TimeSpan.Add(TimeSpan) 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

TimeSpan.cs

返回一个新的 TimeSpan 对象，其值为指定的 TimeSpan 对象与此实例的值之和。

public:
 TimeSpan Add(TimeSpan ts);

public TimeSpan Add (TimeSpan ts);

member this.Add : TimeSpan -> TimeSpan

Public Function Add (ts As TimeSpan) As TimeSpan

参数

ts

TimeSpan

待添加的时间间隔。

返回

TimeSpan

一个新对象，表示此实例的值加 ts 的值。

例外

OverflowException

生成的 TimeSpan 小于 TimeSpan.MinValue 或大于 TimeSpan.MaxValue。

示例

以下示例调用 Add 方法，将时间间隔数组中的每个元素添加到基 TimeSpan 值。

TimeSpan baseTimeSpan = new TimeSpan(1, 12, 15, 16);

// Create an array of timespan intervals.
TimeSpan[] intervals = { 
   TimeSpan.FromDays(1.5), 
   TimeSpan.FromHours(1.5), 
   TimeSpan.FromMinutes(45), 
   TimeSpan.FromMilliseconds(505),
   new TimeSpan(1, 17, 32, 20), 
   new TimeSpan(-8, 30, 0) 
};

// Calculate a new time interval by adding each element to the base interval.
foreach (var interval in intervals)
   Console.WriteLine(@"{0,-10:g} {3} {1,15:%d\:hh\:mm\:ss\.ffff} = {2:%d\:hh\:mm\:ss\.ffff}", 
                     baseTimeSpan, interval, baseTimeSpan.Add(interval), 
                     interval < TimeSpan.Zero ? "-" : "+");

// The example displays the following output:
//       1:12:15:16 + 1:12:00:00.0000 = 3:00:15:16.0000
//       1:12:15:16 + 0:01:30:00.0000 = 1:13:45:16.0000
//       1:12:15:16 + 0:00:45:00.0000 = 1:13:00:16.0000
//       1:12:15:16 + 0:00:00:00.5050 = 1:12:15:16.5050
//       1:12:15:16 + 1:17:32:20.0000 = 3:05:47:36.0000
//       1:12:15:16 - 0:07:30:00.0000 = 1:04:45:16.0000

open System

let baseTimeSpan = TimeSpan(1, 12, 15, 16)

// Create a list of timespan intervals.
let intervals = 
    [ TimeSpan.FromDays 1.5 
      TimeSpan.FromHours 1.5 
      TimeSpan.FromMinutes 45
      TimeSpan.FromMilliseconds 505
      TimeSpan(1, 17, 32, 20) 
      TimeSpan(-8, 30, 0) ]

// Calculate a new time interval by adding each element to the base interval.
for interval in intervals do
   printfn $"""{baseTimeSpan,-10:g} {if interval < TimeSpan.Zero then "-" else "+"} {interval.ToString "%d\:hh\:mm\:ss\.ffff",15} = {baseTimeSpan.Add(interval).ToString "%d\:hh\:mm\:ss\.ffff"}""" 

// The example displays the following output:
//       1:12:15:16 + 1:12:00:00.0000 = 3:00:15:16.0000
//       1:12:15:16 + 0:01:30:00.0000 = 1:13:45:16.0000
//       1:12:15:16 + 0:00:45:00.0000 = 1:13:00:16.0000
//       1:12:15:16 + 0:00:00:00.5050 = 1:12:15:16.5050
//       1:12:15:16 + 1:17:32:20.0000 = 3:05:47:36.0000
//       1:12:15:16 - 0:07:30:00.0000 = 1:04:45:16.0000

注解

返回值必须介于 和 TimeSpan.MaxValue之间TimeSpan.MinValue;否则会引发异常。

返回值为新的 TimeSpan;原始 TimeSpan 值不会修改。
