How to mutate a boxed struct using IL

Question

Imagine we have a mutable struct (yes, don\'t start):

public struct MutableStruct
{
    public int Foo { get; set; }
    public override string

You can do this even easier. Try this under .NET 4.5 where we have dynamic.

struct Test
{
    public Int32 Number { get; set; }


    public override string ToString()
    {
        return this.Number.ToString();
    }
}


class Program
{
    static void Main( string[] args )
    {
        Object test = new Test();

        dynamic proxy = test;

        proxy.Number = 1;

        Console.WriteLine( test );
        Console.ReadLine();
    }
}

I know it's not reflection but still fun though.
