C＃のペアクラス

Pairクラスは、C＃を使用して値のペアを単一のリストに格納するKeyValuePairクラスです。

KeyValuePairを宣言する-

var myList = new List<KeyValuePair>string, int>>();
Now, add some elements:
myList.Add(new KeyValuePair<string, int>("Laptop", 1));
myList.Add(new KeyValuePair<string, int>("Desktop System", 2));
myList.Add(new KeyValuePair<string, int>("Tablet", 3));
myList.Add(new KeyValuePair<string, int>("Mobile", 4));
myList.Add(new KeyValuePair<string, int>("E-Book Reader", 5));
myList.Add(new KeyValuePair<string, int>("LED", 6));

以下に示すように、KeyValuePairを表示します-

例

using System;
using System.Collections.Generic;

class Program {
   static void Main() {
      var myList = new List<KeyValuePair<string, int>>();
      // adding elements
      myList.Add(new KeyValuePair <string, int>("Laptop", 1));
      myList.Add(new KeyValuePair <string, int>("Desktop System", 2));
      myList.Add(new KeyValuePair <string, int>("Tablet", 3));
      myList.Add(new KeyValuePair <string, int>("Mobile", 4));
      myList.Add(new KeyValuePair <string, int>("E-Book Reader", 5));
      myList.Add(new KeyValuePair <string, int>("LED", 6));

      foreach (var val in myList) {
         Console.WriteLine(val);
      }
   }
}
