LINQ is an abbreviation that stands for Language Integrated Query. Microsoft's query language is entirely integrated, allowing users to easily access data from in-memory objects, databases, XML documents, and other sources. LINQ successfully integrates queries in C# and Visual Basic using a series of extensions.

This LINQ tutorial will guide you through the LINQ language, covering fundamentals and sophisticated subjects. These tutorials are divided into a sequence of related subjects, so you can begin with a topic that needs to be understood first and then learn other LINQ capabilities in order.

The LINQ tutorials are jam-packed with simple explanations, real-world examples, helpful hints, informative notes, and key takeaways. These lessons are intended for both novices and experienced programmers who would like to learn LINQ in a step-by-step manner.

LINQ introduces a new approach to process data, whether from or to a database, an XML file, or a simple list of dynamic data. LINQ is a C# query framework that allows you to access data from various sources and formats. It is connected with C# to eliminate computer language and database mismatches. It provides a single query interface for several data sources.

SQL, for example, is a structured query language for saving and retrieving data from databases. C# is used to create LINQ. LINQ is a Structured Query Syntax in the same way. It can retrieve data from various sources, including XML, documents, collections, ADO.Net Dataset, Web Service, MS SQL Server, and other database servers.
