Annotations(Type)
public:
System::Collections::Generic::IEnumerable<System::Object ^> ^ Annotations(Type ^ type);
public System.Collections.Generic.IEnumerable<object> Annotations (Type type);
member this.Annotations : Type -> seq<obj>
Public Function Annotations (type As Type) As IEnumerable(Of Object)
Parâmetros
- type
- Type
O tipo das anotações a serem recuperadas.The type of the annotations to retrieve.
Retornos
Um IEnumerable<T> de Object que contém as anotações que correspondem ao tipo especificado para este XObject.An IEnumerable<T> of Object that contains the annotations that match the specified type for this XObject.
Exemplos
O exemplo a seguir adiciona algumas anotações a um XElement e, em seguida, recupera uma coleção de anotações usando esse método.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
Esse exemplo gera a saída a seguir:This example produces the following output:
