C # Analog Keys

Make sure that you have referenced the System.Windows.Forms DLL file.

System.Windows.Forms.SendKeys.Send ("A");

Emit a signal of a A.

Ctrl = ^
Shift = +
Alt =%

For example, you want to send a CTRL + A (select All) to a program.
The

System.Windows.Forms.SendKeys.Send ("^a");

Other special buttons such as "F10"
Enter, etc., please use curly braces to expand.
For example, send a carriage return

System.Windows.Forms.SendKeys.Send ("{ENTER}");

Special attention:
{PRTSC} (Print screen) key cannot be sent to the window. Can only be sent to handle 0. But the effect is the same, still able to intercept the screen.
