Name
FileMode
Synopsis
This enumeration allows you to
specify how you want to open a file.
If you use Create
, and the file already exists, an
IOException
is thrown. If you use
CreateNew
, any file that currently exists is
overwritten. OpenOrCreate
indicates that if a file
already exists, it must be opened; otherwise, a new file must be
created. Similarly, Truncate
indicates that the
file must be opened and all its data erased (writing then begins at
the first byte in the file). Append
indicates that
the file must be opened and the “file
position” set to the end of the file (the opposite
of Truncate).
public enum FileMode { CreateNew = 1, Create = 2, Open = 3, OpenOrCreate = 4, Truncate = 5, Append = 6 }
