关于TimeSpan

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 = ;
