In the March issue of MSDN Magazine's Data Points column I explore a variety of the Standard Query Operators and how they work with LINQ. Here is a summary of the article:
In this month's column I will perform practical queries and operations with LINQ, using both LINQ to Objects and LINQ to Entities. I'll query a single collection of entities and dive deeper into a hierarchical set of entities using their navigation properties. I'll also show how you can apply many of the standard query operators to arrays and collections. I will demonstrate how LINQ's standard query operators are enhanced using lambda expressions and how they can let you parse specific information from a sequence and perform complex logic over a sequence.
