How to keep console window open

Question

When I run my program, the console window seems to run and close. How to keep it open so I can see the results?

class Program {     public class StringAddString            {                                 public virtual void AddString()         {             var strings2 = new string[] { "1", "2", "3", "4", "5","6", "7", "8", "9"};              Console.WriteLine(strings2);             Console.ReadLine();         }     }      static void Main(string[] args)     {                   StringAddString s = new StringAddString();                 } } 

Answer 1

Put a Console.Read() as the last line in your program. That will prevent it from closing until you press a key

static void Main(string[] args) {     StringAddString s = new StringAddString();     Console.Read();             }
