Contains constants for controlling the kind of access other System.IO.FileStream objects can have to the same file.
Syntax
Remarks
For an example of creating a file and writing text to a file, see [<topic://cpconwritingtexttofile>]. For an example of reading text from a file, see [<topic://cpconreadingtextfromfile>]. For an example of reading from and writing to a binary file, see [<topic://cpconReadingWritingToNewlyCreatedDataFile>].
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 FileShare.Read is specified, other users can open the file for reading but not for writing.
A System.IO.FileShare parameter is specified in some of the constructors for System.IO.FileStream, System.IO.IsolatedStorage.IsolatedStorageFileStream, and in some of the Open methods of System.IO.File and System.IO.FileInfo to control how a file is opened.
Members
| Member Name | Description |
|---|---|
| Delete |
Allows subsequent deleting of a file. |
| Inheritable |
Makes the file handle inheritable by child processes. This is not directly supported by Win32. |
| 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. |
