Decimal.Subtraction(Decimal, Decimal) Decimal.Subtraction(Decimal, Decimal) Decimal.Subtraction(Decimal, Decimal) Decimal.Subtraction(Decimal, Decimal) Operator

定義

將兩個指定的 Decimal 值相減。Subtracts two specified Decimal values.

public:
 static System::Decimal operator -(System::Decimal d1, System::Decimal d2);
public static decimal operator - (decimal d1, decimal d2);
static member ( - ) : decimal * decimal -> decimal
Public Shared Operator - (d1 As Decimal, d2 As Decimal) As Decimal

參數

d1
Decimal Decimal Decimal Decimal

被減數。The minuend.

d2
Decimal Decimal Decimal Decimal

減數。The subtrahend.

傳回

d2 減去 d1 的結果。The result of subtracting d2 from d1.

例外狀況

傳回值小於 MinValue 或大於 MaxValueThe return value is less than MinValue or greater than MaxValue.

備註

方法會針對Decimal值定義減法運算子的運算。 SubtractionThe Subtraction method defines the operation of the subtraction operator for Decimal values. 它會啟用如下所示的程式碼:It enables code such as the following:

using System;

public class Example
{
   public static void Main()
   {
      Decimal number1 = 120.07m;
      Decimal number2 = 163.19m;
      Decimal number3 = number1 - number2;
      Console.WriteLine("{0} - {1} = {2}", 
                        number1, number2, number3);
   }
}
// The example displays the following output:
//        120.07 - 163.19 = -43.12
Module Example
   Public Sub Main()
      Dim number1 As Decimal = 120.07d 
      Dim number2 As Decimal = 163.19d 
      Dim number3 As Decimal = number1 - number2
      Console.WriteLine("{0} - {1} = {2}", 
                        number1, number2, number3)
   End Sub
End Module
' The example displays the following output:
'       120.07 - 163.19 = -43.12

如果您所使用的語言不支援自訂運算子,請Subtract改為呼叫方法。If the language you're using doesn't support custom operators, call the Subtract method instead.

這個運算子的對等方法是Decimal.Subtract(Decimal, Decimal)The equivalent method for this operator is Decimal.Subtract(Decimal, Decimal)
