'Declaration
Public Sub RemoveAnnotations ( _
type As Type _

public void RemoveAnnotations(
Type type
)
Parameters

Examples
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
public class MyAnnotation
{
private string tag;
public string Tag { get { return tag; } set { tag = value; } }
public MyAnnotation(string tag)
{
this.tag = tag;
}
}
The following example creates an element with four annotations on it. It then uses this method to remove two of them.
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")
output.Append("Count before removing: {0}", root.Annotations(Of Object)().Count())
output.Append(Environment.NewLine)
root.RemoveAnnotations(GetType(MyAnnotation))
output.Append("Count after removing: {0}", root.Annotations(Of Object)().Count())
output.Append(Environment.NewLine)
OutputTextBlock.Text = output.ToString()
StringBuilder output = new StringBuilder();
XElement root = new XElement("Root", "content");
root.AddAnnotation(new MyAnnotation("T1"));
root.AddAnnotation(new MyAnnotation("T2"));
root.AddAnnotation("abc");
root.AddAnnotation("def");
output.Append("Count before removing: " + root.Annotations<object>().Count() + Environment.NewLine);
root.RemoveAnnotations(typeof(MyAnnotation));
output.Append("Count after removing: " + root.Annotations<object>().Count() + Environment.NewLine);
OutputTextBlock.Text = output.ToString();
