- For this course I'll be using a custom dataset for all my examples. The dataset consists of two lists. One of customers and another of distributors for a fictional company that sells eco-friendly products. Each customer in the customer list has the following properties. Last name, first name, the state they reside in, the total amount of money they have spent on purchases and a list of products they have purchased. The distributors in the distributors list each have the following properties. Name and state that they reside in.
The majority of the examples in this course will use these datasets. There will be a few videos where I'll make changes to these datasets to better demonstrate certain concepts. But I'll point that out when I do that. I've included exercise files for you to practice with and to use as reference. They're organized in numbered directories for each chapter of the course. And the individual files are named according to the topics of the related videos. In each video folder you'll find a start and end folder. I've included the end state of each program so you can look at my final product.
When following along the start folder is the place to be.
In LINQ with C# Essential Training, engineer Olivia Chiu introduces techniques for querying, updating, and transforming data with LINQ. She covers standard queries—such as finding overlaps in two datasets and creating hierarchies—as well as complex chained queries. She also shows how to group and join LINQ queries with lambda expressions, and use LINQ to query SQL databases and XML documents. Last but not least, Olivia provides tips for optimizing the performance of your queries.
