The throw statement in C# is used to explicitly generate an exception. It allows developers to create custom error conditions and control program flow when something goes wrong.<\/p>\n\n\n\n
The throw statement is used to raise an exception manually in a program. It can be used with built-in exceptions or custom exceptions defined by the developer.<\/p>\n\n\n\n
When a throw statement is executed, it immediately stops the normal flow of the program and transfers control to the nearest catch block that can handle the exception.<\/p>\n\n\n\n
The throw keyword is followed by an exception object. This object contains information about the error that occurred.<\/p>\n\n\n\n
Developers often use throw inside conditions to validate input and stop execution when invalid data is detected.<\/p>\n\n\n\n
The throw statement can also be used inside a catch block to rethrow an exception after partial handling, allowing it to be processed further up the call stack.<\/p>\n\n\n\n
It helps in enforcing rules, validating data, and ensuring that invalid operations are properly reported and handled.<\/p>\n\n\n\n
The throw statement is used in banking systems, form validation, API development, and data processing where invalid input must be rejected.<\/p>\n\n\n\n
