推荐答案

你好，



尝试使用TimeSpan或搜索TimeSpan示例。

hello,

try to use use TimeSpan or search TimeSpan example.

thanks

尝试

Try

DateTime dt1 = DateTime.ParseExact(time1, "HH:mm:ss", new DateTimeFormatInfo());
DateTime dt2 = DateTime.ParseExact(time2, "HH:mm:ss", new DateTimeFormatInfo());
TimeSpan ts = dt1.Subtract(dt2);

一个改进：在Abhinav的解决方案中，写下最后一行更好这个：

One improvement: in the solution by Abhinav, it's much better to write the last line like this:

TimeSpan ts = dt1 - dt2;
//yes, subtraction operator "-" is defined, of course
