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
}
