C# Visual Application Programming Learning Hub

A structured learning repository combining theory (Intro) and hands-on Console & Windows Forms examples.

📚 Theory (Intro)

Foundational markdown lessons (all inside Intro/).

• Overview & Evolution
• Visual Programming Concepts
• The .NET Framework / Platform
• Visual Studio IDE Essentials
• Control Statements
• Strings
• Arrays
• Methods
• Object-Oriented Programming
• Events & Delegates
• Exceptions
• Databases & CRUD Overview
• GUI & Windows Forms Fundamentals
• Menus, Reports & MDI
• LINQ Basics

💻 Console Application Samples

Scenario-based examples mapped to theory:

#	Folder	Topic	Quick Description
01	Console Applications/01_BasicIO	Basic IO & Variables	ReadLine, validation, interpolation
02	Console Applications/02_ControlFlow	Control Flow	Menu, loops, switch
03	Console Applications/03_Strings	Strings	Analysis utilities
04	Console Applications/04_Arrays	Arrays	Stats, sorting, 2D matrix
05	Console Applications/05_Methods	Methods	Overloads, Random, Math
06	Console Applications/06_OOP	OOP	Inheritance & polymorphism
07	Console Applications/07_Exceptions	Exceptions	Robust division tool
08	Console Applications/08_InMemoryCRUD	CRUD	List-based student manager

� Combined / Larger Console Examples

Example	Path	Concepts
Calculator	MoreExamples/Calculator.cs	IO, Methods, Control Flow
StudentScores	MoreExamples/StudentScores.cs	Collections, LINQ, File IO, CRUD

�🖼 Windows Forms (Coming Soon)

Planned examples to be added under Form Applications/:

• Basic Form + Events (Button / TextBox validation)
• Calculator GUI (mirrors console version)
• CRUD with DataGridView (in-memory then DB)
• MDI Parent with Menus
• Crystal Report placeholder / conceptual notes

🗂 Suggested Progress Path

1. Read Intro overview & syntax basics.
2. Run BasicIO and experiment with inputs.
3. Study control flow & expand calculator.
4. Dive into Strings and Arrays examples.
5. Learn Methods then refactor earlier code.
6. Explore OOP; model simple domain.
7. Add error handling (Exceptions sample).
8. Build CRUD; prepare for persistence / DB.
9. Transition to GUI (Forms) once fundamentals are solid.

🧪 How to Run Samples

For quick compile (no .csproj yet) ensure you have .NET SDK & Mono for execution without project files, or convert each folder into a project:

# Example (inside a sample folder)
dotnet new console -n SampleTemp
mv Program.cs SampleTemp/Program.cs
cd SampleTemp
 dotnet run

Or using csc + mono on macOS:

csc Program.cs && mono Program.exe

🤝 Contributing

• Keep theory in Intro/
• Keep console examples in Console Applications/
• Keep forms examples in Form Applications/
• Each new example: its own folder + README + Program.cs

✅ Roadmap

• Exceptions theory page
• Database basics markdown
• GUI / WinForms basics markdown
• Events & Delegates markdown
• Menus & MDI markdown
• LINQ basics markdown
• Combined examples folder
• Persist CRUD to file/JSON sample
• Database connectivity sample (ADO.NET + SQLite)
• WinForms basic form sample
• WinForms CRUD with DataGridView
• MDI + Menus + simple report export
• LINQ + EF Core sample (future)

Happy Learning!
