Reflecting on Methods

The Program class will be updated to define a number of static methods, each of which takes a single

System.Type parameter and returns void. First you have ListMethods(), which (as you might guess)

prints the name of each method defined by the incoming type. Notice how Type.GetMethods()

returns an array of System.Reflection.MethodInfo types:

// Display method names of type.

static void ListMethods(Type t)

{

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

MethodInfo[] mi = t.GetMethods();

foreach(MethodInfo m in mi)

Console.WriteLine("->{0}", m.Name);

Console.WriteLine();

}

Here, you are simply printing the name of the method using the MethodInfo.Name property. As

you might guess, MethodInfo has many additional members that allow you to determine whether

the method is static, virtual, generic, or abstract. As well, the MethodInfo type allows you to obtain

the method’s return value and parameter set. You’ll spruce up the implementation of ListMethods()

in just a bit.
