In what situations and how do you use the try-catch block in code for exception handling?

The try-catch block is used for handling exceptions that may occur during program execution to prevent crashes and respond appropriately to errors.

When to use:

• When working with operations that may throw exceptions (e.g., file handling, network, database).
• When you need to handle an error and continue program execution.
• For logging errors or informing the user.

How to use:

try
{
    // Code that may throw an exception
    int result = 10 / divisor; // if divisor = 0, an exception will occur
}
catch (DivideByZeroException ex)
{
    // Handling specific exception
    Console.WriteLine("Division by zero is not possible.");
}
catch (Exception ex)
{
    // Handling all other exceptions
    Console.WriteLine("An error occurred: " + ex.Message);
}
finally
{
    // Code that will run in any case
    Console.WriteLine("Operation completed.");
}

Tips:

• Do not use try-catch for controlling program logic, only for handling truly exceptional situations.
• Handle specific exceptions to avoid hiding other errors.
• Use finally to release resources if needed.
