Fields

Read Read Read

Access the file stream in read-only mode.

Keep read-only file streams open only while your app is actively reading from the file. You can use multiple independent read-only streams to read a file. If the file is changed while you're reading it, subsequent read operations fail.

ReadWrite ReadWrite ReadWrite

Access the file stream in read/write mode.

A file supports a single stream for writing. Writing is non-transactional and occurs in place; that is, data is written immediately to the target file without using a temporary file. Use read/write mode only when you're ready to write immediately in order to avoid conflicts with other operations.
