Enumeration Type Documentation

FileAccess

enum System::IO::FileAccess

strong

Specifies the type of access when opening the file.

Enumerator
Read	Read-only access.
Write	Write-only access.
ReadWrite	Read and write access.

FileAttributes

enum System::IO::FileAttributes

strong

Represents attributes of a directory or a file.

Enumerator
Archive	The filesystem entity is a candidate for removal or backup.
Compressed	The filesystem entity is compressed.
Device	Not used.
Directory	The filesystem entity is a directory.
Encrypted	The filesystem entity is encrypted.
Hidden	The filesystem entity is hidden.
IntegrityStream	The filesystem entity contains data integrity support.
Normal	The filesystem entity is a file that has no special attributes.
NotContentIndexed	The filesystem entity will not be indexed by the content indexing service.
NoScrubData	The filesystem entity is not included in the data integrity scan.
Offline	The filesystem entity is offline and its data is not immediately available.
ReadOnly	The filesystem entity is read-only.
ReparsePoint	The filesystem entity is a file that contains a reparse point.
SparseFile	The filesystem entity is a sparse file.
System	The filesystem entity is a system file.
Temporary	The filesystem entity is a temporary file.
Invalid	Invalid value.

FileMode

enum System::IO::FileMode

strong

Specifies how a file should be opened.

Enumerator
CreateNew	Create a new file. If the file already exists, an exception is thrown.
Create	Create a new file. If the file already exists, it is overwritten.
Open	Open an existing file. If the file does not exist, an exception is thrown.
OpenOrCreate	Open an existing file or create a new one if it does not exist.
Truncate	Open an existing file and truncate it so that it is empty. If the file does not exist, an exception is thrown.
Append	Open an existing file and seek to the end of it or create a new one if it does not exist.

FileOptions

enum System::IO::FileOptions

strong

Represents advanced options for creating FileStream object.

Enumerator
None	No additional options.
Encrypted	The file is encrypted.
DeleteOnClose	The file should be automatically deleted when it is not in use anymore.
SequentialScan	The file shoud be accesses sequentially.
RandomAccess	The file is accessed randomly.
Asynchronous	The file can be used for asynchronous I/O operations.
WriteThrough	All writes should go directly to the disk bypassing any intermediate cache.

FileShare

enum System::IO::FileShare

strong

Specifies what kind of access other FileStream objects can have to a file being opened.

Enumerator
None	No access.
Read	Read-only access.
Write	Write-only access.
ReadWrite	Read and Write access.
Delete	The file can be deleted.
Inheritable	NOT SUPPORTED.

SearchOption

enum System::IO::SearchOption

strong

Specifies a search should be performed only in the current directory, or in the current directory and all its subdirectories.

Enumerator
AllDirectories	Search in the current directory and all its subdirectories.
TopDirectoryOnly	Search in the current directory only.

SeekOrigin

enum System::IO::SeekOrigin

strong

Specifies the reference position in the stream relative to which the position to seek to is specified.

Enumerator
Begin	Beginning of the stream.
Current	Current stream position.
End	End of the stream.
