If you put an attribute Foobar on a class or class member then code
accessing your code via reflection can use the information from the
attribute to change what it will do with your code.

If you put an attribute Foobar on a class or class member then code
accessing your code via reflection can use the information from the
attribute to change what it will do with your code.

Example:

using System;
using System.Xml.Serialization;

namespace E
{
public class UglyName
{
}
[XmlRoot(ElementName="this-is-a-nice-name")]
public class AnotherUglyName
{
}
public class Program
{
public static void Main(string[] args)
{
(new XmlSerializer(typeof(UglyName))).Serialize(Console.Out, new
UglyName());
Console.WriteLine();
(new XmlSerializer(typeof(AnotherUglyName))).Serialize(Console.Out,
new AnotherUglyName());
Console.ReadKey();
}
}
}
