    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);
    }
}

This example produces the following output:


                T1
