c# 任务栏托盘图标鼠标进入MouseEnter和鼠标离开MouseLeave实现

c#的任务栏托盘图标控件NotifyIcon只有MouseMove事件，MouseMove事件刷新很快，很不好用，而且我们有时需要鼠标进入和离开的事件，但是不知道c#怎么回事，没有提供，那么就只能自己来处理了。

解决鼠标进入和离开的思路是：

1.通过MouseMove事件确定当前鼠标已经进入托盘图标的范围

2.进入后启动检测timer

3.定时检测托盘图标的位置和当前鼠标的位置，判断鼠标是否在托盘图标的范围内

主要难点：获取当前托盘图标的位置

获取托盘图标位置的思路：

1.查找到托盘图标所在的窗口

private IntPtr FindTrayToolbarWindow()
        {
            IntPtr hWnd = FindWindow("Shell_TrayWnd", null);
            if (hWnd != IntPtr.Zero)
            {
                hWnd = FindWindowEx(hWnd, IntPtr.Zero, "TrayNotifyWnd", null);
                if (hWnd != IntPtr.Zero)
                {

                    hWnd = FindWindowEx(hWnd, IntPtr.Zero, "SysPager", null);
                    if (hWnd != IntPtr.Zero)
                    {
                        hWnd = FindWindowEx(hWnd, IntPtr.Zero, "ToolbarWindow32", null);

                    }
                }
            }
            return hWnd;
        }

2.遍历窗口内的托盘图标

3.获取当前托盘图标的句柄，通过句柄得到这个托盘图标所关联的进程id

4.通过进程id比较获取到当前程序的托盘图标

5.拖过api获取当前托盘图标相对于它所在窗口的位置

6.获取窗口在整个屏幕中的位置，在计算出托盘图标相对于屏幕的位置

   2-6代码：

private bool FindNotifyIcon(IntPtr hTrayWnd, ref Rect rectNotify)
        {
            UInt32 trayPid = 0;
            Rect rectTray = new Rect();
            GetWindowRect(hTrayWnd, out rectTray);
            int count = (int) SendMessage(hTrayWnd, TB_BUTTONCOUNT, 0, IntPtr.Zero); //给托盘窗口发消息，得到托盘里图标

            bool isFind = false;
            if (count > 0)
            {
                GetWindowThreadProcessId(hTrayWnd, out trayPid); //取得托盘窗口对应的进程id
                //获取托盘图标的位置


                IntPtr hProcess = OpenProcess(ProcessAccess.VMOperation | ProcessAccess.VMRead | ProcessAccess.VMWrite,
                    false, trayPid); //打开进程，取得进程句柄

                IntPtr address = VirtualAllocEx(hProcess, //在目标进程中申请一块内存，放TBBUTTON信息

                TBBUTTON btnData = new TBBUTTON();
                TRAYDATA trayData = new TRAYDATA();

                //  Console.WriteLine("Count:"+count);

                var handel = Process.GetCurrentProcess().Id;
                //  Console.WriteLine("curHandel:" + handel);
                for (uint j = 0; j < count; j++)
                {
                    //   Console.WriteLine("j:"+j);
                    var i = j;
                    SendMessage(hTrayWnd, TB_GETBUTTON, i, address); //取得TBBUTTON结构到本地
                    int iTmp = 0;
                    var isTrue = ReadProcessMemory(hProcess,
                        address,
                        out btnData,
                        Marshal.SizeOf(btnData),
                        out iTmp);
                    if (isTrue == false) continue;
                    //这一步至关重要，不能省略
                    //主要解决64位系统电脑运行的是x86的程序
                    if (btnData.dwData == IntPtr.Zero)
                    {
                        btnData.dwData = btnData.iString;
                    }
                    ReadProcessMemory(hProcess, //从目标进程address处存放的是TBBUTTON
                        btnData.dwData, //取dwData字段指向的TRAYDATA结构
                        out trayData,
                        Marshal.SizeOf(trayData),
                        out iTmp);

                    UInt32 dwProcessId = 0;
                    GetWindowThreadProcessId(trayData.hwnd, //通过TRAYDATA里的hwnd字段取得本图标的进程id
                        out dwProcessId);
                    //获取当前进程id
                    //  StringBuilder sb = new StringBuilder(256);
                    //  GetModuleFileNameEx(OpenProcess(ProcessAccess.AllAccess, false, dwProcessId), IntPtr.Zero, sb, 256);
                    //  Console.WriteLine(sb.ToString());
                    if (dwProcessId == (UInt32) handel)
                    {

                        Rect rect = new Rect();
                        IntPtr lngRect = VirtualAllocEx(hProcess, //在目标进程中申请一块内存，放TBBUTTON信息
                            IntPtr.Zero,
                            Marshal.SizeOf(typeof (Rect)),
                            AllocationType.Commit,
                            MemoryProtection.ReadWrite);
                        i = j;
                        SendMessage(hTrayWnd, TB_GETITEMRECT, i, lngRect);
                        isTrue = ReadProcessMemory(hProcess, lngRect, out rect, Marshal.SizeOf(rect), out iTmp);

