一秒是1000万个tick
TimeSpan ts = new TimeSpan( * );
Console.WriteLine(ts);
Console.Read();
//print 00:00:01
并且在TimeSpan的类里都有常量定义
public const long TicksPerDay = ; public const long TicksPerHour = ; public const long TicksPerMillisecond = ; public const long TicksPerMinute = ; public const long TicksPerSecond = ;
