Implementing Main()

The Main() method of the Program class prompts the user for the fully qualified name of a type.

Once you obtain this string data, you pass it into the Type.GetType() method and send the extracted

System.Type into each of your helper methods. This process repeats until the user enters Q to termi-

nate the application:

static void Main(string[] args)

{

Console.WriteLine("***** Welcome to MyTypeViewer *****");

string typeName = "";

bool userIsDone = false;

do

{

Console.WriteLine("\nEnter a type name to evaluate");

Console.Write("or enter Q to quit: ");

// Get name of type.

typeName = Console.ReadLine();

// Does user want to quit?

if (typeName.ToUpper() == "Q")

{

userIsDone = true;

break;

}

// Try to display type.

try

{

Type t = Type.GetType(typeName);

Console.WriteLine("");

ListVariousStats(t);

ListProps(t);

ListMethods(t);

ListInterfaces(t);

}

catch

{

Console.WriteLine("Sorry, can't find type");

}

} while (!userIsDone);

}

At this point, MyTypeViewer.exe is ready to take out for a test drive. For example, run your appli-

cation and enter the following fully qualified names (be aware that the manner in which you invoked

Type.GetType() requires case-sensitive string names):

• System.Int32

• System.Collections.ArrayList

• System.Threading.Thread

• System.Void

• System.IO.BinaryWriter

• System.Math

• System.Console

• MyTypeViewer.Program

Figure 16-2 shows the partial output when specifying System.Math.
