Exception | Description |
---|---|
System.ArgumentNullException |
A This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception. |
System.IO.IOException | An I/O error has occurred. This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately. |
System.NotSupportedException | An invoked method is not supported at all, or is not supported with the parameters used to create the object. |
System.Security.SecurityException | A security error was detected. This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately. |
System.UnauthorizedAccessException | The operating system has denied access because of an I/O error or a specific type of security error. This is an operation error that depends on factors external to your program, and thus cannot be always avoided. Your code must handle it appropriately. |
This method is similar in purpose to System.IO.FileInfo.CreateText or System.IO.FileInfo.AppendText, but is generalized for any kind of writable file info, not just files in the physical file system.
