Bây giờ chúng ta hãy xem một ví dụ khác -
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))); dict2.Insert(3, "10", "Ten"); Console.WriteLine("\nOrderedDictionary2 elements...UPDATED"); foreach(DictionaryEntry d in dict2){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("\nIs OrderedDictionary1 equal to OrderedDictionary2? = "+(dict1.Equals(dict2))); } }
