DateTime.Ticks 屬性

定義

取得代表此實例日期與時間的勾數。

public:
 property long Ticks { long get(); };
public long Ticks { get; }
member this.Ticks : int64
Public ReadOnly Property Ticks As Long

屬性值

代表此事件日期與時間的勾數。 值介於 DateTime.MinValue.TicksDateTime.MaxValue.Ticks之間。

範例

以下範例利用該 Ticks 性質顯示自二十一世紀初以來經過的tick數,並實例化物件 TimeSpan 。 接著,該 TimeSpan 物件用來顯示經過的時間,並使用其他多個時間區間。

DateTime centuryBegin = new DateTime(2001, 1, 1);
DateTime currentDate = DateTime.Now;

long elapsedTicks = currentDate.Ticks - centuryBegin.Ticks;
TimeSpan elapsedSpan = new TimeSpan(elapsedTicks);

Console.WriteLine("Elapsed from the beginning of the century to {0:f}:",
                   currentDate);
Console.WriteLine("   {0:N0} nanoseconds", elapsedTicks * 100);
Console.WriteLine("   {0:N0} ticks", elapsedTicks);
Console.WriteLine("   {0:N2} seconds", elapsedSpan.TotalSeconds);
Console.WriteLine("   {0:N2} minutes", elapsedSpan.TotalMinutes);
Console.WriteLine("   {0:N0} days, {1} hours, {2} minutes, {3} seconds",
                  elapsedSpan.Days, elapsedSpan.Hours,
                  elapsedSpan.Minutes, elapsedSpan.Seconds);

// This example displays an output similar to the following:
//
// Elapsed from the beginning of the century to Thursday, 14 November 2019 18:21:
//    595,448,498,171,000,000 nanoseconds
//    5,954,484,981,710,000 ticks
//    595,448,498.17 seconds
//    9,924,141.64 minutes
//    6,891 days, 18 hours, 21 minutes, 38 seconds

備註

一個刻度代表一百奈秒或千萬分之一秒。 每毫秒有10,000個滴答(參見 TicksPerMillisecond),每秒有1,000萬個滴答。

此性質的值代表自公曆0001年1月1日午夜12:00:00以來,經過的100奈秒間隔數,代表 MinValue。 它不包含因閏秒而產生的刻度數。 若 DateTime 物件的屬性設定 KindLocal,其刻數代表自當地時間 0001 年 1 月 1 日午夜 12:00:00 起,依據當前時區設定所規定的時間經過時間。 若物件 DateTime 屬性設定 KindUtc,其刻數代表自協調世界時 0001 年 1 月 1 日午夜 12:00:00 以來的經過時間。 若 DateTime 物件屬性設定 KindUnspecified,其刻度表示自 0001 年 1 月 1 日午夜 12:00:00 起在未知時區的經過時間。

一般來說,刻度代表根據屬性 Kind 指定的時區所定的時間。
