LINQ to Objects

Video description

Your complete video course in writing queries with LINQ to Objects: hands-on skills for real-world success!



Tackling what can be a cumbersome topic, in an engaging way top .NET architect & developer and Microsoft Regional Director, Colin Melia helps you master real-world skills for success with LINQ to Objects. Drawing on 20+ years of experience developing solutions with Microsoft technologies, Colin demonstrates core techniques for building efficient LINQ to Objects queries against in-memory data structures, using core LINQ to Objects standard query operators, LINQ to XML, and extending LINQ to Objects to do even more. First, you discover what LINQ to Objects can do and when you might want to use it. Then, step by step, you walk through creating and executing queries in two different query styles against sets of objects using core technologies in the C#/VB compilers and classes in the .NET framework, mastering the most widely used Standard Query Operators, querying XML documents using .NET classes to represent parts of an in-memory document, doing the same things in VB with the differences from C# highlights, and extending LINQ with your own source providers and operators. Finally, you explore examples in a larger code base, parsing XML or JSON data from the Internet in an application. Everything's organized into bite-sized, self-contained sessions so that you can master key skills in as little as five minutes!
