Complete Practical LINQ Tutorial in C#

Unlock the Power of LINQ and Functional Programming in C#

Are you ready to elevate your C# development skills? This course dives deep into LINQ (Language Integrated Query), a cornerstone of the .NET platform since C# 3, and explores the fundamental principles of functional programming. Learn to build robust and efficient applications by leveraging this incredibly powerful feature.

Many codebases still rely on older, procedural approaches. If you're struggling with LINQ or want to master its capabilities, this course is designed for you. LINQ, inspired by functional paradigms like F#, allows you to query data in a declarative and elegant way.

Here's a comprehensive look at what you'll learn:

• LINQ Fundamentals:

  • Extension Methods: Understand how extension methods enhance C# and enable powerful functionality.
  • Pipelining: Master the art of LINQ pipelining for concise and readable data manipulation.
  • IEnumerable: Explore the IEnumerable interface and its role in LINQ.
  • Custom Extension Methods: Learn to implement your own extension methods to tailor LINQ to your specific needs.
  • Query Syntax: Become proficient in both LINQ query syntax and method syntax.
  • LINQ Pitfalls: Avoid common LINQ operation pitfalls and write reliable code.
  • List Manipulation: Discover effective techniques for altering a list using LINQ.

• Generating Data Streams:

  • Enumerable Class: Understand the Enumerable class and its core operations.
  • Data Stream Implementation: Learn to implement your own extension to generate data streams.

• Filtering, Ordering, and Projecting:

  • CSV Parsing: Learn to parse a CSV file efficiently with LINQ.
  • Sorting: Utilize ThenBy, First, Last, Single, TakeWhile, SkipWhile, Any, All, Contains, and SequenceEqual for advanced data manipulation.
  • Projection: Master Select and SelectMany to transform and reshape your data.

• Joining, Grouping, and Aggregating:

  • Join Operations: Understand various Join types (Join, Group, GroupJoin, Zip).
  • Aggregation: Learn to calculate Sum, Average, Min, and Max values.

• Data Conversions:

  • Type Conversion: Utilize OfType, Cast, ToArray, ToList, ToDictionary, ToLookup, AsEnumerable, and AsQueryable for seamless data conversions.

• LINQ to XML:

  • XML Manipulation: Gain an overview of LINQ to XML.
