Picking the 3 first players from a Dictionary

Hello guys,

I made this multiplayer game where up to 4 players can compete hunting fish. I have a dictionary that contains the players name as keys and the score as values. When the time runs out, I want to be able to show what players are the first, second, and third places.

Can someone here, help me to figure out how to sort, or compare, the values in the dictionary so I can select each player who won any of those places?

I have google this without any good results.

Regards,
Carlos

 

Steps:

1. get something that represents player (something that contains their score) into an array of the number you want to sort (3 in the case you listed)

2. use Array.Sort() to sort the array, supplying a comparison delegate that compares the scores.

https://docs.microsoft.com/en-us/dotnet/api/system.array.sort?view=netcore-3.1

 

A Dictionary is not an ordered collection and can't really be sorted. However you can get the KeyValuePairs it contains as an array or List and just sort that.

Code (CSharp):

1.  
2.         Dictionary<string, int> playerScores = new Dictionary<string, int>();
3.         // copy all KeyValuePairs into a List
4.         var list = new List<KeyValuePair<string, int>>(playerScores);
5.         // Sort them based on the "Value"
6.         list.Sort((a,b)=>a.Value.CompareTo(b.Value));
7.  

 

Hello guys,

Thank you for your reply!
