備註

方法 Subtraction 會針對值定義減法運算子的運算 Decimal 。 它會啟用下列程式碼：

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

let number1 = 120.07m
let number2 = 163.19m
let number3 = number1 - number2
printfn $"{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

如果您使用的語言不支援自訂運算子，請改為呼叫 Subtract 方法。

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