ReadLine() method is used to take line of text form console and return string. When user press Enter key then it returns string. ReadKey() method takes a single character and return values of ConsoleKeyInfo structure. This struct describes console key that was pressed and it also gives the state of modifier keys like SHIFT,CTRL,ALT. class Program { static void Main(string[] args) { string s; s= Console.ReadLine(); Console.WriteLine(s); ConsoleKeyInfo k = Console.ReadKey(); Console.WriteLine(k.KeyChar ); Console.WriteLine(k.Key); Console.WriteLine(k.Modifiers ); Console.ReadKey(); } }

If you declare a field to be 'readonly' then you can only assign a value to it either when it's declared or from a constructor. You are therefore prevented from assigning a different value to it at a later stage. Check the example in MSDN: http://msdn.microsoft.com/en-us/library/acdd6hb7.aspx
