下面我通過代碼為大家分享下C#模擬鼠標，具體內容如下：

想必有很多人在項目開發(fā)中可能遇見需要做模擬鼠標點擊的小功能，很多人會在百度過后采用mouse_event這個函數(shù)，不過我并不想討論如何去使用mouse_event函數(shù)怎么去使用，因為那沒有多大意義。

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); }

上述代碼你發(fā)現(xiàn)了什么？如果你發(fā)現(xiàn)說明你知道了本文到底在寫什么東東說不定你會有一些興趣看下去，不過想到我如今混那么凄慘在工地上做干活不過也還好。

鼠標點擊目標時會向鼠標所點擊目標窗口投遞消息，根據(jù)鼠標的按鍵、狀態(tài)不同會投遞不同的消息，一個完整的“鼠標左鍵單擊”事件過程為“WM_LBUTTONDOWN +

WM_LBUTTONUP”即鼠標“先左鍵按下 + 后左鍵抬起”，由于mouse_event可以模擬鼠標點擊過程而不是直接性一次完整的鼠標單擊過程，所以同樣存在“按下、抬起”

mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP | MOUSEEVENTF_MOVE, -450, 0, 1, 0);
mouse_event在沒有提供MOUSEEVENTF_MOVE量時光標不會移動到相對位置，“光標相對位置=光標現(xiàn)行位置+新光標位置”如果提供量“MOUSEEVENTF_ABSOLUTE”絕對位置，則會以“新光標位置”為準而不會添加“光標現(xiàn)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函數(shù)主要用于對MOUSEEVENTF_MOVE于MOUSEEVENTF_ABSOLUTE

相對/絕對光標位置修改的一個支持

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函數(shù)主要用于模擬鼠標點擊的過程，上面我提到“先左鍵按下 + 后左鍵抬起”在上面的代碼中你會看的清楚的不得了，如果相反你可以去嘗試一番會有什么后果與其說

不如你們自己做更要來的快些。

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 / 合并整數(shù)，函數(shù)主要是把兩個short合并為一個int，分為low、high兩部分  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函數(shù)故名思意，它主要用于把屏幕上的坐標轉換到窗口客戶上對應坐標 public const int WM_LBUTTONDOWN = 513; // 鼠標左鍵按下 public const int WM_LBUTTONUP = 514; // 鼠標左鍵抬起 public const int WM_RBUTTONDOWN = 516; // 鼠標右鍵按下 public const int WM_RBUTTONUP = 517; // 鼠標右鍵抬起 public const int WM_MBUTTONDOWN = 519; // 鼠標中鍵按下 public const int WM_MBUTTONUP = 520; // 鼠標中鍵抬起 public const int MOUSEEVENTF_MOVE = 0x0001; // 移動鼠標   public const int MOUSEEVENTF_LEFTDOWN = 0x0002; // 鼠標左鍵按下  public const int MOUSEEVENTF_LEFTUP = 0x0004; // 鼠標左鍵抬起  public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; // 鼠標右鍵按下  public const int MOUSEEVENTF_RIGHTUP = 0x0010; // 鼠標右鍵抬起   public const int MOUSEEVENTF_MIDDLEDOWN = 0x0020; // 鼠標中鍵按下 public const int MOUSEEVENTF_MIDDLEUP = 0x0040; // 鼠標中鍵抬起   public const int MOUSEEVENTF_ABSOLUTE = 0x8000; // 絕對坐標 [DllImport("user32.dll", SetLastError = true)] public static extern int SendMessage(IntPtr hWnd, int uMsg, int wParam, int lParam); [DllImport("user32.dll", SetLastError = true)] public static extern IntPtr WindowFromPoint(int xPoint, int yPoint); [DllImport("user32.dll", SetLastError = true)] public static extern int SetCursorPos(int x, int y); [DllImport("user32.dll", SetLastError = true)] public static extern bool ScreenToClient(IntPtr hWnd, ref Point lppt); // [DllImport("user32", SetLastError = true)] // public static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

鼠標右鍵單擊(靜默)：

復制代碼代碼如下:

mouse_event(MOUSEEVENTF_RIGHTDOWN | MOUSEEVENTF_RIGHTUP, 0, 0, 1, 0);

鼠標左鍵雙擊(靜默):

復制代碼代碼如下:

mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 2, 0);

鼠標移動(相對位置):

復制代碼代碼如下:

mouse_event(MOUSEEVENTF_MOVE, 100, 50, 0, 0);

鼠標移動(絕對位置):

復制代碼代碼如下:

mouse_event(MOUSEEVENTF_ABSOLUTE, 100, 50, 0, 0);
