Decimal.Equality(Decimal, Decimal) Decimal.Equality(Decimal, Decimal) Decimal.Equality(Decimal, Decimal) Decimal.Equality(Decimal, Decimal) Operator

定義

傳回值,指出兩個 Decimal 值是否相等。Returns a value that indicates whether two Decimal values are equal.

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

參數

d1
Decimal Decimal Decimal Decimal

要比較的第一個值。The first value to compare.

d2
Decimal Decimal Decimal Decimal

要比較的第二個值。The second value to compare.

傳回

如果 d1d2 相等,則為 true;否則為 falsetrue if d1 and d2 are equal; otherwise, false.

備註

方法會定義Decimal值的等號比較運算子的運算。 EqualityThe Equality method defines the operation of the equality operator for Decimal values. 它會啟用如下所示的程式碼: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: False
//       16354.07 = 16354.07: True
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: False
'       16354.07 = 16354.07: True

如果您所使用的語言不支援自訂運算子,請Equals改為呼叫方法。If the language you're using doesn't support custom operators, call the Equals method instead.

這個運算子的對等方法是Decimal.Equals(Object)The equivalent method for this operator is Decimal.Equals(Object)
