C# Basics for Beginners: Learn Coding with C#

Install Visual Studio community edition, download the installer, choose the .NET desktop development workload, and create a console project named my first project with the .NET framework to learn C#.

Learn basic C# programming by creating your first console app. Build a main method inside a class and namespace, print and read with Console.WriteLine and Console.ReadLine, then run with Ctrl+F5.

learn how to declare variables in C# with int, double, string, and char, including quotes for strings and single quotes for chars, and when to use var versus explicit types.

Discover the boolean data type, representing true or false as a variable type. Note that this course won't use booleans, but understand it as a possible boolean value.

Practice declaring variables with the correct data types in this C# homework, replacing question marks with integer, double, or string types.

Learn to declare variables with the correct data types for the homework: integer, double, string, char, and boolean.

Create a simple calculator by prompting for two numbers, parsing them to integers, computing their sum (and optionally product), and displaying the result on the console.

Create a simple greeting program in C# by reading your first name and second name from the console with Console.ReadLine, storing them as strings, and printing a welcome message.

Learn if else and conditional statements in C# by building a console app. The program asks your age and decides if you may enter a bar.

Demonstrate a switch statement in C# that determines if a person can enter the bar based on age, using cases for 17, 18, 19 with break statements.

practice writing a C# console program that reads three numbers, sums them, and uses if-else to report whether the total is greater than, less than, or exactly 100.

Master the for loop in C# by printing numbers 1 to 10 and understanding initialization, condition, and increment. Starting from zero is common for indices, and loops can include logic.

master while loops in C# by printing numbers from zero to one hundred, compare with for loops, and explore do while loops and incrementing the counter.

Practice for loops in C# basics for beginners with three homework tasks: print numbers 1 to 1000 to the console, then even numbers, then odd numbers using the modulo operator.

Master for loops to print 1 to 1000 on the console, then use the modulus operator to display even and odd numbers from 1 to 1000.

Learn how to define and call methods in C#, including static void, the main method, arguments, parameters, return types, and examples like multiply and add.

Create a void method named divide that prints the result of dividing two numbers, then call this method from main with two values to complete the homework.

Declare a static void method named divide that takes two numbers and prints their division, then call it from main with examples like 10 and 5.

Explore the basics of arrays by creating integer and string arrays, initializing elements, and accessing values by index. Print results to the console to see how zero-based indexing works.

Practice building arrays with hands-on homework: create a 10-number array and print specific indices to the console. Then build a days-of-week array and print Monday, Friday, and Sunday by indices.

Create and manipulate classes in C# during this lecture, using public, private, and static modifiers to control data visibility. Instantiate objects, access fields, and call methods to understand class design.

Demonstrate inheritance in object oriented programming by showing how derived classes reuse a base class, with dog and cat inheriting from animal and printing name and age.

Learn how enums, a type of constants with names, organize days of the week and other values, show indexing from zero and how to assign custom values in code.

Learn how properties, getters, and setters control data access, including read-only get and write-enabled set; see examples with date time and a health property that clamps values 0–100.

Learn how interfaces simplify C# code by declaring properties and methods, implementing them in classes, and using a sale method to enable organized, reusable object oriented code.

Learn how try catch blocks handle exceptions in C# by wrapping code in a try block and catching errors, with a divide by zero example.

Set breakpoints, step through code with F11, and debug an index out of bounds error in a seven-element days array caused by a duplicate Friday.
