In this video Pat Tormey demonstrates ‘How To’ use LINQ with the file system. With a LINQ Query Pat extracts, filters, and sorts the file objects while importing the list into a list based on a custom class in only a couple of lines of code. Author: Pat...
In this video learn the main features of LINQ to DataSet which provides LINQ (Language Integrated Query) capabilities for DataSet objects. First, learn the fundamentals of querying a DataSet then see how to do more complicated filtering and ordering....
In this video you will learn about the new LINQ enabled XML API in Visual Studio 2008. First learn how to load XML from disk or create XML in code with XML literals in VB or XElement in C#. Once XML is loaded see how powerful LINQ queries can be executed...
In this video Chris Pels demonstrates how to add, modify, and delete data in a database using LINQ to SQL entity mapping classes. The entity mapping classes are created using the sqlmetal.exe command line utility which is the “engine” behind the Object...
In this video Chris Pels demonstrates how to create LINQ to SQL associations to represent foreign key relationships in the database. This video is code oriented rather than using the Object Relational Designer to demonstrate the fundamental principles...
In this video Chris Pels demonstrates a beginning-to-end LINQ to SQL scenario by creating a simple object model in LINQ to SQL using the entity mapping classes. Next, a LINQ query is written to list the customers in London for that object model. This...
In this video Chris Pels will demonstrate how to create entity classes representing SQL Server tables using the new object/relational designer (O/R Designer) in Visual Studio 2008. The entity classes will then be bound to a GridView on a web page using...
In this video Chris Pels demonstrates a beginning-to-end LINQ to SQL scenario for accessing data using the entity mapping classes and methods that are intermediaries to stored procedures in the database. The entity mapping classes are created using the...
In this video interview, Anders Hejlsberg, the chief architect of C#, describes features in the next release of C#, code named Orcas. Anders first describes how LINQ solves the impedance mismatch between the code that lives on a database server and the...
Visual Basic programmers will learn how to write simple LINQ queries over objects by navigating files on the file system.
