'Declaration
Public Sub AddAnnotation ( _
	annotation As Object _
)

Parameters

annotation
Type: System.Object
An Object that contains the annotation to add.

Note that annotations are not part of the infoset; they are not persisted, or displayed by ToString.

The following class is used in the example below:


Public Class MyAnnotation
    Private _tag As String

    Property Tag() As String
        Get
            Return Me._tag
        End Get
        Set(ByVal Value As String)
            Me._tag = Value
        End Set
    End Property

    Public Sub New(ByVal tag As String)
        Me._tag = tag
    End Sub
End Class


The following example adds an annotation to an XElement.


Dim output As New StringBuilder
Dim ma As MyAnnotation = New MyAnnotation("T1")
Dim root As XElement = <Root>content</Root>
root.AddAnnotation(ma)

Dim ma2 As MyAnnotation = DirectCast(root.Annotation(Of MyAnnotation)(), MyAnnotation)
output.Append(ma2.Tag)
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()
