Type

Typ adnotacji do pobrania.The type of the annotations to retrieve.

Zwraca

Elementu zawierającego adnotacje, które pasują do określonego typu XObject. IEnumerable<T> ObjectAn IEnumerable<T> of Object that contains the annotations that match the specified type for this XObject.

Przykłady

Poniższy przykład dodaje adnotacje do XElement, a następnie pobiera kolekcję adnotacji przy użyciu tej metody.The following example adds some annotations to an XElement, then retrieves a collection of annotations by using this method.

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");  
  
        IEnumerable<object> annotationList;  
        annotationList = root.Annotations(typeof(MyAnnotation));  
        foreach (object ma in annotationList)  
            Console.WriteLine(((MyAnnotation)ma).Tag);  
        Console.WriteLine("----");  
  
        IEnumerable<object> stringAnnotationList;  
        stringAnnotationList = root.Annotations(typeof(string));  
        foreach (object str in stringAnnotationList)  
            Console.WriteLine((string)str);  
    }  
}  
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")  
  
        Dim annotationList As IEnumerable(Of Object)  
        annotationList = root.Annotations(GetType(MyAnnotation))  
        For Each ma As MyAnnotation In annotationList  
            Console.WriteLine(ma.Tag)  
        Next  
  
        Console.WriteLine("----")  
  
        Dim stringAnnotationList As IEnumerable(Of Object)  
        stringAnnotationList = root.Annotations(GetType(String))  
        For Each str As String In stringAnnotationList  
            Console.WriteLine(str)  
        Next  
    End Sub  
End Module
