Description: The file not found exception is a type of error that is thrown when a program attempts to access a file that does not exist at the specified location. This exception, represented by the ‘FileNotFoundException’ class, is part of the ‘System.IO’ namespace in the .NET framework and is used to handle situations where a required file cannot be located. The importance of this exception lies in its ability to allow developers to manage errors effectively, ensuring that applications do not crash unexpectedly and that clear error messages can be provided to users. By catching this exception, programmers can implement alternative logic, such as prompting the user to select a different file or creating a new file if the original file is unavailable. The ‘FileNotFoundException’ also includes additional information, such as the name of the file that could not be found, which facilitates debugging and error handling. In summary, this exception is fundamental to the robustness and usability of applications in many programming environments, allowing for proper handling of common situations that may arise during file manipulation.
