C#，没有关联字段的属性，存储数据的问题

Affirmative

最近在看图解C#这本书，里面有一个章节：“6.18 访问器的访问修饰符”源代码：


因为我之前看的时候，说是属性没有内存空间，一般是关联字段进行存取。
但是看这个案例里面，Name这个属性直接就用了。我比较疑惑，有人可以解释下吗？

往前翻书自己找到原理了，“自动实现属性”会隐式创建字段关联属性。

Automatically Implemented Properties—Auto-properties
Because properties are so often associated with backing fields, C# provides automatically implemented
properties, also called auto-implemented properties or, more commonly, just auto-properties, which allow
you to declare the property without declaring a backing field. The compiler creates a hidden backing field for
you and automatically hooks up the get and set accessors to it.
