LINQ Basics

Learn to filter, sort, and process collections efficiently using LINQ query and method syntax in modern C#.

The need to filter, sort, and perform various operations with collections and data sources is common. To simplify these tasks, .NET includes Language Integrated Query (LINQ), which allows us to perform SQL-like queries against various data sources.

There are several varieties of LINQ, including:

  • LINQ to Objects: This is used to work with .NET collections.

  • LINQ to Entities: This is used to work with database tables through Entity Framework.

  • LINQ to SQL: This is used to work with Microsoft SQL Server.
