hello @Palak you can use this method string str; string search; Console.WriteLine(Enter Your String); str = Console.ReadLine(); Console.WriteLine(Enter Search string); search = Console.ReadLine(); if(str.Contains(search)) { Console.WriteLine(Strint {0} contain {1}strsearch); } else { Console.WriteLine(Strint {0} doesn't contain {1}strsearch); } Console.ReadKey();

try this using System; using System.Linq; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { string abc = test; var doesContainS = abc.ToLowerInvariant().Contains('s'); if (doesContainS == true) Console.WriteLine(its present); else Console.WriteLine(its not present); Console.ReadLine(); } } }

var doesContainS = abc.ToLowerInvariant().Contains('s'); And no to check if a boolean variable is true you don't need == true The comparison operator itself returns a boolean value. EDIT Since the Contains method is an extension method my solution appeared to be confusing to some. Here are two versions that doesn't require you to add using System.Linq; : var doesContainS = abc.ToLowerInvariant().IndexOf('s') != -1; // or: var doesContainS = abc.IndexOf(s StringComparison.CurrentCultureIgnoreCase) != -1; Note: form Stackoverflow
