public:
void RemoveAnnotations(Type ^ type);
C#
public void RemoveAnnotations (Type type);
member this.RemoveAnnotations : Type -> unit
Public Sub RemoveAnnotations (type As Type)
參數
- type
- Type
要移除的註釋類型。
範例
下列範例會建立具有四個批註的專案。 然後,它會使用這個方法來移除其中兩個方法。
C#
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:
Count before removing: 4
Count after removing: 2
