Interesting OOPS puzzle [closed]

Question

Recently, I faced the below question in an interview. Initially I thought that the question was wrong, but the interviewer mentioned there is a solution for this. Given this class:

public class BaseHome {     public static void Main()     {         Console.WriteLine("A");     } } 

Write the following to the console:

B A C 

Rules:

1. Do not change the Main function.
2. Do not create any additional classes.

How can this be done?

Answer 1

Assuming you meant B A C on three lines (plus no typo on main method name):

namespace ConsoleApplication1 {     public class BaseHome     {         static BaseHome()         {             Console.WriteLine("B");              AppDomain.CurrentDomain.ProcessExit += new EventHandler(OnProcessExit);         }          public static void Main()         {             Console.WriteLine("A");         }          private static void OnProcessExit(object sender, EventArgs e)         {             Console.WriteLine("C");             Console.Read();         }     } } 

Answer 2

Hahaha, I figured it out. Create a static property!

public class BaseHome {     public static void Main()     {        Console.WriteLine("A");     }      public static BaseHome Console     {         get{ return new BaseHome(); }     }      public void WriteLine(string s) {         System.Console.WriteLine("BCA"); //Or multiple lines if you like     }  } 

Edit: Or, duh, just a field

public class BaseHome {     static BaseHome Console = new BaseHome();      public static void Main()     {        Console.WriteLine("A");     }      public void WriteLine(string s) {         System.Console.WriteLine("BCA"); //Or multiple lines if you like     }  }
