检测当前程序是否有人操作应该再实际中还是有用的。最简单的方法时判断鼠标位置是否改变了。winform中也是一样。直接看代码：
public class CheckUsedManager { public static event EventHandler TimeToFinishedEvent = null; private static DispatcherTimer checkUsedTimer = new DispatcherTimer(); private static Point mousePosition = GetMousePoint(); static CheckUsedManager() { checkUsedTimer.Interval = TimeSpan.FromSeconds(秒数); checkUsedTimer.Tick += new EventHandler(CheckUsedTimer_Tick); checkUsedTimer.Start(); } static void CheckUsedTimer_Tick(object sender, EventArgs e) { if (!HaveUsedTo()) { if (TimeToFinishedEvent != null) { TimeToFinishedEvent(null, null); } } } private static bool HaveUsedTo() { Point point = GetMousePoint(); if (point == mousePosition) { return false; } mousePosition = point; return true; } [StructLayout(LayoutKind.Sequential)] private struct MPoint { public int X; public int Y; public MPoint(int x, int y) { this.X = x; this.Y = y; } } [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern bool GetCursorPos(out MPoint mpt); /// <summary> /// 获取当前屏幕鼠标位置 /// </summary> /// <returns></returns> public static Point GetMousePoint() { MPoint mpt = new MPoint(); GetCursorPos(out mpt); Point p = new Point(mpt.X, mpt.Y); return p; } } 然后绑定到该类的事件即可。如下用WPF实现的完整代码：
判断的类：
public class CheckUsedManager { public static event EventHandler TimeToFinishedEvent = null; private static DispatcherTimer checkUsedTimer = new DispatcherTimer(); private static Point mousePosition = GetMousePoint(); static CheckUsedManager() { checkUsedTimer.Interval = TimeSpan.FromSeconds(ReadConfig.AutoCheckUsedTime); checkUsedTimer.Tick += new EventHandler(CheckUsedTimer_Tick); checkUsedTimer.Start(); } static void CheckUsedTimer_Tick(object sender, EventArgs e) { if (!HaveUsedTo()) { if (TimeToFinishedEvent != null) { TimeToFinishedEvent(null, null); } } } private static bool HaveUsedTo() { Point point = GetMousePoint(); if (point == mousePosition) { return false; } mousePosition = point; return true; } [StructLayout(LayoutKind.Sequential)] private struct MPoint { public int X; public int Y; public MPoint(int x, int y) { this.X = x; this.Y = y; } } [DllImport("user32.dll", CharSet = CharSet.Auto)] private static extern bool GetCursorPos(out MPoint mpt); /// <summary> /// 获取当前屏幕鼠标位置 /// </summary> /// <returns></returns> public static Point GetMousePoint() { MPoint mpt = new MPoint(); GetCursorPos(out mpt); Point p = new Point(mpt.X, mpt.Y); return p; } }
读配置里的时间：
public class ReadConfig { /// <summary> /// 检测是否使用间隔时间 /// </summary> public static int AutoCheckUsedTime { get { int time = 10; try { string timeStr = ConfigurationManager.AppSettings["AutoCheckUsedTime"]; if (string.IsNullOrEmpty(timeStr)) { timeStr= "10"; } time = int.Parse(timeStr); } catch { } return time; } } } 配置App.config：
<?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="AutoCheckUsedTime" value="10"/> </appSettings> </configuration>
界面调用：
public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); CheckUsedManager.TimeToFinishedEvent -= new EventHandler(CheckUsedManager_TimeToFinishedEvent); CheckUsedManager.TimeToFinishedEvent += new EventHandler(CheckUsedManager_TimeToFinishedEvent); } void CheckUsedManager_TimeToFinishedEvent(object sender, EventArgs e) { MessageBox.Show("无人使用！"); } } 结果：
