TimeSpan.Subtraction(TimeSpan, TimeSpan) TimeSpan.Subtraction(TimeSpan, TimeSpan) TimeSpan.Subtraction(TimeSpan, TimeSpan) TimeSpan.Subtraction(TimeSpan, TimeSpan) Operator

定義

指定したもう 1 つの TimeSpan から、指定した TimeSpan を減算します。Subtracts a specified TimeSpan from another specified TimeSpan.

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

パラメーター

t1
TimeSpan TimeSpan TimeSpan TimeSpan

被減数。The minuend.

t2
TimeSpan TimeSpan TimeSpan TimeSpan

減数。The subtrahend.

戻り値

t2 の値から t1 の値を減算した結果を値とするオブジェクト。An object whose value is the result of the value of t1 minus the value of t2.

例外

戻り値が MinValue 未満であるか、MaxValue を超えています。The return value is less than MinValue or greater than MaxValue.

次の例では、TimeSpan減算演算子を週単位の作業日の合計の長さを計算します。The following example uses the TimeSpan subtraction operator to calculate the total length of the weekly work day. また、使用、TimeSpan減算演算の毎日の作業時間の実際の合計を計算するために使用する前に日単位の区切りの時間の合計を計算する加算演算子。It also uses the TimeSpan addition operator to compute the total time of the daily breaks before using it in a subtraction operation to compute the total actual daily working time.

using System;

public class Example
{
   public static void Main()
   {
      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
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
