   FileShare share,
   FileOptions fileOptions
)

Parameters

session

A reference to a FileSystemEventsSession object which is responsible for raising all events that occur during the process.

overwrite

true if existing data for the file 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 by different processes.

fileOptions

Return Value

The returned stream should be guaranteed to be writable, but does not have to be seekable.

The share parameter should allow control over how the file is shared by different processes. If the values defined in this enumeration are not supported, an exception should be thrown.

If the File implementation does not support appending or overwriting, an exception should be thrown.

If there is no existing data, the parameter overwrite should be ignored.
