)

Return Value

Type: System.Object
The Object that contains the first annotation object that matches the specified type, or null if no annotation is of the specified type.

The following example adds an annotation to an XElement. It then retrieves the annotation, specifying the type to retrieve.

public class MyAnnotation {
    private string tag;
    public string Tag {get{return tag;} set{tag=value;}}
    public MyAnnotation(string tag) {
        this.tag = tag;
    }
}

public class Program {
    public static void Main(string[] args) {   
        MyAnnotation ma = new MyAnnotation("T1");
        XElement root = new XElement("Root", "content");
        root.AddAnnotation(ma);

        MyAnnotation ma2 = (MyAnnotation)root.Annotation(typeof(MyAnnotation));
        Console.WriteLine(ma2.Tag);
    }
}

This example produces the following output:
