public enum MenuOption
{
TestName = 0,
GuessThatNumber = 1,
Quit = 2,
}
public class Program
{
static TestName()
{
string name;
Console.WriteLine("Please Enter Your Name" + name);
Console.WriteLine("Hello " + name);
}
private static MenuOption ReadUserOption()
{
int option;
Console.WriteLine("1 Will run test name, 2 Will play guess that number, 3 Will quit ");
do
{
Console.Write("Choose an option [1-3]: ");
option = Convert.ToInt32(Console.ReadLine());
} while (option <0 || option >4);
return (MenuOption)(option -1);
}
public static void Main()
{
MenuOption userSelection;
do
{
userSelection = ReadUserOption();
Console.WriteLine(userSelection);
switch(userSelection)
{
case MenuOption.TestName:
TestName();
break;
case MenuOption.GuessThatNumber:
Console.WriteLine("GuessThatNumber...");
