FileShare Enumeration
Contains constants for controlling the kind of access other FileStream objects can have to the same file.
Namespace: System.IO
Assembly: mscorlib (in mscorlib.dll)
Syntax
public enum FileShare
Remarks
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
A typical use of this enumeration is to define whether two processes can simultaneously read from the same file. For example, if a file is opened and Read is specified, other users can open the file for reading but not for writing.
A FileShare parameter is specified in some of the constructors for FileStream, IsolatedStorageFileStream, and in some of the Open methods of File and FileInfo to control how a file is opened.
Version Information
Available in the .NET Micro Framework versions 3.0, 4.0, and 4.1.
Members
| Member name | Description | |
|---|---|---|
| Delete | Allows subsequent deleting of a file. | |
| None | Declines sharing of the current file. Any request to open the file (by this process or another process) will fail until the file is closed. | |
| Read | Allows subsequent opening of the file for reading. If this flag is not specified, any request to open the file for reading (by this process or another process) will fail until the file is closed. However, even if this flag is specified, additional permissions might still be needed to access the file. | |
| ReadWrite | Allows subsequent opening of the file for reading or writing. If this flag is not specified, any request to open the file for reading or writing (by this process or another process) will fail until the file is closed. However, even if this flag is specified, additional permissions might still be needed to access the file. | |
| Write | Allows subsequent opening of the file for writing. If this flag is not specified, any request to open the file for writing (by this process or another process) will fail until the file is closed. However, even if this flag is specified, additional permissions might still be needed to access the file. |
