enum System.IO.FileOptions

Assembly: System.Runtime

Represents advanced options for creating a <see cref="T:System.IO.FileStream" /> object.

Values

WriteThrough

Indicates that the system should write through any intermediate cache and go directly to disk.

None

Indicates that no additional options should be used when creating a <see cref="T:System.IO.FileStream" /> object.

Encrypted

Indicates that a file is encrypted and can be decrypted only by using the same user account used for encryption.

DeleteOnClose

Indicates that a file is automatically deleted when it is no longer in use.

SequentialScan

Indicates that the file is to be accessed sequentially from beginning to end. The system can use this as a hint to optimize file caching. If an application moves the file pointer for random access, optimum caching may not occur; however, correct operation is still guaranteed. Specifying this flag can increase performance in some cases.

RandomAccess

Indicates that the file is accessed randomly. The system can use this as a hint to optimize file caching.

Asynchronous

Indicates that a file can be used for asynchronous reading and writing.
