An Introduction to LINQ in Delphi Prism
Cary Jensen – Jensen Data Systems
Relevant to: Delphi
This presentation provides Delphi Prism developers with an overview of LINQ (Language Integrated Query), a declarative language for working with collections of objects in .NET. Topics discussed include LINQ to Objects, LINQ to DataSets, LINQ to XML, and lambda expressions.
This session takes you *very* deep in the rabbit hole that hides the LINQ internals in Delphi Prism. All the secrets and all the compiler magic behind LINQ is explained in detail, so that you will be able to use only parts of LINQ where they help you. Especially lambda expressions and the way you can use them with extension methods will make your coding-Fu far more powerful than now, and this goes even further down.

At the core of LiveBindings, first introduced in Delphi XE2, is an expression engine designed to evaluate string expressions dynamically at runtime. This presentation looks at some of the internals of LiveBindings, and shows how the expression engine can be used to implement powerful side effects.
