Example of working with anonymous types in Unity3d

gistfile1.cs

using System;
using System.Collections;
using UnityEngine;

public class Testing : MonoBehaviour
{
	void Start()
	{
		// In C#, this is an 'Anonymous Type'
		// A new System.Type is generated for it at compile type
		var anonymous = new {
			Foo = "The meaning of life.",
			Bar = 42,
		};

		Debug.Log("anonymous.foo: " + anonymous.Foo);		// prints "The meaning of life."
		Debug.Log("anonymous.bar: " + anonymous.Bar);		// prints 42
		//Debug.Log("anonymous type: " + typeof(anonymous));	// compile error

		// So 'Anonymous Type' is kind of like a dynamic object in AS,
		// except there are some major disavantages...

		// 1) You can't add members after creation
		//anonymous.Baz = "Attempt to add.";			// compile error

		// 2) The values are read only
		//anonymous.Foo = "Not the meaning of life.";		// compile error

		// 3) They can't be passed around... easily
		passTest(anonymous);
	}

	void passTest(object obj)
	{
		// There isn't a good way to access its members now.
		// Because I don't know its type.

		// However, there is a hack...
		var anonymous = AnonymousCast(obj, new { Foo = "", Bar = 0 });
		Debug.Log("anonymous.foo: " + anonymous.Foo);		// prints "The meaning of life."
		Debug.Log("anonymous.bar: " + anonymous.Bar);		// prints 42

		// This hack works because the C# specification says:
		// If two anonymous objects are created with the same properties,
		// and in the same order, the same 'anonymous type' will be
		// generated by the compiler.

		// Runtime error: InvalidCastException
		//var bad1 = AnonymousCast(obj, new { Bar = "", Foo = 0 });
		//var bad2 = AnonymousCast(obj, new { Bar = 0, Foo = "" });
	}
	
	T AnonymousCast<T>(object obj, T aType)
	{
		return (T) obj;
	}
