C# Conditional Branching
The course is part of this learning path
The ability for software to perform tasks or functions based on the state of variables or data is intrinsic to programming. In plain language, that means responding appropriately to input from the user or some data feed. C# Conditional Branching primarily focuses on If and Switch statements, the main mechanisms for executing or branching to different code depending on whether a condition is true or false. A simple example is allowing users to log in if their username and password match those stored in the software.
- Learn and understand If-statement syntax and how to use it in different scenarios
- Learn and understand the Switch statement and how to use it
- Learn about evaluating multiple Boolean conditions
- See how the dotnet new command has changed with the release of .NET 6.0 and C# 10
This course is intended for students that are relatively new to programming but not absolute beginners and want to know how to make their software responsive and adaptive. Students should know the basics of a C# programs structure and have experience running a program within their development environment. While for-loops and object-oriented concepts will be mentioned in the course, in-depth knowledge of these topics isn't essential.
- A working development environment like VS Code or Visual Studio
- Basic knowledge of a C# program's structure
- C# Loops Deep Dive
- Introduction to Object Orientation and C# Classes
Demo Source Code
Before we get into the if-statement demo, I want to talk briefly about .NET 6, C# version 10, and the new app templates. Here I'm creating a new console app specifying the .NET 6 framework. When I open Visual Studio Code and Program.cs there is just one line writing to the console. This new feature eliminates all the boilerplate code with keywords like program and the using and namespace statements. The latest C# compiler, version 10, infers the required dependencies and program structure from the type of application you create.
The rationale is that you, the developer, aren't hampered or distracted by code that adds nothing to your program. I am not a fan. In fact, I find it unsettling. There are a couple of options if you're a bit old-school like me and like the pomp and ceremony of keywords and structure. You can add the use-program-main switch to the dotnet new command. This adds the program class and main function with the namespace, but not enclosed in curly braces and no using statements. Alternately, you can create a .NET 5 application, and in VS Code, change the target framework in the project file. You'll also need to change the output directory in launch.json. Clearly, a stripped-down program.cs is the future, so I'll need to get used to it at some point.
