
using System.Reflection;
using System.Collections.Generic;

class MainClass
{
    static void Main()
    {
        int i = (int)Activator.CreateInstance(typeof(int));

        DateTime dt = (DateTime)Activator.CreateInstance(typeof(DateTime),2000, 1, 1);

    }

}
