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
