You can call the Win32 api to generate key and mouse events or use the SendKeys API. Each language in .Net should have access to the underlying win32 api.

There is no direct way from C# but I found this at msdn. It shows how to use SendKeys to automate key presses. You will have to identify the target window, find the key codes you want and generate a keybd_event.

VK_KEY codes - VK_CONTROL (0x11)
How to use keybd_event Function

Have you done the events in the right order? 

keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYDOWN, 0);//press ctrl
keybd_event(0x41, 0, KEYEVENTF_KEYDOWN, 0);//hex 'A'
keybd_event(0x41, 0, KEYEVENTF_KEYUP, 0);//hex 'A'
keybd_event(VK_CONTROL, 0, KEYEVENTF_KEYUP, 0); //release ctrl
