定义

将两个指定的 Decimal 值相减。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

参数

d1
Decimal

被减数。The minuend.

d2
Decimal

减数。The subtrahend.

返回

d2d1 所得的结果。The result of subtracting d2 from d1.

异常

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

注解

Subtraction 方法为 Decimal 值定义减法运算符的运算。The Subtraction method defines the operation of the subtraction 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 = 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

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

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