C# Unity How to print out a dictionary in order-CodePudding

How can I manage to do something like this

` Heli Takedown >

playername | 10

playername | 19

playername | 23 etc.. `

I am storing the Player and damage done in a dictionary, just finding it hard to take it all out and then print it into a message and only print the top 5 players who did the most damage. Code:

        private void SendHeliMessage()
        {
            foreach (KeyValuePair<BasePlayer, int> hitInfo in HeliHits)
            {
                BasePlayer Player = hitInfo.Key;
                int DamageDone = hitInfo.Value;
                var players = HeliHits.Keys;
                SendMessage(Player,$"this is a test, Heli Takedown >\n\n{0} | {1}", null, 0, Player.displayName, string.Join("\n", DamageDone));
            }
        }
        void SendMessage(BasePlayer player, string message, params object[] args)
        {
            PrintToChat(player, message, args);
        }

(Yes i know what I have is wrong it was me just messing around and testing)

To sort the dictionary by Value from highest to lowest may look something like…

var sorted = HeliHits.OrderByDescending(key => key.Value);

Then to loop through the dictionary and output all the Key Value pairs may look something like…

foreach (KeyValuePair<BasePlayer, int> hitInfo in sorted) {
    SendMessage(hitInfo.Key, $"this is a test, Heli Takedown >\n\n{0} | {1}", hitInfo.Key.displayName, string.Join("\n", hitInfo.Value));
}

If you wanted only the top 5 values in the dictionary then you could do something like….

var sorted = HeliHits.OrderByDescending(key => key.Value).Take(5);

Sorry for not seeing the obvious initially. A dictionary is by design unordered, but of course you can iterate over it in a ordered way by explicitly requesting an ordered enumeration:

private void SendHeliMessage()
        {
            foreach (KeyValuePair<BasePlayer, int> hitInfo in HeliHits.OrderByDescending(x => x.Value)) // Get players with their score ordered from the best to the worst
            {
                BasePlayer Player = hitInfo.Key;
                int DamageDone = hitInfo.Value;
                var players = HeliHits.Keys;
                SendMessage(Player, $"this is a test, Heli Takedown >\n\n{0} | {1}", null, 0, Player.displayName, string.Join("\n", DamageDone));
            }
        }

To get a single message:

   private void SendHeliMessage()
        {
            StringBuilder result = new StringBuilder();
            int rank = 1;
            foreach (KeyValuePair<BasePlayer, int> hitInfo in HeliHits.OrderByDescending(x => x.Value)) // Get players with their score ordered from the best to the worst
            {
                BasePlayer Player = hitInfo.Key;
                int DamageDone = hitInfo.Value;
                var players = HeliHits.Keys;
                result.Append($"Rank {rank}: Player {Player.displayName} with {DamageDone} points");
                rank  ;
            }
            SendMessage(Player, result.ToString(), null, 0, Player.displayName, string.Empty);
        }
