我想编写一个计算窗口中鼠标点击次数的应用程序。经过一些研究,我发现了这个库:MouseKeyHook 我创建了wpf应用程序并复制了示例代码:
public partial class MainWindow : Window
{
private IKeyboardMouseEvents m_GlobalHook;
public MainWindow()
{
InitializeComponent();
Subscribe();
}
public void Subscribe()
{
// Note: for the application hook, use the Hook.AppEvents() instead
m_GlobalHook = Hook.GlobalEvents();
m_GlobalHook.MouseDownExt += GlobalHookMouseDownExt;
m_GlobalHook.KeyPress += GlobalHookKeyPress;
}
private void GlobalHookKeyPress(object sender, KeyPressEventArgs e)
{
Console.WriteLine("KeyPress: \t{0}", e.KeyChar);
}
private void GlobalHookMouseDownExt(object sender, MouseEventExtArgs e)
{
Console.WriteLine("MouseDown: \t{0}; \t System Timestamp: \t{1}", e.Button, e.Timestamp);
// uncommenting the following line will suppress the middle mouse button click
// if (e.Buttons == MouseButtons.Middle) { e.Handled = true; }
}
public void Unsubscribe()
{
m_GlobalHook.MouseDownExt -= GlobalHookMouseDownExt;
m_GlobalHook.KeyPress -= GlobalHookKeyPress;
//It is recommened to dispose it
m_GlobalHook.Dispose();
}
}
没有错误或警告,应用程序会检测键入的点击次数和键。但只需点击几下,我就会收到错误消息:
有时只需点击几下,有时会在100次点击后显示此错误(MouseDown事件 - 鼠标左键)。此外,当错误发生时,我的光标会在几秒钟内显着减慢。

尝试在与main不同的线程中创建该Hook对象。在DllMain中运行并阻止GUI的代码经常会出现此问题。
