使用c＃从数组的每一行计算

Question

我对c＃和编程很新。我有一些问题试图让这个程序工作。

我要从文本文件中输入5个名称，为每个名称添加5个分数，删除每个名称的最大和最小分数，然后显示获胜者。到目前为止我所做的只是将所有分数加起来。有人能指出我正确的方向吗？

        int[] Finalscore = new int[5];
        int max1 = 0;

            {
                DiverScore = divers[i];

                Console.WriteLine("Please Enter a Score between 0 and 10 for {0}", DiverScore);
                score = Convert.ToInt16(Console.ReadLine());

从代码中可以清楚地看出你的目标是什么。至少，代码与您提供的任务描述不同。无论如何，我建议这样一个疯狂的猜测，例如：

更新 - 我根据您提供的工作代码修复了符合您需求的代码。

using System.IO;
using System.Linq;

namespace Diving_Championship
{

  class Program
  {
    private class Diver
    {
        internal Diver(string name)
        {
            Name = name;
        }

        internal readonly string Name;
        internal readonly int[] Scores = new int[5];

        internal int TotalScore
        {
            get { return Scores.OrderBy(sc => sc).Skip(1).Take(3).Sum(); }
        }
    }


    static void Main(string[] args)
    {

        string[] diverNames = File.ReadAllLines(@"F:\1 -C# Programming\Coursework\DiverName.txt");
        List<Diver> divers = new List<Diver>();

        for (int j = 0; j < 5; j++)
        {
            var diver = new Diver(diverNames[j]);
            for (int i = 0; i < 5; i++)
            {
                int score;
                do
                {
                    Console.WriteLine("Please Enter a Score between 0 and 10 for {0}", diver.Name);
                    score = Convert.ToInt32(Console.ReadLine());
                } while (score < 0 || score > 10);

                diver.Scores[i] = score;
                divers.Add(diver);
            }
        }

        var MaxScore = divers.Max(d => d.TotalScore);
        var Winner = divers.First(d => d.TotalScore == MaxScore);
        Console.WriteLine("The winner is {0} with score {1}", Winner.Name, MaxScore);        }
    }
  }
}

Answer 2

public class Person{
    private List<int> score;
    public string name;
    public Person(string name, int [] values)
    { 
         this.score = new List<int>(values); 
         this.score.Sort();
         this.score.RemoveAt(0);
         this.score.RemoveAt(this.score.Count - 1);
         this.name = name;
    }
    public int GetHigh(){ return this.score[score.Count - 1]; }
    public int GetLow(){ return this.score[0]; }
    public IEnumerable<int> GetValues(){ return this.score as IEnumerable<int>; }
}

int main(){
    Person jeff = new Person("Jeff", new int[]{6,7,5,4,1 });
    int hiScore = jeff.GetHigh();
    int lowScore = jeff.GetLow();
    foreach(int i in jeff.GetValues()) { print(i);}
}

Person类包含ctor中传递的名称和值列表。然后列表被排序。由于它按顺序排序，第一个是最低的，最后一个是最高的。你删除了那些，你留下了一个值列表。

Answer 4

感谢您已经解决了您的问题，但我想发布这个简短的示例解决方案：

Console.WriteLine("The max score is " + 
    File.ReadAllLines(@"F:\1 -C# Programming\Coursework\DiverName.txt")
    .Select(driver =>
    {
        int score;
        do Console.WriteLine("Please Enter a Score between 0 and 10 for " + driver);
        while (!int.TryParse(Console.ReadLine(), out score) || score < 0 || score > 10);
        return score;
    }).Max());
