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("
OrderedDictionary2 elements...");
foreach(DictionaryEntry d in dict2){
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("
Is OrderedDictionary1 equal to OrderedDictionary2? = "(dict1.Equals(dict2)));
dict2.Insert(3, "10", "Ten");
Console.WriteLine("
OrderedDictionary2 elements...UPDATED");
foreach(DictionaryEntry d in dict2){
Console.WriteLine(d.Key + " " + d.Value);
}
Console.WriteLine("
Is 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
