EqualityComparer<T>.Equals(T, T) Method

Definition

Namespace:

System.Collections.Generic

Assembly:

System.Collections.dll

Source:

EqualityComparer.CoreCLR.cs

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

public:
 abstract bool Equals(T x, T y);

public abstract bool Equals (T? x, T? y);

override this.Equals : 'T * 'T -> bool

Public MustOverride Function Equals (x As T, y As T) As Boolean

Parameters

x

T

The first object to compare.

y

T

The second object to compare.

Returns

Boolean

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

Implements

Equals(T, T)

Remarks

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 Implementers

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