OpenAccess Enumeration

Indicates how to open a file when calling file-access functions.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public enum class OpenAccess

Member nameDescription
DefaultRead and write access permitted. This is the default.
ReadRead access permitted.
ReadWriteRead and write access permitted.
WriteWrite access permitted.

When you call file access-related functions, you can use enumeration members in your code in place of the actual values.

The OpenAccess enumeration defines constants used to identify whether a file can be read from (Read), written to (Write), or both (ReadWrite). A file opened for Read access cannot be modified, only read from. The following table lists the OpenAccess enumeration members.

When performing file I/O operations, the My.Computer.FileSystem object provides greater performance and ease of use than legacy file I/O methods. For more information, see FileSystem object.
