Decimal.Multiply(Decimal, Decimal) Decimal.Multiply(Decimal, Decimal) Decimal.Multiply(Decimal, Decimal) Decimal.Multiply(Decimal, Decimal) Operator

定義

將兩個指定的 Decimal 值相乘。Multiplies 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

要相乘的第一個值。The first value to multiply.

d2
Decimal Decimal Decimal Decimal

要相乘的第二個值。The second value to multiply.

傳回

d1 乘以 d2 的結果。The result of multiplying d1 by d2.

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值定義乘法運算子的運算。 MultiplyThe Multiply method defines the operation of the multiplication 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 = 16.8m;
      Decimal number2 = 4.1m;
      Decimal number3 = number1 * number2;
      Console.WriteLine("{0:N2} x {1:N2} = {2:N2}", 
                        number1, number2, number3);
   }
}
// The example displays the following output:
//        16.80 x 4.10 = 68.88
Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16.8d 
      Dim number2 As Decimal = 4.1d 
      Dim number3 As Decimal = number1 * number2
      Console.WriteLine("{0:N2} x {1:N2} = {2:N2}", 
                        number1, number2, number3)
   End Sub
End Module
' The example displays the following output:
'       16.80 x 4.10 = 68.88

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

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