Decimal.Inequality(Decimal, Decimal) 运算符

定义

返回一个值,该值指示两个 Decimal 对象是否具有不同的值。Returns a value that indicates whether two Decimal objects have different values.

public:
 static bool operator !=(System::Decimal d1, System::Decimal d2);
public static bool operator != (decimal d1, decimal d2);
static member op_Inequality : decimal * decimal -> bool
Public Shared Operator != (d1 As Decimal, d2 As Decimal) As Boolean

参数

d1
Decimal

要比较的第一个值。The first value to compare.

d2
Decimal

要比较的第二个值。The second value to compare.

返回

如果 trued1 不相等,则为 d2;否则为 falsetrue if d1 and d2 are not equal; otherwise, false.

注解

Inequality 方法为 Decimal 值定义不相等运算符的运算。The Inequality method defines the operation of the inequality 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 = 16354.0695m;
      Decimal number2 = 16354.0699m;
      Console.WriteLine("{0} <> {1}: {2}", number1, 
                        number2, number1 != number2);

      number1 = Decimal.Round(number1, 2);
      number2 = Decimal.Round(number2, 2);
      Console.WriteLine("{0} <> {1}: {2}", number1, 
                        number2, number1 != number2);
   }
}
// The example displays the following output:
//       16354.0695 = 16354.0699: True
//       16354.07 = 16354.07: False
Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16354.0695d
      Dim number2 As Decimal = 16354.0699d
      Console.WriteLine("{0} <> {1}: {2}", number1, 
                        number2, number1 <> number2)

      number1 = Decimal.Round(number1, 2)
      number2 = Decimal.Round(number2, 2)
      Console.WriteLine("{0} <> {1}: {2}", number1, 
                        number2, number1 <> number2)
   End Sub
End Module
' The example displays the following output:
'       16354.0695 = 16354.0699: True
'       16354.07 = 16354.07: False

如果正在使用的语言不支持自定义运算符,可以使用以下方法之一来测试是否不相等:If the language you're using doesn't support custom operators, you can test for inequality by using one of the following techniques:

  • 调用 Compare 方法,该方法指示两个 Decimal 值之间的关系。Calling the Compare method, which indicates the relationship between two Decimal values.

  • 调用 Equals 方法并反转其值。Calling the Equals method and reversing its value.

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