问题描述
当我比较日期和时间时，如果超过24小时意味着它显示为例如25小时1.01：00：001天加1小时。我想要这样的结果25:00:00小时。
请帮帮我...

推荐答案
DateTime now = DateTime.Now;
DateTime then = now.AddDays(-1).AddHours(-1);
TimeSpan diff = now - then;
Console.WriteLine("{0}:{1}:{2}", (int)diff.TotalHours, diff.Minutes, diff.Seconds);
DateTime random = new DateTime(2013, 2, 24, 7, 56, 23);
diff = now - random;
Console.WriteLine("{0}:{1}:{2}", (int)diff.TotalHours, diff.Minutes, diff.Seconds);
您需要将TotalHours转换为int，因为它将时间差作为double返回，其中分钟和秒作为小数部分。
You need to cast the TotalHours to an int, as it returns the difference in time as a double, with the minutes and seconds as the fractional part.
