Microsoft Silverlight will reach end of support after October 2021. Learn more.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Overrides Function Equals ( _
o As Object _
) As Boolean
public override bool Equals(
Object o
)
Parameters
- o
Type: System.Object
The Object whose underlying system type is to be compared with the underlying system type of the current Type.
Return Value
Type: System.Boolean
true if the underlying system type of o is the same as the underlying system type of the current Type; otherwise, false. This method also returns false if the object specified by the o parameter is not a Type.
Examples
The following example uses Equals to compare two Object instances.

Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim a As Type = GetType(System.Object)
Dim b As Type = GetType(System.Object)
outputBlock.Text += String.Format("{0} = {1}: {2}", a, b, a.Equals(b)) & vbCrLf
' The Type objects in a and b are equal,
' because they represent System.Object.
a = GetType(Example)
b = New Example().GetType()
outputBlock.Text += String.Format("{0} is equal to {1}: {2}", a, b, a.Equals(b)) & vbCrLf
' The Type objects in a and b are equal,
' because they both represent type Example.
b = GetType([Object])
outputBlock.Text += String.Format("typeof({0}).Equals(typeof({1})): {2}", a, b, a.Equals(b)) & vbCrLf
' The Type objects in a and b are not equal,
' because variable a represents type Example
' and variable b represents type Object.
'Console.ReadLine();
End Sub
End Class

' This code example produces the following output:
' System.Object = System.Object: True
' Example is equal to Example: True
