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

參數

type
Type

要移除的註解類型。

範例

以下範例建立一個元素，上面有四個註解。 接著用這個方法移除其中兩個。

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

此範例會產生下列輸出：

Count before removing: 4
Count after removing: 2
