定义

重载

RemoveAnnotations(Type)

从此 XObject 移除指定类型的批注。Removes the annotations of the specified type from this XObject.

RemoveAnnotations<T>()

从此 XObject 移除指定类型的批注。Removes the annotations of the specified type from this XObject.

RemoveAnnotations(Type)

从此 XObject 移除指定类型的批注。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

参数

type
Type

要移除的批注的类型。The type of annotations to remove.

示例

下面的示例创建一个具有四个批注的元素。The following example creates an element with four annotations on it. 然后,它使用此方法删除其中的两个。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  

该示例产生下面的输出:This example produces the following output:

Count before removing: 4  
Count after removing: 2
