How do I programmatically press Enter?

Question

I have a C# console program which starts calculator and simulates key presses. How do I programmatically press Enter?

    [DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
    public static extern IntPtr FindWindow(string lpClassName,
        string lpWindowName);

    // Activate an application window.
    [DllImport("USER32.DLL")]
    public static extern bool SetForegroundWindow(IntPtr hWnd);

    // Send a series of key presses to the Calculator application. 
    private void StartCalculator()
    {
        Process.Start("calc.exe");
        IntPtr calculatorHandle = FindWindow("CalcFrame","Calculator");

        if (calculatorHandle == IntPtr.Zero)
        {
            return;
        }

        SetForegroundWindow(calculatorHandle);
        SendKeys.SendWait("111");
        SendKeys.SendWait("*");
        SendKeys.SendWait("11");
        SendKeys.SendWait("=");
        SendKeys.SendWait(" ");//how press enter?
    }

Taken from SendKeys.Send Method

SendKeys.SendWait("~"); // How to press enter?

or

SendKeys.SendWait("{ENTER}"); // How to press enter?

I believe the documentation states that it's `"{ENTER}"` you need, not `"ENTER"` – Jason Evans Aug 20 '14 at 14:47

@JasonEvans it uses {Enter} :) – nsgocev Aug 20 '14 at 14:48
You link to Send(), but tell us to use SendWait(). Why? – Maxter Sep 11 '20 at 14:19
