To add to Jonas' answer, you don't have to create a new var p. Use this approach instead:

using System;
using System.Dynamic;

class Program
{
    static void Main(string[] args)
    {
        dynamic expando = new ExpandoObject();
        ((IDictionary)expando)["A"] = "New val 1";
        ((IDictionary)expando)["B"] = "New val 2";

        Console.WriteLine(expando.A);
        Console.WriteLine(expando.B);
    }
}
