Using C# reflection to call a constructor

by

I don’t think GetMethod will do it, no – but GetConstructor will.

using System;
using System.Reflection;

class Addition
{
    public Addition(int a)
    {
        Console.WriteLine("Constructor called, a={0}", a);
    }
}

class Test
{
    static void Main()
    {
        Type type = typeof(Addition);
        ConstructorInfo ctor = type.GetConstructor(new[] { typeof(int) });
        object instance = ctor.Invoke(new object[] { 10 });
    }
}

EDIT: Yes, Activator.CreateInstance will work too. Use GetConstructor if you want to have more control over things, find out the parameter names etc. Activator.CreateInstance is great if you just want to call the constructor though.
