下面我通过代码为大家分享下C#模拟鼠标,具体内容如下:
想必有很多人在项目开发中可能遇见需要做模拟鼠标点击的小功能,很多人会在百度过后采用mouse_event这个函数,不过我并不想讨论如何去使用mouse_event函数怎么去使用,因为那没有多大意义。
- static void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo)
- {
- int x = dx, y = dy;
- edit_position(dwFlags, dx, dy, ref x, ref y);
- IntPtr hWndFromPoint = WindowFromPoint(x, y);
- screen_to_client(hWndFromPoint, ref x, ref y);
- send_message(hWndFromPoint, dwFlags, cButtons, x, y);
- }
上述代码你发现了什么?如果你发现说明你知道了本文到底在写什么东东 说不定你会有一些兴趣看下去,不过想到我如今混那么凄惨 在工地上做干活 不过也还好。
鼠标点击目标时会向鼠标所点击目标窗口投递消息,根据鼠标的按键、状态不同会投递不同的消息,一个完整的“鼠标左键单击”事件过程为“WM_LBUTTONDOWN +
WM_LBUTTONUP”即鼠标“先左键按下 + 后左键抬起”,由于mouse_event可以模拟鼠标点击过程而不是直接性一次完整的鼠标单击过程,所以同样存在“按下、抬起”
mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP | MOUSEEVENTF_MOVE, -450, 0, 1, 0);
mouse_event在没有提供MOUSEEVENTF_MOVE量时光标不会移动到相对位置,“光标相对位置=光标现行位置+新光标位置”如果提供量“MOUSEEVENTF_ABSOLUTE”绝对位置,则会以“新光标位置”为准而不会添加“光标现行位置”
- static void edit_position(int dwFlags, int dx, int dy, ref int x, ref int y)
- {
- Point pos = MousePosition;
- x = x + pos.X;
- y = y + pos.Y;
- if ((dwFlags | MOUSEEVENTF_ABSOLUTE) == dwFlags)
- SetCursorPos(dx, dy);
- if ((dwFlags | MOUSEEVENTF_MOVE) == dwFlags)
- SetCursorPos(x, y);
- }
edit_position函数主要用于对MOUSEEVENTF_MOVE于MOUSEEVENTF_ABSOLUTE
相对/绝对光标位置修改的一个支持
- static void send_message(IntPtr hWnd, int dwFlags, int cButtons, int x, int y)
- {
- if ((dwFlags | MOUSEEVENTF_LEFTDOWN) == dwFlags)
- SendMessage(hWnd, WM_LBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_LEFTUP) == dwFlags)
- SendMessage(hWnd, WM_LBUTTONUP, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_RIGHTDOWN) == dwFlags)
- SendMessage(hWnd, WM_RBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_RIGHTUP) == dwFlags)
- SendMessage(hWnd, WM_RBUTTONUP, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_MIDDLEDOWN) == dwFlags)
- SendMessage(hWnd, WM_MBUTTONDOWN, cButtons, MakeDWord(x, y));
- if ((dwFlags | MOUSEEVENTF_MIDDLEUP) == dwFlags)
- SendMessage(hWnd, WM_MBUTTONUP, cButtons, MakeDWord(x, y));
- }
send_message函数主要用于模拟鼠标点击的过程,上面我提到“先左键按下 + 后左键抬起”在上面的代码中你会看的清楚的不得了,如果相反你可以去尝试一番会有什么后果与其说
不如你们自己做更要来的快些。
- static int MakeDWord(int low, int high)
- {
- return low + (high * Abs(~ushort.MaxValue));
- }
- static int Abs(int value)
- {
- return ((value >> 31) ^ value) - (value >> 31);
- }
- MakeDWord / 合并整数,函数主要是把两个short合并为一个int,分为low、high两部分
- static bool screen_to_client(IntPtr hwnd, ref int x, ref int y)
- {
- bool bRetVal = false;
- Point lpptPos = new Point(x, y);
- if ((bRetVal = ScreenToClient(hwnd, ref lpptPos)))
- {
- x = lpptPos.X;
- y = lpptPos.Y;
- }
- return bRetVal;
- }
- screen_to_client函数故名思意,它主要用于把屏幕上的坐标转换到窗口客户上对应坐标
- public const int WM_LBUTTONDOWN = 513; // 鼠标左键按下
- public const int WM_LBUTTONUP = 514; // 鼠标左键抬起
- public const int WM_RBUTTONDOWN = 516; // 鼠标右键按下
- public const int WM_RBUTTONUP = 517; // 鼠标右键抬起
- public const int WM_MBUTTONDOWN = 519; // 鼠标中键按下
- public const int WM_MBUTTONUP = 520; // 鼠标中键抬起
- public const int MOUSEEVENTF_MOVE = 0x0001; // 移动鼠标
- public const int MOUSEEVENTF_LEFTDOWN = 0x0002; // 鼠标左键按下
- public const int MOUSEEVENTF_LEFTUP = 0x0004; // 鼠标左键抬起
- public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; // 鼠标右键按下
- public const int MOUSEEVENTF_RIGHTUP = 0x0010; // 鼠标右键抬起
- public const int MOUSEEVENTF_MIDDLEDOWN = 0x0020; // 鼠标中键按下
- public const int MOUSEEVENTF_MIDDLEUP = 0x0040; // 鼠标中键抬起
- public const int MOUSEEVENTF_ABSOLUTE = 0x8000; // 绝对坐标
