推荐答案

尝试：

Try:

string break1 = "10:00:00 AM";
DateTime sys_time = DateTime.Now;

DateTime sys_timeToday = DateTime.ParseExact(break1, "hh:mm:ss tt",CultureInfo.InvariantCulture);
TimeSpan diff = sys_timeToday - sys_time;
Console.WriteLine("Diff: {0} hours, {1} mins, and {2} seconds", diff.Hours, diff.Minutes, diff.Seconds);

使用 Convert.ToDateTime [ ^ ]将 break1 转换为 DateTime 对象，然后初始化 TimeSpan [ ^ ]对象与两个<$ c之间的差异$ c> DateTime objects。

Use Convert.ToDateTime[^] to convert break1 to a DateTime object and then initialize a TimeSpan[^] object with the difference between the two DateTime objects.

试试这个.. :)

Try this.. :)

string startTime = "10:00:00 AM";
string endTime = Convert.ToString(DateTime.Now);

TimeSpan duration = DateTime.Parse(endTime).Subtract(DateTime.Parse(startTime));
