定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

Decimal.cs

将两个指定的 Decimal 值相减。

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

参数

d1

Decimal

被减数。

d2

Decimal

减数。

返回

Decimal

d2 减 d1 所得的结果。

实现

Subtraction(TSelf, TOther)

例外

OverflowException

返回值小于 Decimal.MinValue 或大于 Decimal.MaxValue。

注解

方法 Subtraction 定义值的减法运算符的操作 Decimal 。 它启用如下代码：

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

如果使用的语言不支持自定义运算符，请改为调用 Subtract 方法。

此运算符的等效方法是 Decimal.Subtract(Decimal, Decimal)
