In some applications written using Rebex SSH Shell or Rebex Telnet that utilize a terminal emulation or virtual terminal, it might be useful to be able to send Ctrl+C sequence programatically. And although this is easy when you know how Ctrl+C actually behaves in Windows, it is definitely not straightforward enough. So this is how you do this:
C#:
terminalControl.SendToServer(new ConsoleKeyInfo('\x3', ConsoleKey.C, false, false, true));
VB.NET:
terminalControl.SendToServer(New ConsoleKeyInfo(Convert.ToChar(3), ConsoleKey.C, False, False, True))
(where terminalControl is an instance of TerminalControl or VirtualTerminal class)
This code creates a ConsoleKeyInfo that simulates a key with ASCII code 3 (ETX special character), console key ‘C’ and a pressed Ctrl key. This simulated keystroke is then sent to the server using the SendToServer method.
UPDATE: Are your curious why using '\x3' equals to sending Ctrl+C? Do you want to know other common control codes? Check the table in following Wikipedia article: wikipedia.org/wiki/ASCII#ASCII_control_characters
