c# - Number Guessing Game: difficulty setting -

-

this how generating random number, able have user select difficulty: easy = 1-10, intermediate = 1-50, hard = 1-100. wondering how done. appreciated. 

{     class hilow     {         private int number;          public int number         {                         {                 return number;             }         }          public hilow(int taker)         {             number = new random().next(taker);         }     } }  {     class hilowui     {         public void welcome()         {             console.writeline("\nwelcome highlow game!" +                 "\n\ninstructions: \ntry guess number between selected difficulty range." +                  "\nif guess right number win!");              console.writeline("\ndifficulty: \n[1] (1-10) easy \n[2] (1-50) intermediate \n[3] (1-100) hard");          }         public void play()         {             welcome();              while (true)             {                 hilow hi = null;                 int number = hi.number;                 int guess;                 int attempts = 0;                  int difficulty = promptforint("select difficulty");                 if (difficulty == 1)                 {                    hi = new hilow(10);                 }                 else if (difficulty == 2)                 {                     hi = new hilow(50);                 }                 else if (difficulty == 3)                 {                     hi = new hilow(100);                 }                  (guess = promptforint("\nenter guess! "); guess != number; guess = promptforint("\nenter guess! "))                 {                     if (guess < number)                     {                         console.writeline("higher");                         attempts++;                     }                     else if (guess > number)                     {                         console.writeline("lower");                         attempts++;                     }                 }                 console.writeline("\nit took {0} attempts, you've won!\n{1} correct number!\n", attempts, number);                 console.writeline("would play again? (y/n)");                  if (console.readline() != "y") break;             }         }         private int promptforint(string prompt)         {             int value;             console.write(prompt);             int.tryparse(console.readline(), out value);             return value;         }     } }

when have user's setting, add option constructor of hilow maximum number. use number generating random number.
