Microsoft Silverlight will reach end of support after October 2021. Learn more.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public Function Equals ( _
o As Type _
) As Boolean
public bool Equals(
Type o
)
Parameters
- o
Type: System.Type
The Type 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.
Examples
The following example uses Equals to compare two types.

Class Example
Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
Dim a As Type = GetType(System.String)
Dim b As Type = GetType(System.Int32)
outputBlock.Text += String.Format("{0} = {1}: {2}", a, b, a.Equals(b)) & vbCrLf
' The Type objects in a and b are not equal,
' because they represent different types.
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(Type)
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 Type.
'Console.ReadLine()
End Sub
End Class

' This code example produces the following output:
' System.String = System.Int32: False
' Example is equal to Example: True
' typeof(Example).Equals(typeof(System.Type)): False
