Decimal.LessThan(Decimal, Decimal) 运算符

定义

返回一个值,该值指示指定的 Decimal 是否小于另一个指定的 Decimal

public:
 static bool operator <(System::Decimal d1, System::Decimal d2);
public:
 static bool operator <(System::Decimal d1, System::Decimal d2) = System::Numerics::IComparisonOperators<System::Decimal, System::Decimal, bool>::op_LessThan;
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。

d2
Decimal

要比较的第二个值。

返回

如果 d1 小于 d2,则为 true;否则为 false

实现

注解

方法 LessThan 为值定义小于 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 = 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: False
open System

let number1 = 16354.0699m
let number2 = 16354.0695m
printfn $"{number1} < {number2}: {number1 < number2}"

let rounded1 = Decimal.Round(number1, 2)
let rounded2 = Decimal.Round(number2, 2)
printfn $"{rounded1} < {rounded2}: {rounded1 < rounded2}"

// The example displays the following output:
//       16354.0699 < 16354.0695: False
//       16354.07 < 16354.07: False
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: False

不支持自定义运算符的语言可以改为调用 Compare 方法。 他们还可以直接调用 LessThan 方法,如以下示例所示。

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_LessThan(number1, number2))

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

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