Remove the element with the specified key from a SortedList in C#

CsharpServer Side ProgrammingProgramming

To remove the element with the specified key from a SortedList, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      SortedList sortedList = new SortedList();
      sortedList.Add("A", "1");
      sortedList.Add("B", "2");
      sortedList.Add("C", "3");
      sortedList.Add("D", "4");
      sortedList.Add("E", "5");
      sortedList.Add("F", "6");
      sortedList.Add("G", "7");
      sortedList.Add("H", "8");
      sortedList.Add("I", "9");
      sortedList.Add("J", "10");
      Console.WriteLine("SortedList elements...");
      foreach(DictionaryEntry d in sortedList) {
         Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
      }
      Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
      sortedList.Remove("H");
      Console.WriteLine("\nEnumerator to iterate through the SortedList...");
      IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      Console.WriteLine("Count of SortedList key-value pairs (Updated) = "+sortedList.Count);
   }
}

Output

This will produce the following output −

SortedList elements...
Key = A, Value = 1
Key = B, Value = 2
Key = C, Value = 3
Key = D, Value = 4
Key = E, Value = 5
Key = F, Value = 6
Key = G, Value = 7
Key = H, Value = 8
Key = I, Value = 9
Key = J, Value = 10
Count of SortedList key-value pairs = 10

Enumerator to iterate through the SortedList...
Key = A, Value = 1
Key = B, Value = 2
Key = C, Value = 3
Key = D, Value = 4
Key = E, Value = 5
Key = F, Value = 6
Key = G, Value = 7
Key = I, Value = 9
Key = J, Value = 10
Count of SortedList key-value pairs (Updated) = 9

Example

Let us see another example −

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main(String[] args) {
      SortedList sortedList = new SortedList();
      sortedList.Add("One", "Mouse");
      sortedList.Add("Two", "Keyboard");
      sortedList.Add("Three", "Headphone");
      sortedList.Add("Four", "Speakers");
      sortedList.Add("Five", "RAM");
      Console.WriteLine("SortedList elements...");
      foreach(DictionaryEntry d in sortedList) {
         Console.WriteLine("Key = "+d.Key + ", Value = " + d.Value);
      }
      Console.WriteLine("Count of SortedList key-value pairs = "+sortedList.Count);
      sortedList.Remove("Three");
      Console.WriteLine("\nEnumerator to iterate through the SortedList...");
      IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = " + demoEnum.Value);
      Console.WriteLine("Count of SortedList key-value pairs (Updated) = "+sortedList.Count);
   }
}

Output

This will produce the following output −

SortedList elements...
Key = Five, Value = RAM
Key = Four, Value = Speakers
Key = One, Value = Mouse
Key = Three, Value = Headphone
Key = Two, Value = Keyboard
Count of SortedList key-value pairs = 5

Enumerator to iterate through the SortedList...
Key = Five, Value = RAM
Key = Four, Value = Speakers
Key = One, Value = Mouse
Key = Two, Value = Keyboard
Count of SortedList key-value pairs (Updated) = 4
