# Decimal.Equals Method (Decimal, Decimal)

Returns a value indicating whether two specified instances of Decimal represent the same value.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

## Syntax

``````'Declaration
<SecuritySafeCriticalAttribute> _
Public Shared Function Equals ( _
d1 As Decimal, _
d2 As Decimal _
) As Boolean
``````
``````[SecuritySafeCriticalAttribute]
public static bool Equals(
decimal d1,
decimal d2
)
``````

#### Return Value

Type: System.Boolean
true if d1 and d2 are equal; otherwise, false.

## Examples

The following code example compares several Decimal values to a reference Decimal value using the static Decimal.Equals(Decimal, Decimal) method.

``````' Example of the Decimal.Compare and static Decimal.Equals methods.

Module Example

Const dataFmt As String = "{0,-45}{1}"

' Compare Decimal parameters, and display them with the results.
Sub CompareDecimals(ByVal outputBlock As System.Windows.Controls.TextBlock, ByVal Left As Decimal, ByVal Right As Decimal, _
ByVal RightText As String)

outputBlock.Text &= vbCrLf
outputBlock.Text += String.Format(dataFmt, "Right: " & RightText, Right) & vbCrLf
outputBlock.Text += String.Format(dataFmt, "Decimal.Equals( Left, Right ) & vbCrLf", _
Decimal.Equals(Left, Right))
outputBlock.Text += String.Format(dataFmt, _
"Decimal.Compare( Left, Right )", _
Decimal.Compare(Left, Right)) + vbCrLf
End Sub
