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。

鼠标右键单击(静默):
鼠标左键双击(静默):
鼠标移动(相对位置):
鼠标移动(绝对位置):
以上内容比较多请认真学习,希望能够帮助到大家。
