WPF c＃SendKeys到另一个Windows

Question

我想将密钥从WPF发送到另一个窗口（例如编辑器）

我找到了这个Methode

public static class SendKeys
{
    public static void Send(Key key)
    {
        if (Keyboard.PrimaryDevice != null)
        {
            if (Keyboard.PrimaryDevice.ActiveSource != null)
            {
                var e1 = new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, Key.Down) { RoutedEvent = Keyboard.KeyDownEvent };
                InputManager.Current.ProcessInput(e1);
            }
        }
    }
}

，但它不起作用：/

所以我从我的主程序中调用它

  

SendKeys.Send（Key.D7）;

在这种情况下，WindowsForms不是替代方法：/

Answer 1

使用传递的key参数代替Key.Down。

这很好用：

public partial class MainWindow : Window
{
    public MainWindow()
    {
        this.Loaded += OnLoaded;
        this.KeyDown += OnKeyDown;
        InitializeComponent();
    }
    private void OnLoaded(object sender, RoutedEventArgs routedEventArgs)
    {
        SendKeys.Send(Key.A);
        SendKeys.Send(Key.B);
        SendKeys.Send(Key.C);
        SendKeys.Send(Key.D);
        SendKeys.Send(Key.LeftCtrl);
    }

    private void OnKeyDown(object sender, KeyEventArgs e)
    {
        MessageBox.Show("Key pressed: " + e.Key);
    }
}

public static class SendKeys
{
    public static void Send(Key key)
    {
        if (Keyboard.PrimaryDevice != null)
        {
            if (Keyboard.PrimaryDevice.ActiveSource != null)
            {
                var e1 = new KeyEventArgs(Keyboard.PrimaryDevice, Keyboard.PrimaryDevice.ActiveSource, 0, key) { RoutedEvent = Keyboard.PreviewKeyDownEvent };
                InputManager.Current.ProcessInput(e1);
            }
        }
    }
}
