| 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. |
For an example of creating a file and writing text to a file, see Writing Text to a File. For an example of reading text from a file, see Reading Text from a File. For an example of reading from and writing to a binary file, see Reading and Writing to a Newly Created Data File.
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.
