Learning Path Details

Foundation in C#: Debugging from Tim Corey

Description:

Module 3 of the Complete Foundation in C# Course Series, the focus is on debugging our applications, including use of breakpoints and exception handling. At the end of the module, we do a mini project to demonstrate what we have learned.

Key Takeaways:

We learn how to use the Visual Studio debugger to debug our applications, including the use of breakpoints, conditional breakpoints, and proper exception handling.

Technologies Learned:

  • .NET;
  • .NET Framework;
  • .NET Framework 4.7.2;
  • C#;
  • Child Classes of the Exception Class;
  • Exceptions (Class);
  • Handling Exceptions;
  • Multiple Catch statements;
  • try/catch;
  • try/catch/finally;
  • Using Breakpoints;
  • Visual Studio Debugger;

Practice Projects

Advanced Breakpoints

Description:

The homework from the Lesson 5, Advanced Breakpoints, of Module 3, Debugging, of the Complete Foundation in C# Course Series from Tim Corey. We are to create a Console Application that loops from 1 to 100. Throw an exception on 73. Use a breakpoint to break before the breaking situation.

Technologies Used:
  • .NET;
  • .NET Framework;
  • .NET Framework 4.8;
  • C#;
Code Snippet:
using System;

namespace ConsoleUI
{
	internal class Program
	{
		private static void Main()
		{
			Looper();
			_ = Console.ReadLine();
		}

		private static void Looper()
		{
			int total = 0;

			for ( int i = 1; i <= 100; i++ )
			{
				total += i;
				if ( i == 73 )
				{
					throw new Exception();
				}
			}
		}
	}
}

Advanced Exceptions

Description:

The homework from the Lesson 4, Advanced Exceptions, of Module 3, Debugging, of the Complete Foundation in C# Course Series from Tim Corey. We are to create a Console Application that throws an exception in a method that we can catch in the main method.

Technologies Used:
  • .NET;
  • .NET Framework;
  • .NET Framework 4.8;
  • C#;
  • Console Application;
Code Snippet:
using System;

namespace ConsoleUI
{
	internal class Program
	{
		private static void Main()
		{
			try
			{
				ExceptionGenerator();
			}
			catch ( NotImplementedException ex )
			{
				Console.WriteLine("You did not implement a mathod.");
				Console.WriteLine(ex);
			}
			catch ( Exception ex )
			{
				Console.WriteLine("A general exception occurred");
				Console.WriteLine(ex);
			}
			finally
			{
				Console.WriteLine("Clean up code: I always run!");
			}

			_ = Console.ReadLine();
		}

		private static void ExceptionGenerator()
		{
			throw new NotImplementedException();
		}
	}
}

Handling Exceptions

Description:

The homework from the Lesson 3, Handling Exceptions, of Module 3, Debugging, of the Complete Foundation in C# Course Series from Tim Corey. We are to create a Console Application with a for loop that throws an exception after five iterations. Catch the exception.

Technologies Used:
  • .NET;
  • .NET Framework;
  • .NET Framework 4.8;
  • C#;
  • Console Application;
Code Snippet:
using System;

namespace ConsoleUI
{
	internal class Program
	{
		private static void Main()
		{
			int[] numbers = new int[] { 1, 42, 34, 56, 13 };

			for ( int i = 0; i <= numbers.Length; i++ )
			{
				try
				{
					Console.WriteLine($"The number at position {i} is {numbers[i]}");
				}
				catch ( Exception ex )
				{
					Console.WriteLine("We had an error");
					Console.WriteLine(ex);
				}
			}

			_ = Console.ReadLine();
		}
	}
}

Using Breakpoints

Description:

The homework from the Lesson 2, Using Breakpoints, of Module 3, Debugging, of the Complete Foundation in C# Course Series from Tim Corey. We are to create a Console Application with a for loop that multiplies a number by five and adds it to the total each time. Step through the code.

Technologies Used:
  • .NET;
  • .NET Framework;
  • .NET Framework 4.8;
  • C#;
  • Console Application;
Code Snippet:
using System;

namespace ConsoleUI
{
	internal class Program
	{
		private static void Main()
		{
			for ( int i = 1; i < 50; i *= 5 )
			{
				Console.WriteLine($"The value of i is {i}");
			}

			_ = Console.ReadLine();
		}
	}
}
