'Declaration
Public Function Annotation ( _
	type As Type _
) As Object

Parameters

Type: System.Type
The Type of the annotation to retrieve.

Return Value

Type: System.Object
The Object that contains the first annotation object that matches the specified type, or Nothing if no annotation is of the specified type.

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. It then retrieves the annotation, specifying the type to retrieve.


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(GetType(MyAnnotation)), MyAnnotation)
output.Append(ma2.Tag)
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()
