IEqualityComparer<T>.Equals Method

Determines whether the specified objects are equal.

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

bool Equals(
	T x,
	T y
)

Parameters

x
Type: T

The first object of type T to compare.

y
Type: T

The second object of type T to compare.

Return Value

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

Implement this method to provide a customized equality comparison for type T.

Notes to Implementers

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.

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.
