A FileSystemEvents object that will be used to raise events. Cannot be a null reference (Nothing in Visual Basic).
userData
Opaque data that will be passed back to the event handler when an event is raised.
overwrite
true if existing data for the item should be replaced; false if existing data should be preserved, appending new data at the end.
share
A System.IO.FileShare constant that determines how the file will be shared with different processes.
Return Value
A System.IO.Stream object that can be used to write data to the file.
Remarks
The returned stream is guaranteed to be writable, but may or may not be seekable.
The share parameter allows you to control how the file is shared by different processes. Some specializations of the AbstractFile class may not support any or all of the values defined in this enumeration. In this case, an exception is thrown.
Some File implementations may not support appending or overwriting. In this case, an exception is thrown.
If there is no existing data, the parameter overwrite is ignored.
If the file does not exist, the CreateWrite method should be used to retrieve the stream rather than OpenWrite.
