EqualityComparer.Equals Method (T, T)

When overridden in a derived class, determines whether two objects of type T are equal.

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

public abstract bool Equals (
	T x,
	T y
public abstract boolean Equals (
	T x, 
	T y
public abstract function Equals (
	x : T, 
	y : T
) : boolean
Not applicable.



The first object to compare.


The second object to compare.

Return Value

true if the specified objects are equal; otherwise, false.

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.

Notes to Inheritors: 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.
