Search in a SortedList object in C#

To search in a SortedList object, the code is as follows −

Example

 Live Demo

using System;
using System.Collections;
public class Demo {
   public static void Main() {
      SortedList list = new SortedList();
      list.Add("1", "One");
      list.Add("2", "Two");
      list.Add("3", "Three");
      list.Add("4", "Four");
      list.Add("5", "Five");
      list.Add("6", "Six");
      list.Add("7", "Seven");
      list.Add("8", "Eight");
      Console.WriteLine("Key and Value of SortedList....");
      foreach(DictionaryEntry k in list )
      Console.WriteLine("Key: {0}, Value: {1}", k.Key , k.Value );
      Console.WriteLine("Is the SortedList having the value? "+list.ContainsValue("Three"));
      Console.WriteLine("The SortedList object has a fixed size? = "+list.IsFixedSize);
      Console.WriteLine("Does the SortedList object contains key 10? = "+list.ContainsKey("10"));
   }
}

Output

This will produce the following output −

Key and Value of SortedList....
Key: 1, Value: One
Key: 2, Value: Two
Key: 3, Value: Three
Key: 4, Value: Four
Key: 5, Value: Five
Key: 6, Value: Six
Key: 7, Value: Seven
Key: 8, Value: Eight
Is the SortedList having the value? True
The SortedList object has a fixed size? = False
Does the SortedList object contains key 10? = False

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("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);
      Console.WriteLine("
Enumerator to iterate through the SortedList...");
      IDictionaryEnumerator demoEnum = sortedList.GetEnumerator();
      while (demoEnum.MoveNext())
      Console.WriteLine("Key = " + demoEnum.Key + ", Value = "+ demoEnum.Value);
      Console.WriteLine("Does the SortedList object contains key M? = "+sortedList.ContainsKey("M"));
      Console.WriteLine("Does the SortedList object contains key H? = "+sortedList.ContainsKey("H"));
   }
}

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 = H, Value = 8
Key = I, Value = 9
Key = J, Value = 10
Does the SortedList object contains key M? = False
Does the SortedList object contains key H? = True
