Remove the entry at specified index from OrderedDictionary in C#

To remove the entry at specified index from OrdererdDictionary, the code is as follows −

Example

 Live Demo

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");       dict.Add("E", "Clothing");       dict.Add("F", "Footwear");       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.RemoveAt(4);       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 E Clothing F Footwear Count of elements in OrderedDictionary = 6 Count of elements in OrderedDictionary (Updated)= 5

Example

Let us see another example −

 Live Demo

using System; using System.Collections; using System.Collections.Specialized; public class Demo {    public static void Main() {       OrderedDictionary dict = new OrderedDictionary();       dict.Add("1", "AB");       dict.Add("2", "CD");       dict.Add("3", "MN");       dict.Add("4", "PQ");       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.RemoveAt(1);       dict.RemoveAt(2);       Console.WriteLine("Count of elements in OrderedDictionary (Updated)= " + dict.Count);    } }

Output

This will produce the following output −

OrderedDictionary elements... 1 AB 2 CD 3 MN 4 PQ Count of elements in OrderedDictionary = 4 Count of elements in OrderedDictionary (Updated)= 2
