Webudvikling Med C#

In this section we will get an introduction to C#. Moreover, we will also learn some basic elements of the C# language.

In any programming language we have to deal with different types of data. In this section we will learn about that.

In this section we will learn about features of C# that help us control the flow of the program such as executing pieces of code based on conditions.

In this section we will learn about how to deal with repetitive tasks in programming.

Arrays are an important part of any programming language as they let us group together and manipulate a large amount of similar data. In this section we will learn about Arrays and how to use them for practical applications.

In this section we will learn about one of of the most widely used and essential features of C# called Methods. We will also explore its uses through creative practice tasks.

In this section we will learn data structures like Lists and Dictionaries. We will also learn how to read and write files. In the end we will look at how to deal with unexpected errors which can occur during the program's execution.

In this section we will learn about some more advanced structures for storing data, namely Structs and Enumerators. We will learn how to use them and we will look at some practice examples as well.

In this section, we will learn what Object-Oriented Programming (OOP) is and how we can create programs that use the concept of OOP. We will also practice this concept with many hands-on tasks that are fun to solve.

In this section, we delve deeper into the essentials of Object-Oriented Programming (OOP). We explore advanced topics to enhance your understanding and proficiency in OOP. From managing object lifecycles through destructors to refining class structures with access modifiers, and harnessing the power of derived classes and method overloading, this section equips you with the knowledge and practical skills needed to design robust and flexible object-oriented systems.

This will be a detailed chapter in which we will dive deep into the main principles of Object-Oriented Programming (OOP). We will also look at many practical applications and hands-on examples of these principles to understand them better. In this section we will revise some of the concepts from the previous section in a bit more detail and combine the concepts together to understand it more thoroughly.

I dette afsnit lærer vi at bruge SQL SELECT-sætningen til at hente en enkelt tabelkolonne, flere tabelkolonner og alle tabelkolonner. Vi finder også ud af, hvordan man returnerer unikke værdier.

I dette afsnit undersøger vi, hvordan man organiserer og prioriterer de data, der returneres af en forespørgsel ved hjælp af ORDER BY-klausulen. Placeret i slutningen af en SELECT-sætning giver denne klausul mulighed for at sortere resultaterne efter én eller flere kolonner, enten i stigende eller faldende rækkefølge, hvilket muliggør en mere meningsfuld og letfortolkelig dataoutput.

I dette afsnit lærer vi, hvordan man filtrerer returnerede data ved hjælp af SELECT-sætningens WHERE-klausul. Vi lærer, hvordan man tester for lighed, ulighed, større end og mindre end værdier samt NULL-værdier.

I dette afsnit undersøger vi, hvordan du kan forfine dine søgebetingelser ved at kombinere WHERE-klausuler med AND- og OR-operatorerne. Vi gennemgår også, hvordan NOT-operatoren kan bruges til at udelukke bestemte resultater.

I dette afsnit vil vi lære, hvad SQL-aggregatfunktioner er, og hvordan de bruges til at opsummere tabeldata.

I denne sektion vil du lære, hvordan du grupperer og administrerer data effektivt. Vi vil introducere GROUP BY-operatøren til gruppering af data. Derudover vil du lære, hvordan du filtrerer grupperede data ved hjælp af HAVING-operatøren.

Du vil lære om indlejrede subqueries, hvordan man opretter dem, og hvordan man bruger dem effektivt.

Her vil du lære, hvordan man kombinerer flere tabeller, så du kan arbejde med en samlet tabel og forenkle oprettelsen af forespørgsler.

Lær grundlæggende om Data Definition Language (DDL) og Data Manipulation Language (DML) i SQL, herunder hvordan man opretter, ændrer og sletter databaseobjekter, samt hvordan man indsætter, opdaterer og sletter data i tabeller.

I dette afsnit vil vi lære om, hvad .NET er, hvordan man opsætter udviklingsmiljøet, og hvordan man begynder at lave nogle konsolapplikationer. Derudover vil vi også lære, hvordan man modtager input fra brugeren i konsollen for at skabe interaktive applikationer.

I dette afsnit lærer vi, hvordan man udfører flere opgaver samtidigt for at forbedre applikationers ydeevne og reaktionshastighed. Vi gennemgår også kort, hvad webtjenester og API'er er. Dette giver en introduktion til, hvordan internettet og websites fungerer. Vi lærer desuden, hvordan man anvender API'er.

I dette afsnit gennemgår vi, hvad databaser er, specifikt hvad SQL-databaser er, og hvordan de oprettes. Vi undersøger deres struktur og lærer at udføre nogle grundlæggende operationer på databaserne. Dette kapitel fungerer som en introduktion til ADO.NET, som er et .NET-modul til interaktion med databaser.

I dette afsnit gennemgår vi de grundlæggende CRUD-operationer (Create, Read, Update, Delete) ved hjælp af SQL. Vi udforsker SQL-syntaks på et basalt niveau og opsummerer, hvordan hver SQL-sætning implementeres i C#-kode. Selvom nogle dele kan fungere som en repetition fra det forrige afsnit, vil dette give en solid forståelse af essentielle databasekoncepter, så du kan forstå både SQL- og C#-kode og skrive det selvstændigt.

I dette kapitel gennemgår vi yderligere funktioner eller metoder til at gøre databaseadministration mere effektiv. For eksempel udførelse af flere SQL-kommandoer på én gang ved hjælp af lagrede procedurer samt hentning af data i bulk fra SQL-databasen ved hjælp af DataSet.

Get an introduction to the web and HTML, including the significance of tags, elements, and attributes. Learn about the basic structure of an HTML document and the brief history of the web.

Master the essentials of HTML markup, focusing on special text formatting and lists, understanding their significance in structuring content within an HTML document. Dive into the intricacies of HTML document structure while refining text markup techniques.

Unlock the power of visual and auditory content in web development as you learn to seamlessly integrate images, video, and audio elements into HTML documents. Explore the nuances of incorporating various media formats.

Navigate the intricacies of data presentation and user interaction with comprehensive coverage of tables and forms in HTML, encompassing table structures, form creation, and input elements. Gain proficiency in implementing form input elements and leveraging attributes for enhanced functionality.

Elevate your HTML skills to the next level by delving into semantic HTML elements, empowering you to create well-structured and accessible web content. Embark on building your first website, applying newfound knowledge to bring your ideas to life.

In this section, we will learn what MAUI is, and how to set up a .NET MAUI application. We will also look at the structure of an MAUI application, and in the end, we will learn how to add some basic elements to our UI. This section will prepare us for the rest of the course where we will be working with more practical concepts.

In this section we will learn about delegates, events and data binding. Using this knowledge we will learn how to make interesting interactive GUI applications.

In this section, we will learn what Threading is and how to use it to keep our applications responsive, and run smoothly while performing resource intensive tasks. We will see how to differs from other similar concepts on C# and what are good practices when implementing Threading in our application. There will also be some interesting tasks to help us in understand this concept on a deeper level.

In this section, we will learn how to make more robust methods, classes and other objects which can work multiple types of input data types, by first learning about Generics and how to implement generic classes, then we will move on to Reflection and how to use reflection for further improving the capabilities of our programs.
