EqualityComparer<T>.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
)

Parameters

x
Type: T

The first object to compare.

y
Type: T

The second object to compare.

Return Value

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

Implements

IEqualityComparer<T>.Equals(T, T)

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.
