Error Handling (try-catch)

In this lesson you will learn error handling with try-catch in C#, so an unexpected failure does not bring your whole program down. This is for anyone searching for "C# try catch how to use".

try / catch catches errors (exceptions) so the program keeps running. It works like insurance: you decide in advance what to do if something goes wrong.

The sample code tries to divide by zero inside the try block and catches only that specific kind of failure with catch (DivideByZeroException). Naming the exception type keeps you from accidentally swallowing errors you did not anticipate.

A common stumbling block for beginners is that the calling code carries on without knowing an exception exists. That leads to the program stopping in an unexpected place, so it needs care.

In real-world development, splitting your catch blocks by exception type lets you write a response tailored to each cause.
