Chapter 5: LINQ to ADO.NET


Overview

Language Integrated Query (LINQ) is available in several “flavors.” The intrinsic extensibility of LINQ makes it useful in many situations where data manipulation is required. At the time of this writing, Microsoft has announced LINQ to SQL, LINQ to DataSet, LINQ to Entities, and LINQ to XML implementations. Other LINQ integrations will soon be available from both Microsoft and third parties.

LINQ to ADO.NET includes several LINQ implementations that operate with Microsoft ADO.NET:

  • LINQ to SQL allows querying a relational structure by converting the LINQ query into a native SQL query.

  • LINQ to DataSet interacts with data already in ADO.NET DataSet structures.

  • LINQ to Entities leverages the ADO.NET Entity Framework to query a logical model that usually has a higher-level representation of data information compared to direct access to relational data sources.
