Type.IsVisible Property

Gets a value indicating whether the Type can be accessed by code outside the assembly.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public ReadOnly Property IsVisible As Boolean

Property Value

Type: System.Boolean
true if the current Type is a public type or a public nested type such that all the enclosing types are public; otherwise, false.

Use this property to determine whether a type is part of the public interface of a component assembly.

The following code example tests two classes, only one of which is visible outside the assembly.


Imports System

Friend Class InternalOnly
    Public Class Nested
    End Class
End Class

Public Class Example
    Public Class Nested
    End Class

    Public Shared Sub Main()
        With GetType(InternalOnly.Nested)
            Console.WriteLine("Is the " & .FullName _ 
                & " class visible outside the assembly? " & .IsVisible)
        End With

        With GetType(Example.Nested)
            Console.WriteLine("Is the " & .FullName _ 
                & " class visible outside the assembly? " & .IsVisible)
        End With
    End Sub
End Class

' This example produces the following output:
'
'Is the InternalOnly+Nested class visible outside the assembly? False
'Is the Example+Nested class visible outside the assembly? True
