Actually it gives you enough info

that's the first hit on google. I've never really worked with C# only a few small programs and even I can see at this page what it does you'll need to give a string as parameter and it'll send to the focused window so if you got your browser selected it'll send that key to the browser if you got another window selected it'll send it to that window.

so with:

Code:

		SendKeys.Send("{ENTER}");

you'll send a enter.

you can't use it in the background to it has limitations.

A much better method

Quote:

[DllImport("user32.dll")]
static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);

const uint WM_KEYDOWN = 0x0100;

public static void PostMsg()
{
Process[] processes = Process.GetProcessesByName(pName);
foreach (Process p in processes)
{
PostMessage(p.MainWindowHandle, WM_KEYDOWN, (int)Keys.Y, 0); //wParam is your key
}

For x64

[DllImport("user32.dll")]
public static extern IntPtr PostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);

That means

PostMessage(p.MainWindowHandle, (uint)WM_KEYDOWN, (int)Keys.Y, IntPtr.Zero);
