check if there item exist in the list c#

Question

I have game app that has 5 items with description and price. after I display description user guess the price and this item goes to to previous guesses list. When I am looping through my game and user finishes it, I want the console to ask user again if he want to play. In that case i don't want to show the item twice, meaning i need to make sure that I never show the product twice.

first things first: edit your code so we get a working example. the part you show so far does not even compile when looked at. once this is established we can discuss scope, for example of guessedProducts which should certainly be declared before the program enters the game loop. — Cee McSharpface

This isn't even close to compiling. Your missing braces, you have a switch inside of a case that isn't inside of a switch... Honestly, at least try — AustinWBryan

+1 because I'm tired of the stupid downvote police scaring away new users. There was a really great blog post on meta about exactly this sort of thing recently. — 3Dave

game.Start() gives you next Question ? and where are you adding things in game.PreviousGuesses ? — Amit

From what i can tell, you need to simply skip the loop with an if statement. You need to declare and initialize a bool before your game loop and update it if the player chooses to retry

bool retry = false
...

   if(!retry)
      foreach (var p in guessedProducts)
      {
         Console.Write(p.ToString() + "\r\n");
      }
...
   if(choice == 1)
   {
      retry = true
   }

I added retry = true as well as this: retry = true; Console.Write("Gueess the price of the product: "); nextProduct = game.Start().Description; Console.WriteLine("Description: " + nextProduct); I get it working except that incrementing my guesses should only apply per item, and its incrementing all of them together, Do you know by any chance how to fix that?

Sorry for late reply.Sadly i cannot see the original code anymore but if you simply add an array or list with separate int's to increment it should solve the problem.
