Linq in C Sharp

With LINQ, you can query data from sql, object collections, xml, json or any other format

Example

In below example, we are using Linq syntax to fire a query on String array. Similarly we can use linq to query different types of data as well. For example - let say we have a list of car objects and we want to sort those objects based on price. Then we can use below syntax

var orderByPrice = from car in carList
                   orderby car.price
                   select car;

using System.Linq;
using System;
namespace mstest
{
    [TestClass]
    public class UnitTest1 : Base
    {
        [TestMethod]
        public void TestMethod1()
        {
            string[] cities = { "brisbane","perth", "sydney" };
            var citylist = from city in cities
                              where city.Contains('y')
                              select city;

            foreach (var city in citylist)
                Console.WriteLine(city);
        }
    }
}
