Decimal.LessThanOrEqual(Decimal, Decimal) 操作员

定义

返回一个值,该值指示指定的 Decimal 是小于还是等于另一个指定的 DecimalReturns a value indicating whether a specified Decimal is less than or equal to another specified Decimal.

public:
 static bool operator <=(System::Decimal d1, System::Decimal d2);
public static bool operator <= (decimal d1, decimal d2);
static member ( <= ) : 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 d1 小于等于 d2,则为 true;否则为 falsetrue if d1 is less than or equal to d2; otherwise, false.

注解

LessThanOrEqual 方法定义 Decimal 值的小于或等于运算符的运算。The LessThanOrEqual method defines the operation of the less than or equal 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 = 16354.0699m;
      Decimal number2 = 16354.0695m;
      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:
//       16354.0699 <= 16354.0695: False
//       16354.07 <= 16354.07: True
Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16354.0699d
      Dim number2 As Decimal = 16354.0695d
      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:
'       16354.0699 <= 16354.0695: False
'       16354.07 <= 16354.07: True

不支持自定义运算符的语言可以改为调用 Compare 方法。Languages that do not support custom operators can call the Compare method instead. 它们还可以直接调用 LessThanOrEqual 方法,如下例所示。They may also be able to call the LessThanOrEqual method directly, as the following example shows.

Module Example
   Public Sub Main()
      Dim number1 As Decimal = 16354.0699d
      Dim number2 As Decimal = 16354.0695d
      Console.WriteLine("{0} <= {1}: {2}", number1, number2, 
                        Decimal.op_LessThanOrEqual(number1, number2))

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

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)
