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

## 定義

2 つの Decimal 値が等しいかどうかを示す値を返します。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

#### パラメーター

d1
Decimal Decimal Decimal Decimal

d2
Decimal Decimal Decimal Decimal

#### 戻り値

trued1 が等しい場合は d2。それ以外の場合は falsetrue if d1 and d2 are equal; otherwise, false.

## 注釈

メソッドEqualityは、値のDecimal等値演算子の演算を定義します。The Equality method defines the operation of the equality operator for Decimal values. 次のようなコードが有効になります。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

この演算子の同等の方法は次のようになります。Decimal.Equals(Object)The equivalent method for this operator is Decimal.Equals(Object)
