Language Integrated Query (LINQ) Course Overview

Language Integrated Query (LINQ) Course Overview

The Language Integrated Query (LINQ) course is designed to teach learners the comprehensive aspects of querying data using LINQ in C#. It encompasses a variety of skills, from basic query expressions to advanced grouping and joining operations. The course starts with foundational concepts of what queries are and how they function, including the use of explicit and implicit typing. As learners progress, they will delve into mixed query and method syntax, querying collections, and effectively handling query results.

Advanced modules cover group query results, subqueries, grouped joins, and custom join operations, equipping students with the capability to handle complex data structures and relationships. Furthermore, the course addresses practical scenarios such as merging CSV files and handling null values to ensure robust query expressions. By completing this LINQ course, students will gain the LINQ training necessary to write efficient and maintainable queries, a valuable skill set for any developer working with data in .NET environments.
