一、TimeSpan基础知识
使用TimeSpan对象可以方便地获取两个时间段的间隔。两个时间信息相减后会得到一个TimeSpan对象，该TimeSpan对象代表时间间隔，可以通过TimeSpan对象的Days、Hours、Minutes、Seconds、Milliseconds属性分别得到间隔的天、时、分、秒、毫秒数。
TimeSpan对象代表两个时间段的间隔或跨度，使用TimeSpan对象可以方便地获取两个时间段的间隔。两个时间信息相减后会得到一个TimeSpan对象，该TimeSpan对象代表时间间隔，可以通过TimeSpan对象的Days、Hours、Minutes、Seconds、Milliseconds属性分别得到间隔的天、时、分、秒、毫秒数。
可以调用TimeSpan的Add方法，得到两个TimeSpan持续时间的和。
二、实例
