C# Exception Handling

Throwing more than three or four types of exceptions is considered poor coding style.

A finally block executes code that is necessary regardless of whether an exception was thrown.

When an exception is rethrown, it propagates up the call stack to be caught by a higher-level handler.

Catch blocks should be ordered from specific exceptions to general exceptions to avoid masking more specific handlers.

Unreachable code is also known as dead code, as it cannot be executed by the program.

Generalizing exception types makes the code more maintainable by reducing dependencies on specific exception classes.

Avoid throwing too many types of exceptions to keep the code simple and easy to maintain.

Following best practices in exception handling makes the code more maintainable and robust, ensuring that errors are handled gracefully.

The throw keyword in C# is used to raise an exception.

When a method from another class throws an exception, the calling program can catch the exception to handle it.

Multiple statements can be placed within a try block to monitor for exceptions.

Catch clauses should be placed from most specific to most generic to handle exceptions correctly.

Object-oriented exception-handling techniques allows developers to deal with exceptions appropriately by deciding how to handle them based on the object state and type.

When multiple catch blocks are examined in sequence, a match is found for the exception that occurred, and that block is executed.

Yes, multiple catch clauses can be used to handle various exceptions and provide specific error handling for each.

It is important to handle exceptions appropriately to decide how to respond to each exception effectively.

The purpose of the NegativeBalanceException constructor is to throw an exception when the account balance is negative.

In the provided code, when the balance is set to a negative value, a NegativeBalanceException is thrown.

Rethrowing an exception in a catch block allows the calling method to handle the problem or take further action.

An exception object is instantiated from any condition that happens infrequently and disrupts the normal flow of the program.

After an exception object is instantiated, it is thrown to signal that an error has occurred.

Let the calling method handle the problem, allows for centralized error handling and better separation of concerns.

Using custom exception classes in C# allows you to provide more specific information about the exception that occurred, such as custom error codes or additional context.

The purpose of the constructors for user-defined exceptions in C# is to allow you to throw an exception with a custom message and any additional data that might be useful for debugging and error handling.
