.NET Development Fundamentals: Exception Handling, Debugging, and Testing Part 5

In Part 5 of your .NET development journey, you’ll dive into fundamental aspects of software development that ensure your applications are robust, reliable, and maintainable. Exception handling, debugging, and testing are essential skills for any developer. In this part, we’ll explore how to handle errors, debug code effectively, and perform unit testing, which are critical for building high-quality .NET applications.

Exception Handling in .NET

Exception handling is a crucial aspect of writing reliable software. In .NET, exceptions are used to signal errors or exceptional conditions during program execution. Proper exception handling allows you to gracefully respond to errors and prevent your application from crashing.

Here’s a basic example of exception handling in C#:

try
{
  // Code that may throw an exception
  int result = 10 / 0; // Division by zero
}
catch (DivideByZeroException ex)
{
  // Handle the exception
  Console.WriteLine("An error occurred: " + ex.Message);
}

In this example, we attempt to divide a number by zero, which would result in a `DivideByZeroException`. The `try-catch` block allows us to catch and handle the exception, preventing the application from crashing…
