Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster.

Understanding iteration statements

Iteration statements repeat a block of statements either while a condition is true (while and for statements) or for each item in a collection (foreach statement). The choice of which statement to use is based on a combination of ease of understanding to solve the logic problem and personal preference.

Looping with the while statement

The while statement evaluates a Boolean expression and continues to loop while it is true. Let’s explore iteration statements:

  1. Use your preferred coding tool to add a new Console App / console project named IterationStatements to the Chapter03 solution.
  2. In Program.cs, delete the existing statements and then add statements to define a while statement that loops while an integer variable has a value less than 10, as shown in the following code:
    int x = 0;
    while (x < 10)
    {
      WriteLine(x);
      x++;
    }
    
  3. Run the code and view the results, which should be the numbers 0 to...
