In what cases is the try block used in code for exception handling?

The try block in C# is used to wrap code that may throw an exception (an error during execution). The main goal is to catch these exceptions and handle them so that the program does not terminate abruptly.

It is used in cases where:

• Working with external resources (files, network, database), where errors are possible.
• Performing operations that may lead to errors (division by zero, type conversion).
• Ensuring that certain code is executed after the attempt (together with finally).

Example:

try {
    int result = 10 / divisor;
} catch (DivideByZeroException ex) {
    Console.WriteLine("Division by zero is not possible.");
}

Thus, the try block helps make the code more reliable and controllable.
