转载 传递引用类型参数(ref)
引用类型的变量不直接包含其数据；它包含的是对其数据的引用。 当通过值传递引用类型的参数时，有可能更改引用所指向的数据，如某类成员的值。 但是无法更改引用本身的值；也就是说，不能使用相同的引用为新类分配内存并使之在块外保持。 若要这样做，应使用 ref 或 out 关键字传递参数。

CLR管理内存的区域，主要有三块，分别为：1.线程的堆栈：（在程序应该编译过程为值类型实例分配好内存）用于分配值类型实例。堆栈主要由操作系统管理，而不受垃圾收集器的控制，当值类型实例所在方法结束时，其存储单位自动释放。栈的执行效率高，但存储容量有限。对于值类型来说，一般创建在线程的堆栈上。但并非所有的值类型都创建在线程的堆栈上，例如作为类的字段时，值类型作为实例成员的一部分

原创 值类型，引用类型，装箱，拆箱
装箱是将值类型转换为 object 类型或由此值类型实现的任何接口类型的过程。 当 CLR 对值类型进行装箱时，会将该值包装到 System.Object 内部，再将后者存储在托管堆上。 取消装箱将从对象中提取值类型。 装箱是隐式的；取消装箱是显式的。 装箱和取消装箱的概念是类型系统 C# 统一视图的基础，其中任一类型的值都被视为一个对象。
