Removing the specified key entry from HybridDictionary in C#

To remove the specified key entry from HybridDcitionary, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      HybridDictionary dict1 = new HybridDictionary();
      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("HybridDictionary1 elements...");
      foreach(DictionaryEntry d in dict1) {
         Console.WriteLine(d.Key + " " + d.Value);
      }
      HybridDictionary dict2 = new HybridDictionary();
      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("
HybridDictionary2 key-value pairs...");      
      IDictionaryEnumerator demoEnum = dict2.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      dict2.Remove("3");
      Console.WriteLine("
HybridDictionary2 key-value pairs...UPDATED");
      demoEnum = dict2.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

Output

This will produce the following output −

HybridDictionary1 elements...
A Books
B Electronics
C Smart Wearables
D Pet Supplies
E Clothing
F Footwear

HybridDictionary2 key-value pairs...
Key = 1, Value = One
Key = 2, Value = Two
Key = 3, Value = Three
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six

HybridDictionary2 key-value pairs...UPDATED
Key = 1, Value = One
Key = 2, Value = Two
Key = 4, Value = Four
Key = 5, Value = Five
Key = 6, Value = Six

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
using System.Collections.Specialized;
public class Demo {
   public static void Main() {
      HybridDictionary dict = new HybridDictionary();
      dict.Add("1", "Marketing");
      dict.Add("2", "Purchase");
      dict.Add("3", "Sales");
      dict.Add("4", "IT");
      dict.Add("5", "Finance");
      dict.Add("6", "Operations");
      Console.WriteLine("HybridDictionary key-value pairs...");
      IDictionaryEnumerator demoEnum = dict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      dict.Remove("3");
      Console.WriteLine("
HybridDictionary key-value pairs...UPDATED");
      demoEnum = dict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      dict.Remove("4");
      Console.WriteLine("
HybridDictionary key-value pairs...UPDATED");
      demoEnum = dict.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
   }
}

Output

This will produce the following output −

HybridDictionary key-value pairs...
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 3, Value = Sales
Key = 4, Value = IT
Key = 5, Value = Finance
Key = 6, Value = Operations

HybridDictionary key-value pairs...UPDATED
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 4, Value = IT
Key = 5, Value = Finance
Key = 6, Value = Operations

HybridDictionary key-value pairs...UPDATED
Key = 1, Value = Marketing
Key = 2, Value = Purchase
Key = 5, Value = Finance
Key = 6, Value = Operations
