RemoveAnnotations(Type)

從這個 XObject 中移除指定之類型的註釋。Removes the annotations of the specified type from this XObject.

RemoveAnnotations<T>()

從這個 XObject 中移除指定之類型的註釋。Removes the annotations of the specified type from this XObject.

RemoveAnnotations(Type)

從這個 XObject 中移除指定之類型的註釋。Removes the annotations of the specified type from this XObject.

public:
 void RemoveAnnotations(Type ^ type);
public void RemoveAnnotations (Type type);
member this.RemoveAnnotations : Type -> unit

參數

type
Type

要移除的註釋類型。The type of annotations to remove.

範例

下列範例會在其上建立具有四個注釋的元素。The following example creates an element with four annotations on it. 然後,它會使用這個方法來移除其中兩個。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  

這個範例會產生下列輸出:This example produces the following output:

Count before removing: 4  
Count after removing: 2
