If you now run this updated application, you will find that the methods of a given type are

much more detailed. Figure 16-3 shows the method metadata of the System.Globalization.

Method details of System.Globalization.GregorianCalendar

The current implementation of ListMethods() is helpful, in that you can directly investigate

each parameter and method return value using the System.Reflection object model. As an extreme

shortcut, be aware that each of the XXXInfo types (MethodInfo, PropertyInfo, EventInfo, etc.) have

overridden ToString() to display the signature of the item requested. Thus, we could also imple-

ment ListMethods() as follows:

public static void ListMethods(Type t)

{

Console.WriteLine("***** Methods *****");

MethodInfo[] mi = t.GetMethods();

foreach (MethodInfo m in mi)

{

// Could also simply say "Console.WriteLine(m)" as well,

// as ToString() is called automatically by WriteLine().
