如何在c＃中顯示數組的最大值，最小值和平均值？

Question

基本上我必須編寫一個程序，要求用戶列出他們球隊的球員名單，列出他們的名字以及他們得分的進球數。輸出結果應該是「最高的球員是...得分..平均進球數是..最低進球數是..」

我們還沒有真正覆蓋陣列，但我有現在開始了這個問題，它會讓我瘋狂，直到完成。我知道我可能會遠離獲得我所需要的東西，但任何一點正確的方向都會非常感謝！ P.S我知道我的代碼的最後一點是完全錯誤的，我只是不知道從哪裏去。我的代碼：

Console.WriteLine("Enter the amount of players"); 
    int amount = int.Parse(Console.ReadLine()); 

    string[] names = new string[amount]; 
    int[] playerGoals = new int[amount]; 
    int result; 
    string playerName; 

    for (int i = 0; i < playerGoals.Length; i++) 
    { 
     Console.WriteLine("Enter a players name"); 
     playerName = Console.ReadLine(); 
     names[i] = playerName; 

     Console.WriteLine("Enter how many goals they have score this season"); 
     result = int.Parse(Console.ReadLine()); 
     playerGoals[i] = result; 
    } 

    int minimum = playerGoals.Min(); 
    int maximum = playerGoals.Max(); 
    double average = playerGoals.Average(); 

    Console.WriteLine("The top player is {0} with a score of {1}", maximum); 
    Console.WriteLine(""); 
    Console.WriteLine("The average goals scored is {0}", average); 
    Console.WriteLine(""); 
    Console.WriteLine("The lowest goal scored is {1}"); 

    Console.ReadLine(); 

Answer 1

這裏有一些方法，你可以採取：

1. 查找與最大的球員得分

   string maxPlayer = names[Array.IndexOf(playerGoals, maximum)]; 
   

2. 自己計算最大的循環（或者因爲你正在接受輸入或之後），以一種方式跟蹤玩家。

3. 創建一個PlayerStats類，以便您有一個數組（PlayerStats[]）而不是兩個，並使用MoreLINQ'sMaxBy。這將以我認爲最好的代碼結束，但可能比您準備好的更先進（知道如何手動執行操作是一項很好的技能，儘管您並不總是在真實世界中使用它） 。

   var best = playerStats.MaxBy(x => x.Goals); 
   Console.WriteLine("The top player is {0} with a score of {1}", 
           best.Name, best.Goals); 
   
   public class PlayerStats 
   { 
       public string Name { get; set; } 
       public int Goals { get; set; } 
   } 
   

Answer 2

class Player 
     { 
      public string Name { get; set; } 
      public int goals { get; set; } 
     } 
     static void Main(string[] args) 
     { 
      Console.WriteLine("Enter the amount of players"); 
      int amount = int.Parse(Console.ReadLine()); 
      List<Player> _players = new List<Player>(); 
      for (int i = 0; i < amount; i++) 
      { 
       Player objPlayer = new Player(); 
       Console.WriteLine("Enter a players name"); 
       objPlayer.Name = Console.ReadLine(); 
       Console.WriteLine("Enter how many goals they have score this season"); 
       objPlayer.goals = int.Parse(Console.ReadLine()); 
       _players.Add(objPlayer); 

      } 

      int maxgoals = _players.Max(t => t.goals); 
      var maxplayer = _players.FirstOrDefault(t => t.goals == maxgoals).Name; 

      int mingoals = _players.Min(t => t.goals); 
      var minplayer = _players.FirstOrDefault(t => t.goals == maxgoals).Name; 

      var average = _players.Sum(t=>t.goals)/amount; 

      Console.WriteLine("The top player is {0} with a score of {1}", maxplayer, maxgoals); 
      Console.WriteLine(""); 
      Console.WriteLine("The bottom player is {0} with a score of {1}", minplayer, mingoals); 
      Console.WriteLine(""); 
      Console.WriteLine("The average goals scored is {0}", average); 
      Console.ReadLine(); 
     }
