OpenShare Enumeration

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

Remarks

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

The OpenShare enumeration defines constants that specify whether or not other processes can access the file while your application has it open. The following table lists the OpenShare 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 My.Computer.FileSystem Object.
