C# Lessons for Beginners

The object-oriented programming language C# was formed by Microsoft to create applications. Among the main advantages are simplicity and speed of software development of any level of complexity. Suitable for starting a career in high-tech.

Introduction

You will need a development environment in which to write and execute code. On the example of work with MonoDevelop you will understand the sequence of project creation. When creating a new one the structure – the initial shell appears. This is also where the Sistem library is plugged in, which allows you to use all the basic functions and parameters of the program. All subsequent commands are placed in the main Main function.

C# mini course

This video course is designed for beginner developers who want to learn the powerful and promising C# programming language. From the lesson you will learn about setting up a special environment for development, about variables as important elements of any language and syntax, data types. Arithmetic operations, conditional statements, arrays, loops, and much more useful theory are studied.

The first program in Visual Studio

The video tutorial shows you how to install and set up a development program and how to run your first project. There is a link below the video where you can download it. After installing it on your computer, you need to create a project. You need to select C# to install the application console. The external shell of the program appears, which is already working. All further actions will take place inside. You can run it through the tab “Debugging”.

Creating the application

The video consists of three parts and is dedicated to learning C# .NET Windows Forms or WinForms. A small application with registration and authorization will be created in Visual Studio, in which all actions will be synchronized with MySQL. We learn how to work with the graphical interface and add information handlers, connect databases and implement them within the project. For the development of a beautiful interface, there are special frameworks. In this case, the basic Studio tools that can be used to create elements.

Books for the programmer

Here is an overview of books that will help you pump your knowledge and become an advanced developer. Here are the best picks to study, covering the basic knowledge any beginner needs, as well as the advanced level, for those who want to improve in the direction of application development. In addition, it tells about the literature that is not worth studying and wasting your time at all. The video presents books on syntax for beginners, project development on the Microsoft .NET FRAMEWORK platform, codes and many others.

Variables

The lesson deals in detail with the concept of variable, constant and data types. Arithmetic operators, comparison operators are considered. Their use on examples is studied, after which you can correctly determine which type should be used in a particular situation. Attention is also paid to arithmetic operations on the values of variables and their comparison. Information on string formatting is given at the end.

Classes and objects

The video introduces the concept of object-oriented programming (OOP) and what it is based on. The important components, such as classes and objects, are also revealed. A class is a syntactic construction which consists of: keyword, name, body which in its turn contains other constructions. Next, the components of the classes themselves (those elements that can be included in them) are discussed. We discuss constructions, which are not typical for most OOP, but are present in C# – properties.

Syntax

At the beginning of the code, there are lines that begin with the word using, denoting permission to connect certain system libraries. The console type is stored in the System space, which must be prescribed to be usable. The program lets you connect it automatically. The words using, namespace, static, void are keywords, reserved identifiers. The language uses curly braces, inside which is a block of code that describes the types (class, struct, enum).

Directives, classes, methods

The video describes the elements of the language in more detail, exploring in greater depth the code and libraries that are connected through separate strings. The work will be done through Visual, so you must first download it and create a new project. Then the necessary controls (buttons) should be added. By double-clicking on them, they appear in the event handler. This speeds up the transition between the constructor and the handler. If errors appear in the code, the program will indicate them to the developer.
