What is exception handling?

Hi @LucasDev89
Managing runtime errors using try, catch, finally blocks.

that's a good idea!

Hi! 👋 Great question.

Exception handling in C# is the way your program deals with unexpected problems (like dividing by zero, missing files, or network errors) without crashing.

The most common pattern is the try / catch / finally block:

try
{
// Code that might cause an error
int result = 10 / 0;
}
catch (DivideByZeroException ex)
{
// This runs if an exception occurs
Console.WriteLine("You can’t divide by zero!");
}
finally
{
// This always runs (optional)
Console.WriteLine("Done!");
}

try → put the risky code here.

catch → handles the error if one happens.

finally → code that should always run (cleanup, closing files, etc.).

This way your program can recover gracefully instead of just stopping with a crash. 🚀
