Insert into OrderedDictionary with key and value at specified index in C#
To insert into OrderedDictionary with key and value at specified index, the code is as follows −
Example
using System; using System.Collections; using System.Collections.Specialized; public class Demo { public static void Main(){ OrderedDictionary dict = new OrderedDictionary(); dict.Add("A", "Books"); dict.Add("B", "Electronics"); dict.Add("C", "Smart Wearables"); dict.Add("D", "Pet Supplies"); Console.WriteLine("OrderedDictionary elements..."); foreach(DictionaryEntry d in dict){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("Count of elements in OrderedDictionary = " + dict.Count); dict.Insert(4, "E", "Clothing"); dict.Insert(5, "F", "Footwear"); Console.WriteLine("OrderedDictionary elements...UPDATED"); foreach(DictionaryEntry d in dict){ Console.WriteLine(d.Key + " " + d.Value); } Console.WriteLine("Count of elements in OrderedDictionary (UPDATED) = " + dict.Count); dict.Remove("E"); Console.WriteLine("Count of elements in OrderedDictionary (Updated)= " + dict.Count); } }
Output
This will produce the following output −
OrderedDictionary elements... A Books B Electronics C Smart Wearables D Pet Supplies Count of elements in OrderedDictionary = 4 OrderedDictionary elements...UPDATED A Books B Electronics C Smart Wearables D Pet Supplies E Clothing F Footwear Count of elements in OrderedDictionary (UPDATED) = 6 Count of elements in OrderedDictionary (Updated)= 5
Example
Let us now see another example −
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))); } }
Output
This will produce the following output −
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 OrderedDictionary2 elements...UPDATED 1 One 2 Two 3 Three 10 Ten 4 Four 5 Five 6 Six Is OrderedDictionary1 equal to OrderedDictionary2? = False
