Decimal.Multiply(Decimal, Decimal) 运算符

定义

两个指定的 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

参数

d1
Decimal

要相乘的第一个值。The first value to multiply.

d2
Decimal

要相乘的第二个值。The second value to multiply.

返回

d1d2 相乘的结果。The result of multiplying d1 by d2.

异常

返回值小于 MinValue 或大于 MaxValueThe return value is less than MinValue or greater than MaxValue.

注解

Multiply 方法定义了 Decimal 值的乘法运算符的运算。The Multiply method defines the operation of the multiplication operator for Decimal values. 它可以实现如下所示的代码: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

如果正在使用的语言不支持自定义运算符,请改为调用 Multiply 方法。If the language you're using doesn't support custom operators, call the Multiply method instead.

此运算符的等效方法是 Decimal.Multiply(Decimal, Decimal)The equivalent method for this operator is Decimal.Multiply(Decimal, Decimal)
