AddAnnotation(ano1);
textBox1.Text = root.ToString();
TestAnnotation ano2 = root.Annotation();
textBox1.Text = ano2.Val1.ToString();
When you run this code, the text box should display the value 500.

Of course, annotations can be of any type, so the preceding code could simply have been written
as follows:
XElement root = new XElement("Root", "scott");
root.AddAnnotation(500);
What happens if you want to add an annotation of another type? Fortunately, you don??™t need to create
a new annotation class. The following is an example that uses the same original annotation class to add
another annotation type of string, as shown by the highlighted code. It does that by creating a new public
method of the same name as the original method:
public class TestAnnotation
{
private int val1;
private string val2;
public int Val1 { get { return val1;} set { val1 = value;}}
public string Val2 { get { return val2;} set { val2 = value;}}
public TestAnnotation(int val1)
{
this.
