有時候你可能需要定義類來封裝一些資料，但並不需要任何方法、事件和其他自定義的功能。或者說你需要定義一個只是用於當前程式的臨時型別，在這種情況下，匿名型別將會派上用場。請看下面的程式碼：

using System;

namespace Com.LoonStudio {

	class Program {
		static void Main() {
			// 定義匿名型別
			var car1 = new { Brand = "Benz", MaxSpeed = 200 };
			var car2 = new { Brand = "Benz", MaxSpeed = 200 };
			Console.WriteLine(car1.Equals(car2));	// true（基於值的語義進行比較）
			Console.WriteLine(car1 == car2);		// false
			Console.WriteLine(car1.GetType() == car2.GetType());	// true
			Console.WriteLine(car1.GetType().Name);	// <>f__AnonymouseType0`2
			Console.WriteLine(car1.ToString());		// { Brand = Benz, MaxSpeed = 200 }

			// 包含匿名型別的匿名型別
			var person = new {
						Name = "Hao", RegDate = DateTime.Now, 
						Car = new {Brand = "Benz", MaxSpeed = 200}
			};
			Console.WriteLine(person.Car.Brand);	// Benz
			Console.WriteLine(person);	// { Name = Hao, RegDate = 2013/12/6 23:12:17, Car = { Brand = Benz, MaxSpeed = 200 } }
		}
	}
