FileAccess Enum
Definition
Defines constants for read, write, or read/write access to a file.
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

Fields
| Read | 1 | Read access to the file. Data can be read from the file. Combine with |
| ReadWrite | 3 | Read and write access to the file. Data can be written to and read from the file. |
| Write | 2 | Write access to the file. Data can be written to the file. Combine with |
Examples
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);
Dim s2 As 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.
