Course content

2 sections • 36 lectures • 8h 43m total length

  • Introduction to the course5:24
  • Quiz
  • Downloading and Installing the software3:31
  • LINQ Concepts: types of C# collections and LINQ functions43:30
  • OrderBy, OrderByDescending and Reverse functions7:19
  • MaxBy, MinBy, Max, Min and Average functions3:53

    Explore maxby, minby, max, min, and average in C# LINQ, including empty-list handling with the null-forgiving operator, computing oldest and youngest ages, totals, and double values for averages.

  • Where functions6:13
  • Select functions3:34
  • Aggregate, Enumerable.Range and DefaultIfEmpty functions12:49
  • Concat functions1:51

    Demonstrate merging two arrays with the concat function to form a single sequence, select names, and join them with a comma, while explaining that iteration triggers deferred execution.

  • Distinct functions1:34
  • SequenceEqual functions1:46
  • Prepend and Append functions2:10
  • ToList, ToArray and ToHashSet functions + HashSet explanation7:30

    Learn how to use ToList, ToArray and ToHashSet in LINQ, compare distinct versus unique values, and understand HashSet performance and equals logic.

  • First, FirstOrDefault, Single, SingleOrDefault, Last and LastOrDefault functions7:54
  • Any and All functions3:23
  • OfType and Cast functions3:43

    Filter a list by type using OfType, and use Cast to convert items to the right type, illustrated with super person and person examples and casting errors.

  • Zip function Part 12:57

    Explore how the zip function merges two lists, such as names and ages, to create a new person, showing mapping via a selector and understanding zero-based indexing.

  • Zip function part 20:41

    Zip combines elements from lists of different lengths by taking items up to the shortest list and ignoring the extra elements, as shown when Eric is excluded.

  • GroupBy and ToLookup functions6:57
  • ToDictionary function7:08

    Explore how to use the ToDictionary function to map car names to objects, compare dictionary lookups with single or default, and gain faster lookups via hashing.

  • Take, TakeLast, Skip and SkipLast functions2:50

    Learn how to paginate data with take, take last, skip, and skip last in linq, using a car list to fetch the first five, last five, and subsequent pages.

  • Select (with index) and ElementAt functions4:54
  • Enumerable.Repeat functioon0:35
  • SelectMany function4:45
  • Intersect, Union and Except functions4:02
  • Iterator functions25:10
  • Pratice Problem #1 - Concat Square Digits2:16
  • Practice Problem #2 - Factoring a number1:59

    Explore a naive factoring method that lists a number’s factors via mod tests and checks primality by counting factors, highlighting inefficiency for large inputs with LINQ.

  • More Practice Problems19:03

    Explore practical LINQ and C# problems by building tests, filtering and comparing sequences, and solving a temperature closest to zero challenge using aggregates and null handling.

Requirements

  • Having some basic notion of programming or maths can help, but the course starts from scratch
  • Downloading and installing the software to work (if you don't know how, don't worry, it's very easy, free, and I'll explain it to you in class 2!)
  • A decent computer and above all, a desire to learn!

Description

Become a LINQ and C# Programmer and learn one of employer's most requested skills nowadays!

This comprehensive course is designed for students, engineers, researchers... to be able to use LINQ and C# language from scratch to program in a simple and practical way. Never mind if you have no experience in programming, you will be equally capable of understanding everything and you will finish the course with mastery of the subject.

After several years working as an Engineer, I have realized that mastering LINQ to program today is something very necessary in engineering or other programming applications, like SQL. C# is one of the most used programming languages in the world, and its demand is increasing. Knowing how to program this language in LINQ can give you many job opportunities and many economic benefits, especially in the scientific or engineering field.

The big problem has always been the complexity to learn that programming requires, since its understanding is not easy. In this course I try to facilitate this entire learning and improvement process, and you will be able to carry out and understand your own codes in a short time, thanks to the step-by-step and detailed examples of every concept.

With over 30 lectures and almost 9 hours of video this comprehensive course leaves no stone unturned! This course includes coding exercises and theoretical explanations as well as practical examples to master LINQ and SQL. This course will teach you programming in a practical manner.

We will start by helping you get Visual Studio (interface) installed on your computer, regardless of your operating system, whether its Linux, MacOS, or Windows, we've got you covered.

Then, we will cover a wide variety of topics, including:

  • Installation and Introduction to LINQ and C#

  • Interface and basic tools of Visual Studio

  • C# language from scratch to advanced programming level

  • All LINQ functions

  • C# collections

  • ZIP functions

  • Iterator functions

  • LINQ to SQL

  • How to Set Up Entity Framework core

  • Simple Relational Mapping in Index CRUD page

  • Integrating an SQL to Linq query property

  • Setting up complex database structures

  • Setting up pagination and filtering

  • Practical Exercises

  • and much more!

In other words, what I want is to contribute my grain of sand and teach you all those things that I would have liked to know in my beginnings and that nobody told me. In this way, you will be able to learn to code different types of algorythms quickly and make versatile and complete use of LINQ and C# language. And if that were not enough, you will get lifetime access to almost 40 lectures and I will be at your disposal and I will answer all the questions you want in the shortest possible time.

Learning LINQ and C# Programming has never been easier. What are you waiting to join?

Who this course is for:

  • Beginners who have never programmed before
  • Programers switching languages to C#
  • Itermediate or advanced LINQ and C# programmers who want to level up their skills!
  • Any person who wants to start LINQ, C# or SQL in a practical and easy way
