推荐答案

使用

Use TotalHours instead of Hours. Note that the result is a double - you can just cast it to int to get the whole number of hours. (Check what behaviour you want if the result is negative though...)

从文档中获取小时:

属性值:当前TimeSpan结构的小时部分.返回值的范围是-23到23

Property Value: The hour component of the current TimeSpan structure. The return value ranges from -23 through 23

您不需要小时 -您需要整个时间段，以小时为单位.

You don't want the hour component - you want the whole time span, expressed in hours.
