This differs from the assignment of reference type variables, which copies a reference to the object but not the object itself.
这与引用类型变量的赋值不同，引用类型变量的赋值只复制对对象的引用，而不复制对象本身。
Finally, the string type is a reference type, so every string instance refers to an additional block of memory to hold the actual string data.
最后，字符串类型是引用类型，因此每个字符串实例都引用一个附加的内存块，以存放实际的字符串数据。
It might be worth considering an enumeration here since it would remove the need for a reference type and store the value directly in the class.
