減去兩個指定的 Decimal 值。

public:
 static System::Decimal operator -(System::Decimal d1, System::Decimal d2);
public:
 static System::Decimal operator -(System::Decimal d1, System::Decimal d2) = System::Numerics::ISubtractionOperators<System::Decimal, System::Decimal, System::Decimal>::op_Subtraction;
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

最重要。

d2
Decimal

副底線。

傳回

Decimal

從 中減去 d2d1的結果。

實作

Subtraction(TSelf, TOther)

例外狀況

OverflowException

回傳值小於 Decimal.MinValue ，或大於 Decimal.MaxValue。

備註

此 Subtraction 方法定義了值的減法運算 Decimal 子。 它啟用了以下程式碼：

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

如果你使用的語言不支援自訂運算子，那就直接呼叫該 Subtract 方法。
