FileStream^ s2 = gcnew FileStream( name, FileMode::Open, FileAccess::Read, FileShare::Read );
FileStream s2 = new FileStream(name, FileMode.Open, FileAccess.Read, FileShare.Read);

Remarks
For an example of creating a file and writing text to a file, see How to: Write Text to a File. For an example of reading text from a file, see How to: Read Text from a File. For an example of reading from and writing to a binary file, see How to: Read and Write to a Newly Created Data File.
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.
