C# Dictionary

The C# Dictionary<TKey, TValue> class implements a hashtable to store values based on unique keys. These keys enable efficient search and removal of elements within the collection. This class is situated within the System.Collections.Generic namespace.

C# Dictionary__PRESERVE_4__ example

Let's examine a sample Dictionary<TKey, TValue> class which stores items via the Add function and traverses through elements using a for-each loop. In this scenario, the KeyValuePair class is employed to access both the key and the value of each element.

Example


using System;

using System.Collections.Generic;



public class DictionaryExample

{

    public static void Main(string[] args)

    {

        Dictionary<string, string> names = new Dictionary<string, string>();

        names.Add("1","Sonoo");

        names.Add("2","Peter");

        names.Add("3","James");

        names.Add("4","Ratan");

        names.Add("5","Irfan");



        foreach (KeyValuePair<string, string> kv in names)

        {

            Console.WriteLine(kv.Key+" "+kv.Value);

        }

    }

}

Output:
