C sharp - Exception in C#

Definition:
An exception in C# is an error that occurs during program execution (runtime) that disrupts the normal flow of the application.

When an exception occurs, C# creates an exception object and passes it to the runtime system to handle it. If not handled, the program will crash.

Common Causes of Exceptions:

Dividing by zero
Accessing an invalid array index
Opening a file that doesn’t exist
Invalid type conversions

Exception Handling Keywords in C#:

Keyword	Description
`try`	Block where you write code that may cause an exception
`catch`	Block that handles the exception
`finally`	Block that always executes (used for cleanup)
`throw`	Used to manually throw an exception

Example:

try {
    int a = 10;
    int b = 0;
    int result = a / b; // Causes DivideByZeroException
}
catch (DivideByZeroException e) {
    Console.WriteLine("Error: " + e.Message);
}
finally {
    Console.WriteLine("This block always runs.");
}

Benefits of Exception Handling:

Prevents application crashes
Makes debugging easier
Allows custom error messages and recovery
Keeps code clean and readable
