# LINQ in .NET

LINQ is a set of [extensions](https://www.mindstick.com/articles/12362/is-ajax-cart-extensions-necessary-for-e-commerce-websites) to the .NET [Framework](https://www.mindstick.com/forum/34615/software-framework-vs-library) that encompass [language](https://www.mindstick.com/startup/28/preply-the-fast-growing-platform-transforming-language-learning)-[integrated](https://www.mindstick.com/forum/33532/handler-pagehandlerfactory-integrated-has-a-bad-module-managedpipelinehandler-in-its-module-list) query, set, and [transform](https://www.mindstick.com/interview/511/what-are-the-steps-to-transform-xml-into-html-using-xsl) operations. It extends C# and Visual Basic with native language syntax for [queries](https://answers.mindstick.com/qa/96624/explain-queries-in-ms-access) and provides class [libraries](https://answers.mindstick.com/qa/49244/which-company-is-ahead-in-classification-of-data-for-libraries-innovations) to take advantage of these capabilities.\

In LINQ we used same format as SQL but some [difference](https://www.mindstick.com/articles/157114/good-news-or-bad-news-and-the-difference-is) like positioning, style in Select, where etc. We use the System.Linq namespace.\

##### Benefits of LINQ:

- It provides rich Meta data.

- Compile-time syntax checking

- LINQ is [static typing](https://www.mindstick.com/forum/160151/typescript-s-approach-to-static-typing) and provide intelliSence (previously available in imperative code).

- It provides query in concise way.

We create LINQ between LINQ to object, LINQ to XML, [LINQ to SQL](https://www.mindstick.com/articles/338528/how-to-use-linq-to-sql-select-query-using-c-sharp).\
\
Example

```
using System.Collections.Generic;
using System.Linq;
string[] Country = { "India", "SriLanka", "China",  "Nepal", "Newzeland", "South Africa","America", "England" };
//In this section using LINQ Query
IEnumerable<string> query = from s in Country  where s.Length == 5  orderby s    select s.ToUpper();
foreach (string item in query)
Console.WriteLine(item);
```
