What is LINQ and INTRODUCTION of LINQ

·      Full Form Of LINQ Language Integrated Query

·      Query expressions can be used to query and to transform data from any LINQ-enabled data source. For example, a single query can retrieve data from a SQL database, and produce an XML stream as output.

 

·      A query is not executed until you iterate over the query variable, for example, in a foreach statement.

 

·      XML documents: LINQ to XML

 

·      ADO.NET Entity Framework: LINQ to entities

Example

int[] numbers = { 20, 32, 45, 60, 90, 10, 5 };

            var result = from s in numbers

                         where s > 20

                         select s;

            foreach (var item in result)

            {

                Response.Write(item + "</br>");

            }

            return View();
