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