+ 说明：System.DateTime类型不是class，而是一个struct，换言之它是值类型，而不是引用类型。

+ 该属性的类型为System.DateTimeKind枚举。DateTimeKind定义如下，它具有三个枚举值：Unspecified、Utc和Local。
+ 后两个分别表示UTC（格林威治时间）和本地时间。Unspecified顾名思义，就是尚未指定具体类型，这是默认值。

+ 虽然，Kind属性是只读的，但是我们还用另外一中设定Kind的方式，那就是调用DateTime的静态方法的SpecifyKind。该方法不会真正去修改一个现有DateTime对象的Kind属性，而是会重新创建一个新的DateTime对象。方法返回的对象具有和指定时间相同的基本属性（年、月、日、时、分、秒和毫秒），该DateTime对象具有你指定的DateTimeKind值。
