Sample chapter: Manipulating Data Using LINQ

  • Article

This chapter from Microsoft ADO.NET Entity Framework Step by Step begins by introducing you to LINQ to Entities.The chapter won’t provide an extensive reference, but you’ll have enough information to perform common tasks and a few advanced tasks.

After completing the chapter, you’ll be able to

  • Describe the basics of LINQ to Entities functionality.
  • Specify how LINQ statements are compiled.
  • List and use the essential LINQ to Entities functions.

In most cases, developers with a strong C# background, but without an equally strong database background, use Language Integrated Query (LINQ) to query the databases they create and manage using the Entity Framework. LINQ to Entities offers a number of benefits to developers, but the main benefit is simplicity. It’s possible to create relatively complex queries without knowing much about the underlying database from a DBMS perspective. Developers can also use syntax that’s familiar to make the query, rather than resorting to working with SQL. In addition, the compiler performs part of the work of interacting with the database for the developer, so that the developer can focus on the dataset and not on the language used to access it. In short, the developer gains a considerable efficiency advantage using LINQ to Entities.

This chapter begins by introducing you to LINQ to Entities. You need to know something about how LINQ to Entities works, and you also need to know the syntax so that you can make queries. The chapter won’t provide an extensive reference, but you’ll have enough information to perform common tasks and a few advanced tasks. The point is that you’ll have the information required to get started using LINQ to Entities to perform useful work. The material provided will help you understand the examples better.
