Typ adnotacji do usunięcia.The type of annotations to remove.

Przykłady

Poniższy przykład tworzy element z czterema adnotacjami.The following example creates an element with four annotations on it. Następnie używa tej metody do usuwania dwóch z nich.It then uses this method to remove two of them.

public class MyAnnotation {  
    private string tag;  
    public string Tag {get{return tag;} set{tag=value;}}  
    public MyAnnotation(string tag) {  
        this.tag = tag;  
    }  
}  
  
class Program  
{  
    static void Main(string[] args)  
    {     
        XElement root = new XElement("Root", "content");  
        root.AddAnnotation(new MyAnnotation("T1"));  
        root.AddAnnotation(new MyAnnotation("T2"));  
        root.AddAnnotation("abc");  
        root.AddAnnotation("def");  
  
        Console.WriteLine("Count before removing: {0}", root.Annotations<object>().Count());  
        root.RemoveAnnotations(typeof(MyAnnotation));  
        Console.WriteLine("Count after removing: {0}", root.Annotations<object>().Count());  
    }  
}  
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  
  
Module Module1  
    Sub Main()  
        Dim root As XElement = <Root>content</Root>  
        root.AddAnnotation(New MyAnnotation("T1"))  
        root.AddAnnotation(New MyAnnotation("T2"))  
        root.AddAnnotation("abc")  
        root.AddAnnotation("def")  
  
        Console.WriteLine("Count before removing: {0}", root.Annotations(Of Object)().Count())  
        root.RemoveAnnotations(GetType(MyAnnotation))  
        Console.WriteLine("Count after removing: {0}", root.Annotations(Of Object)().Count())  
    End Sub  
End Module  

Ten przykład generuje następujące wyniki:This example produces the following output:

Count before removing: 4  
Count after removing: 2
