Question

我有一个C＃控制台程序，它启动计算器并模拟按键。如何以编程方式按 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?
    }

Answer 1

取自SendKeys.Send Method

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

或

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

如何以编程方式按Enter键？
