A FileAccess parameter is specified in many of the constructors for File, FileInfo, FileStream, and other constructors where it is important to control the kind of access users have to a file.
The following FileStream constructor grants read-only access to an existing file (FileAccess.Read).
FileStream^ s2 = gcnew FileStream( name, FileMode::Open, FileAccess::Read, FileShare::Read );
FileStream s2 = new FileStream(name, FileMode.Open,
FileAccess.Read, FileShare.Read);
var s2 : FileStream = new FileStream(name, FileMode.Open, FileAccess.Read, FileShare.Read);
