Description: Re-throw is a keyword used in C# to throw an exception again after it has been caught. This action is fundamental in error management, as it allows developers to handle exceptions more effectively. By using ‘throw;’ without an argument, the programmer can catch an exception, perform some action, such as logging the error or cleaning up resources, and then throw the same exception again so that it can be handled at a higher level in the call stack. This is especially useful in complex applications where different layers of the application may need to know about and react to the same error. The syntax for re-throwing an exception in C# is simple: the ‘throw’ keyword is used without specifying the exception, which preserves the original call stack information. This feature not only improves error traceability but also allows for better separation of concerns in the code, keeping error handling logic centralized while allowing other components of the application to respond appropriately to exceptions.
