Why is File.Delete() Throwing an UnauthorizedAccessException?

Troubleshooting File Deletion Errors: UnauthorizedAccessException in C#

The File.Delete() method in C# can throw an UnauthorizedAccessException, indicating insufficient permissions to delete a file. This exception arises from several scenarios:

1. Insufficient Permissions: The user account or process running the code lacks the necessary file system permissions to delete the target file.

2. File in Use: The file is currently open and being used by another application. Close all programs accessing the file before attempting deletion.

3. Incorrect Path: The provided path points to a directory instead of a file. File.Delete() only works on files, not directories. Use Directory.Delete() for directories.

4. Read-Only Attribute: The file is marked as read-only. Change the file's attributes to remove the read-only flag before deletion.

This comprehensive understanding helps pinpoint the exact cause and implement the appropriate solution to successfully delete the file.
