どのように各ユーザの入力に番号を付けることができますか？ C＃の

Question

ちょうどC＃のを学び始め、私の質問はどのように私は、ユーザー入力の記録を保持します。このような順に：どのようにすることができます私は、入力数がなく、セットアップするために見える傾けることができ、私のコードではscore 1:

score 1: 98 
score 2: 76 
score 3: 65 
score 4: 78 
score 5: 56 

私はこの目標に 私の入力を達成：

98 
76 
65 
78 
56

Answer 1

ありますデータを順番に保存することができます。私は個人的にこれにList<int>をお勧めしたいと思います。

あなたは、単にとしてそれに物事を追加することができます。

var list = new List<int>(); 
list.Add(37); 
list.Add(95); 

そして、あなたはイテレータ（foreach(var score in list){...}）でそれを読んだり、個々の数字アウト（var firstScore = list[0]）を取得することができます。ドキュメントには、List<T>でできることの詳細が記載されています。

Answer 2

C＃（MSDN Collections）で利用できるコレクションを探すことができます。

あなたの場合、実際に注文を気にする必要はありません。List<int>を使用できます。それ以外の場合は、ご注文をご希望の場合はStack<int>またはQueue<int>をご利用ください。あなたが学生の名前+のコレクションを維持したい場合は、あなたがDictionary<string,int>

Answer 3

がInputGrade方法でprivate static int counter = 0;
などの入力をカウントする一つの変数を宣言し使用することができますスコア、以下

Console.WriteLine("{0}\n{1}", 
       "Enter the integer grades in the range 0-100", 
       "Type <Ctrl> z and press Enter to terminate input:"); 
counter++; 
System.Console.Write("score " + counter + ":"); 
input = Console.ReadLine(); //read user input 

のようにしてwhile (input != null)を内側に置きますそう

IncrementLetterGradeCounter(grade); 
counter++; 
System.Console.Write("score " + counter + ":"); 
input = Console.ReadLine(); 

以下のように入れ、出力は のようになります3210