                        //释放内存
                        VirtualFreeEx(hProcess, lngRect, Marshal.SizeOf(rect), FreeType.Decommit);
                        VirtualFreeEx(hProcess, lngRect, 0, FreeType.Release);

                        int left = rectTray.Left + rect.Left;
                        int top = rectTray.Top + rect.Top;
                        int botton = rectTray.Top + rect.Bottom;
                        int right = rectTray.Left + rect.Right;
                        rectNotify = new Rect();
                        rectNotify.Left = left;
                        rectNotify.Right = right;
                        rectNotify.Top = top;
                        rectNotify.Bottom = botton;
                        isFind = true;
                        break;
                    } 
                }
                VirtualFreeEx(hProcess, address, 0x4096, FreeType.Decommit);
                VirtualFreeEx(hProcess, address, 0, FreeType.Release);
                CloseHandle(hProcess);
            }
            return isFind;
        }

7.如果没有找到，那么需要用相同的方法在托盘溢出区域内查找

   private IntPtr FindTrayToolbarOverFlowWindow()
        {
            IntPtr hWnd = FindWindow("NotifyIconOverflowWindow", null);
            if (hWnd != IntPtr.Zero)
            {
                hWnd = FindWindowEx(hWnd, IntPtr.Zero, "ToolbarWindow32", null);
            }
            return hWnd;
        }

在查找中的难点：

1.对于32位操作系统和64位操作系统，系统内部处理方式不一样，所以许多时候当去取TBBUTTON结构到本地的时候得到的地址为0，这里查询了一些资料，网上一些资料TBBUTTON的结构体如下：

  [StructLayout(LayoutKind.Sequential, Pack = 1)]
        public struct TBBUTTON
        {
            public int iBitmap;
            public int idCommand;
            public byte fsState;
            public byte fsStyle;
            public byte bReserved0;
            public byte bReserved1;
            public IntPtr dwData;
            public IntPtr iString;
        }

这个在32位下面没有问题，但是在64位系统下就出现了问题，后面参考网上一些资料，原来问题出在中间4个byte中，由于32位系统中4个byte刚好32位，但是在64位中这里就不对，所以就修改为如下：

[StructLayout(LayoutKind.Sequential, Pack = 1)]
        public struct TBBUTTON
        {
            public int iBitmap;
            public int idCommand;
            public IntPtr fsStateStylePadding;
            public IntPtr dwData;
            public IntPtr iString;
        }

修改过后在64位系统中运行通过了，在这样一位问题解决了，但是当我将解决方案迁移到程序当中的时候，却出了问题，一直不能得到地址，查找了很多原因，原来是在我程序编译的时候，生成的平台是X86，那么就造成了64位系统中使用32位平台时出现问题：

到这里我就猜想是不是 public IntPtr fsStateStylePadding;这一句出了问题，当时x86平台的时候，这个只占用了32位，但是实际64位系统这个位置应该要占用64位，造成地址不对，出错了。

那么接下来我就证实了下这个问题，在我获取地址的时候在public IntPtr dwData;字段中没有获取到，但是在public IntPtr iString;字段中获取到了，那么证明我的猜想是对的（真正是否正确还需要指正），

那么解决方案就来了，为了更好的兼容性，结构体不变，当获取dwData地址没有获取到的时候，我们查找iString字段就好了，方法在这里：

//这一步至关重要，不能省略
                    //主要解决64位系统电脑运行的是x86的程序
                    if (btnData.dwData == IntPtr.Zero)
                    {
                        btnData.dwData = btnData.iString;
                    }

把这个主要的解决了，后面就是查找当前托盘图标相对于父窗体的位置了，使用了很多方法：

GetWindowRect

ScreenToClient

GetClientRect

这些方法都没有成功，最后发现网上有这么一种方法。

 SendMessage(hTrayWnd, TB_GETITEMRECT, i, lngRect);
                        isTrue = ReadProcessMemory(hProcess, lngRect, out rect, Marshal.SizeOf(rect), out iTmp);

在这里真正感受到c++的强大。

在解决这个问题的过程中，参考了很多方案，通过整合才解决了这个问题，如下：

以下是调用方法：

        {
            this._notifyIcon.MouseDoubleClick += notifyIcon_MouseDoubleClick;
            _notifyIcon.MouseMove += new MouseEventHandler(notifyIcon_MouseMove);
            CreateNotifyMouseHelper();
        }

 private NotifyIconMouseHelper notifyHelper;
        private Timer timer = null;
 private void CreateNotifyMouseHelper()
        {
            notifyHelper=new NotifyIconMouseHelper();
            notifyHelper.MouseEnterNotifyStatusChanged+= MouseEnterNotifyStatusChanged;
        }
 private void MouseEnterNotifyStatusChanged(object sender, bool isEnter)
        {
           
            if (isEnter)
            {
              Console.WriteLine("鼠标进入");
            }
            else
            {
              Console.WriteLine("鼠标离开");
