TimeSpan.Subtraction(TimeSpan, TimeSpan) 運算子

定義

命名空間:

System

組件:

System.Runtime.dll

來源:

TimeSpan.cs

將指定的 TimeSpan 從另一個指定的 TimeSpan 減掉。

public:
 static TimeSpan operator -(TimeSpan t1, TimeSpan t2);

public static TimeSpan operator - (TimeSpan t1, TimeSpan t2);

static member ( - ) : TimeSpan * TimeSpan -> TimeSpan

Public Shared Operator - (t1 As TimeSpan, t2 As TimeSpan) As TimeSpan

參數

t1

TimeSpan

被減數。

t2

TimeSpan

減數。

傳回

TimeSpan

物件，其值為 t1 值減去 t2 值的結果。

例外狀況

OverflowException

傳回值小於 TimeSpan.MinValue 或大於 TimeSpan.MaxValue。

範例

下列範例會 TimeSpan 使用減法運算子來計算每週工作日的總長度。 它也會使用 TimeSpan 加法運算子來計算每日中斷的總時間，再將其用於減法運算，以計算實際每日工作時間總計。

var startWork = new TimeSpan(08,00,00);
var endWork = new TimeSpan(18,30,00);
var lunchBreak = new TimeSpan(1, 0, 0);
var breaks = new TimeSpan(0, 30, 0);

Console.WriteLine("Length of work day: {0}", 
                  endWork - startWork);
Console.WriteLine("Actual time worked: {0}",
                  endWork - startWork - (lunchBreak + breaks));                  

// The example displays the following output:
//     Length of work day: 10:30:00
//     Actual time worked: 09:00:00

let startWork = TimeSpan(08,00,00)
let endWork = TimeSpan(18,30,00)
let lunchBreak = TimeSpan(1, 0, 0)
let breaks = TimeSpan(0, 30, 0)

printfn $"Length of work day: {endWork - startWork}"
printfn $"Actual time worked: {endWork - startWork - (lunchBreak + breaks)}"

// The example displays the following output:
//     Length of work day: 10:30:00
//     Actual time worked: 09:00:00

Module Example
   Public Sub Main()
      Dim startWork As New TimeSpan(08,00,00)
      Dim endWork As New TimeSpan(18,30,00)
      Dim lunchBreak As New TimeSpan(1, 0, 0)
      Dim breaks As New TimeSpan(0, 30, 0)
      
      Console.WriteLine("Length of work day: {0}", 
                        endWork - startWork)
      Console.WriteLine("Actual time worked: {0}",
                        endwork - startwork - (lun\chBreak + breaks))                  
   End Sub
End Module
' The example displays the following output:
'     Length of work day: 10:30:00
'     Actual time worked: 09:00:00

備註

這個運算子的對等方法為 TimeSpan.Subtract(TimeSpan)
