LINQ to search item from LIST in C#

Guys, are you familiar with LINQ? . If not I will suggest you to study some good tutorial of LINQ. What exactly it does. And if you are already done some work on LINQ and randomly clicking various article to know some extra knowledge .NET or basically programming languages then this post is suitable for you. Talking too much??

Ok, let’s come to point. Here I will show how to search particular item from a collection. Here I have created a collection of object of my person class. For sake of simplicity I have kept only two object of my class.

And in List collection I have created two object of my Person class. Now using LINQ I want to find some item from my collection. Here the query

var hasName = (from NameList in list

                           where NameList.Name == "Sourav"

                           select NameList).Any();

   

will find whether “Sourav” is present is not in name property in collection of object. If present then it will return true. Let’s see below code.

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Collections;

using System.Data;

using System.Diagnostics;

using System.Data.SqlClient;

using System.Collections.Generic;

namespace BlogProject

{

    class Person

    {

        public string Name { get; set; }

        public string Surname { get; set; }

    }

    class Program

    {

        static void Main(string[] args)

        {

            IList<Person> list = new List<Person>();

            Person p = new Person();

            p.Name = "Sourav";

            p.Surname = "Kayal";

            list.Add(p);

            p = new Person();

            p.Name = "Prasanta";

            p.Surname = "Kayal";

            list.Add(p);

            //Search in list to check wheather sourav is present or not

            var hasName = (from NameList in list

                           where NameList.Name == "Sourav"

                           select NameList).Any();

            if (hasName)

            {

                Console.Write("Name is present in list");

            }

            else

                Console.Write("Name not present");

            Console.ReadLine();          

        }

    }

}
