Equality comparer interface


Required Methods

constructor    (declared in Object)

Default constructor.










Sub New()

Equals (Object): Boolean  virtual    (declared in Object)

Returns true if the target object matches this one, by default compares the reference.


method Equals(obj: Object): Boolean


Boolean Equals(Object obj)


func Equals(_ obj: Object) -> Boolean


Boolean Equals(Object obj)


Function Equals(obj As Object) As Boolean


  • obj: the reference to compare this with.

Equals (T, T): Boolean

Equals operator; should return true if both values are the same.


method Equals(x: T; y: T): Boolean


Boolean Equals(T x, T y)


func Equals(_ x: T, _ y: T) -> Boolean


Boolean Equals(T x, T y)


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


  • x:
  • y:

Finalize  protected virtual    (declared in Object)

Finalizer implementation. If not overriden it's not called at all, the runtime checks if there is an override before calling a finalizer.


method Finalize


void Finalize()


func Finalize()


void Finalize()


Sub Finalize()

GetHashCode  virtual    (declared in Object)

Returns a hashcode for this object. Overriden implementations should make sure that the number returned here is constant given the same object.


method GetHashCode: Int32


Int32 GetHashCode()


func GetHashCode() -> Int32


Int32 GetHashCode()


Function GetHashCode() As Int32

GetHashCode (T): Int32

Gets a hash of this value.


method GetHashCode(obj: T): Int32


Int32 GetHashCode(T obj)


func GetHashCode(_ obj: T) -> Int32


Int32 GetHashCode(T obj)


Function GetHashCode(obj As T) As Int32


  • obj:

GetType    (declared in Object)

Returns the actual type of this class


method GetType: Type


Type GetType()


func GetType() -> Type


Type GetType()


Function GetType() As Type

ToString  virtual    (declared in Object)

Gets the string representation of this method.


method ToString: String


String ToString()


func ToString() -> String


String ToString()


Function ToString() As String

ReferenceEquals    (declared in Object)

Compares two references for equivalence (even if they have an equals operator)


class method ReferenceEquals(a: Object; b: Object): Boolean


static Boolean ReferenceEquals(Object a, Object b)


static func ReferenceEquals(_ a: Object, _ b: Object) -> Boolean


static Boolean ReferenceEquals(Object a, Object b)


Shared Function ReferenceEquals(a As Object, b As Object) As Boolean


  • a: left value
  • b: right value
