Microsoft Silverlight will reach end of support after October 2021. Learn more.

The HideModuleNameAttribute attribute, when applied to a module, allows the module members to be accessed using only the qualification needed for the module.

Remarks

This attribute is useful for exposing module members without showing the module itself. When using IntelliSense in the Visual Studio Integrated Development Environment (IDE) for Visual Basic, the module does not show in the statement completion list. Instead, IntelliSense shows the module members.

Even when the module name is hidden, the module members are still accessible through the module.

If a member name conflicts with another identifier or with a member of another module with the HideModuleNameAttribute attribute, then the member does not show in IntelliSense at the level of the module.

Examples

This example shows how to use the HideModuleNameAttribute attribute to add a Database object to My, which can be accessed through My.Database.

Namespace My
  <HideModuleName()> Module CustomMyDatabase
    Public ReadOnly Property Database() As MyDatabase
      Get
        Return databaseValue
      End Get
    End Property
    Private ReadOnly databaseValue As MyDatabase = New MyDatabase
  End Module
End Namespace

Class MyDatabase
  ' The members of the My.Database object go here.
End Class

The Namespace statement must appear outside of any classes or modules.
