public override void newmethod (string _filename, string _mode);

override this.newmethod : string * string -> unit

Public Overrides Sub newmethod (_filename As String, _mode As String)

Parameters

_filename

String

The mode to use to create the instance of the BinaryIo class.

_mode

The mode to use to create the instance of the BinaryIo class.

Remarks

If an attacker can control input to the new method, a security risk exists. Therefore, this method runs under class. Make sure that the user has development privileges by setting the security key to SysDevelopment on the control that calls this method.

This example uses the BinaryIo class to read data from the ExampleFile text file.
