Create a list of an Anonymous Type

AnonList.cs

class AnonList
{

	/// <summary>
	/// Creates a list of type T using a prototype object. Prototype can be any object, including an anonymous type. 
	/// </summary>
	/// <typeparam name="T"></typeparam>
	/// <param name="prototype">The prototype object, of which a List of the same type is returned</param>
	/// <returns>A new empty List of the same type as prototype</returns>
	public static List<T> CreateAnonList<T>(T prototype)
	{
		return new List<T>();
	}

}

FYI: I wouldn't recommend tricks like these for real code. If you need to result to this trick, you may want to rethink your data types :)
