'Declaration
Public Function Annotations ( _
	type As Type _
) As IEnumerable(Of Object)

Parameters

type
Type: System.Type
The Type of the annotations to retrieve.

Return Value

Type: System.Collections.Generic.IEnumerable(Of Object)
An IEnumerable(Of T) of Object that contains the annotations that match the specified type for this XObject.

The following class is used in the example below:


Dim output As New StringBuilder
Dim doc As XDocument = _
        <?xml version="1.0"?>
        <!--A comment in the document.-->
        <Root>
            <Child>content</Child>
        </Root>
Dim child As XElement = doc.Descendants("Child").First()
Dim documentOfChild As XDocument = child.Document
output.Append(documentOfChild.FirstNode)
output.Append(Environment.NewLine)

OutputTextBlock.Text = output.ToString()


The following example adds some annotations to an XElement, then retrieves a collection of annotations by using this method.


Dim output As New StringBuilder
Dim root As XElement = <Root>content</Root>
root.AddAnnotation(New MyAnnotation("T1"))
root.AddAnnotation(New MyAnnotation("T2"))
root.AddAnnotation("abc")
root.AddAnnotation("def")

Dim annotationList As IEnumerable(Of Object)
annotationList = root.Annotations(GetType(MyAnnotation))
For Each ma As MyAnnotation In annotationList
    output.Append(ma.Tag)
    output.Append(Environment.NewLine)
Next

output.Append("----")
output.Append(Environment.NewLine)

Dim stringAnnotationList As IEnumerable(Of Object)
stringAnnotationList = root.Annotations(GetType(String))
For Each str As String In stringAnnotationList
    output.Append(str)
    output.Append(Environment.NewLine)
Next

OutputTextBlock.Text = output.ToString()
