Question

我是WPF的新手。我有一个带有数据网格的WPF窗口，它会在双击时启动进程。这项工作很棒，但是当我在平板电脑（使用Windows 7）中使用触摸屏执行此操作时，过程永远不会发生。所以我需要使用触摸事件模拟双击事件。有人可以帮我这么做吗？

有关如何模拟鼠标单击（在Windows窗体中），请参阅How to simulate Mouse Click in C#?，但它可以在WPF中运行：

using System.Runtime.InteropServices;

namespace WpfApplication1
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }

    [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
    public static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint cButtons, uint dwExtraInfo);

    private const int MOUSEEVENTF_LEFTDOWN = 0x02;
    private const int MOUSEEVENTF_LEFTUP = 0x04;
    private const int MOUSEEVENTF_RIGHTDOWN = 0x08;
    private const int MOUSEEVENTF_RIGHTUP = 0x10;

    public void DoMouseClick()
    {
         //Call the imported function with the cursor's current position
        int X = //however you get the touch coordinates;
        int Y = //however you get the touch coordinates;
        mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, X, Y, 0, 0);
    }
}
}

首先添加鼠标事件点击功能：

/// <summary>
/// Returns mouse click.
/// </summary>
/// <returns>mouseeEvent</returns>
public static MouseButtonEventArgs MouseClickEvent()
{
    MouseDevice md = InputManager.Current.PrimaryMouseDevice;
    MouseButtonEventArgs mouseEvent = new MouseButtonEventArgs(md, 0, MouseButton.Left);
    return mouseEvent;
}

向您的某个WPF控件添加click事件：

private void btnDoSomeThing_Click(object sender, RoutedEventArgs e)
{
    // Do something
}

最后，从任何函数调用click事件：

btnDoSomeThing_Click(new object(), MouseClickEvent());

要模拟双击，请添加一个双击事件，如PreviewMouseDoubleClick，并确保所有代码都在单独的函数中启动：

private void lvFiles_PreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    DoMouseDoubleClick(e);
}

private void DoMouseDoubleClick(RoutedEventArgs e)
{
    // Add your logic here
}

要调用双击事件，只需从另一个函数（如KeyDown）调用它：

private void someControl_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
    if (e.Key == Key.Enter)
        DoMouseDoubleClick(e);
}

使用touchDown模拟Datagrid中的双击事件
