Get or Set the value associated with specified key in Hashtable in C#



To get or set the value associated with specified key in Hashtable, the code is as follows −

Example

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main() {       Hashtable hash = new Hashtable();       hash.Add("1", "AB");       hash.Add("2", "BC");       hash.Add("3", "DE");       hash.Add("4", "EF");       hash.Add("5", "GH");       hash.Add("6", "IJ");       hash.Add("7", "KL");       hash.Add("8", "MN");       hash.Add("9", "OP");       hash.Add("10", "QR");       Console.WriteLine("Value at key 3 = "+hash["3"]);    } }

Output

This will produce the following output −

Value at key 3 = DE

Example

Let us see another example −

 Live Demo

using System; using System.Collections; public class Demo {    public static void Main() {       Hashtable hash = new Hashtable();       hash.Add("1", "AB");       hash.Add("2", "BC");       hash.Add("3", "DE");       hash.Add("4", "EF");       hash.Add("5", "GH");       hash.Add("6", "IJ");       hash.Add("7", "KL");       hash.Add("8", "MN");       hash.Add("9", "OP");       hash.Add("10", "QR");       Console.WriteLine("Value at key 3 = "+hash["3"]);       hash["3"] = "UV";       Console.WriteLine("Value at key 3 (UPDATED) = "+hash["3"]);    } }

Output

This will produce the following output −

Value at key 3 = DE Value at key 3 (UPDATED) = UV
