Indicates whether this instance and a specified object are equal.
(in mscorlib.dll)
'Usage
Dim instance As ValueType
Dim obj As Object
Dim returnValue As Boolean
returnValue = instance.Equals(obj)
'Declaration
Public Overrides Function Equals ( _
obj As Object _
) As Boolean
Return Value
Type:
System..::.Boolean
true if obj and this instance are the same type and represent the same value; otherwise, false.
The default implementation of the Equals method uses reflection to compare the corresponding fields of obj and this instance. Override the Equals method for a particular type to improve the performance of the method and more closely represent the concept of equality for the type.
The following example demonstrates how the Equals method can be overridden by a derived value type.
Public Structure Complex
Private m_Re As Double
Private m_Im As Double
Public Overloads Function Equals(ob As Object) As Boolean
If TypeOf ob Is Complex Then
Dim c As Complex = CType(ob, Complex)
Return m_Re = c.m_Re And m_Im = c.m_Im
Else
Return False
End If
End Function
Public Overloads Function GetHashCode() As Integer
Return m_Re.GetHashCode() ^ m_Im.GetHashCode()
End Function
