How do I programmatically press Enter?

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?
    }

If you need to relocate to a path then that time you need a dialog handle for that dialog box and use sendkeys like the below:

IntPtr dialogHandle = FindWindow("#32770", null);

if (dialogHandle != IntPtr.Zero)
{
    string filepath = "path you wanted to relocate";
    SendKeys.SendWait(Path.Combine(filePath,"{ENTER}"));
}

Taken from SendKeys.Send Method

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

or 

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