IEqualityComparer.Equals Method

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Determines whether the specified objects are equal.

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

'Declaration
Function Equals ( _
	x As Object, _
	y As Object _
) As Boolean

Parameters

x
Type: System.Object
The first object to compare.
y
Type: System.Object
The second object to compare.

Return Value

Type: System.Boolean
true if the specified objects are equal; otherwise, false.

ExceptionCondition
ArgumentException

x and y are of different types and neither one can handle comparisons with the other.

Implement this method to provide a customized equality comparison for objects.

Notes to Implementers

The Equals method is reflexive, symmetric, and transitive. That is, it returns true if used to compare an object with itself; true for two objects x and y if it is true for y and x; and true for two objects x and z if it is true for x and y and also true for y and z.

Implementations are required to ensure that if the Equals method returns true for two objects x and y, then the value returned by the GetHashCode method for x must equal the value returned for y.
