C# Dictionary Get Value By Key

This article will show you how you can prepare a dictionary and perform search operation for value by using key name in c#.net.

Some of my previous articles are as follows: How to Extract Text From PDF File Using C#.Net, How to Read a Text File Line by Line in C# in Console Application, Retrieve All Files Present inside a Directory & Sub Directory Using C#.Net.

So for this article we will create a new console application and add the below code.

using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Text; using System.Threading.Tasks; namespace ConsoleApplication1 {     class Program     {         //c# dictionary get value by key         static void Main(string[] args)         {             Console.WriteLine("Search For: Pakistan\n");             Dictionary<string, int> dictionary = new Dictionary<string, int>();             dictionary.Add("India", 1);             dictionary.Add("Pakistan", 2);             dictionary.Add("Sri Lanka", 3);             dictionary.Add("America", 4);             if (dictionary.ContainsKey("Pakistan"))             {                 int value = dictionary["Pakistan"];                 Console.WriteLine("Pakistan value is : " + value);             }             Console.WriteLine("\n\n------End Search--------\n");             Console.ReadLine();         }     } }

In above code I have prepared the dictionary and then added some value. After that I have search the value by key name. Hear I have shown example for Pakistan.
