キーと値をC＃のOrderedDictionaryコレクションに追加します

OrderedDictionaryコレクションにキーと値を追加するためのコードは次のとおりです-

例

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      OrderedDictionary dict1 = new OrderedDictionary();
      dict1.Add("A", "Books");
      dict1.Add("B", "Electronics");
      dict1.Add("C", "Smart Wearables");
      dict1.Add("D", "Pet Supplies");
      dict1.Add("E", "Clothing");
      dict1.Add("F", "Footwear");
      Console.WriteLine("OrderedDictionary1 elements...");
      foreach(DictionaryEntry d in dict1) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      OrderedDictionary dict2 = new OrderedDictionary();
      dict2.Add("1", "One");
      dict2.Add("2", "Two");
      dict2.Add("3", "Three");
      dict2.Add("4", "Four");
      dict2.Add("5", "Five");
      dict2.Add("6", "Six");
      Console.WriteLine("\nOrderedDictionary2 elements...");
      foreach(DictionaryEntry d in dict2) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      Console.WriteLine("\nIs OrderedDictionary1 equal to OrderedDictionary2? = "+(dict1.Equals(dict2)));
   }
}

出力

これにより、次の出力が生成されます-

OrderedDictionary1 elements...
A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear
OrderedDictionary2 elements...
1 One
2 Two
3 Three
4 Four
5 Five
6 Six
Is OrderedDictionary1 equal to OrderedDictionary2? = False

例

別の例を見てみましょう-

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      OrderedDictionary dict = new OrderedDictionary();
      dict.Add("1", "One");
      dict.Add("2", "Two");
      dict.Add("3", "Three");
      dict.Add("4", "Four");
      dict.Add("5", "Five");
      dict.Add("6", "Six");
      dict.Add("7", "Seven");
      dict.Add("8", "Eight");
      ICollection col = dict.Values;
      String[] strVal = new String[dict.Count];
      col.CopyTo(strVal, 0);
      Console.WriteLine("Displaying the values...");
      for (int i = 0; i < dict.Count; i++) {
         Console.WriteLine(strVal[i]);
      }
      Console.WriteLine("Is OrderedDictionary read-only? = "+dict.IsReadOnly);
      Console.WriteLine("The OrderedDictionary has the key 15? = "+dict.Contains("15"));
      Console.WriteLine("The OrderedDictionary has the key 5? = "+dict.Contains("5"));
   }
}

出力

これにより、次の出力が生成されます-

Displaying the values...
One
Two
Three
Four
Five
Six
Seven
Eight
Is OrderedDictionary read-only? = False
The OrderedDictionary has the key 15? = False
The OrderedDictionary has the key 5? = True
