【CSharp】判断当前是否有人操作
作者:欣玉 / 发布于2015/11/4/ 588
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。

	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！");
	 }
	 }
试试其它关键字
　当前操作　
同语言下
可能有用的
