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
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 −
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
