How is Exception Handling implemented in C#?

Exception Handling in C#

Exception handling in C# is implemented using a combination of keywords and constructs that allow you to handle and manage errors that may occur during program execution. Here's how it works:

1. try-catch blocks

The try block is used to enclose code that may potentially throw an exception. If an exception occurs within the try block, the execution jumps to the corresponding catch block. Each catch block is designed to handle a specific type of exception.

try
{
    // Code that may throw an exception
    int result = 10 / 0; // Throws DivideByZeroException
}
catch (DivideByZeroException ex)
{
    // Handle the exception
    Console.WriteLine($"Error: {ex.Message}");
}

2. Exception types

C# provides a hierarchy of exception types, derived from the base class System.Exception. This allows you to catch specific exceptions or handle them more generally.

}
catch (ArgumentNullException ex)
{
    // Handle ArgumentNullException
}
catch (Exception ex)
{
    // Handle any other exception
}

3. throw statement
