上面我經由過程代碼為年夜家分享下C#模仿鼠標，詳細內容以下：

想必有許多人在項目開辟中能夠碰見須要做模仿鼠標點擊的小功效，許多人會在百渡過後采取mouse_event這個函數，不外我其實不想評論辯論若何去應用mouse_event函數怎樣去應用，由於那沒有多年夜意義。

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); 
} 

 
上述代碼你發明了甚麼？假如你發明解釋你曉得了本文究竟在寫甚麼東東 說不定你會有一些興致看下去，不外想到我現在混那末悲涼 在工地上做干活 不外也還好。

鼠標點擊目的時會向鼠標所點擊目的窗口送達新聞，依據鼠標的按鍵、狀況分歧會送達分歧的新聞，一個完全的“鼠標左鍵單擊”事宜進程為“WM_LBUTTONDOWN +

WM_LBUTTONUP”即鼠標“先左鍵按下 + 後左鍵抬起”，因為mouse_event可以模仿鼠標點擊進程而不是直接性一次完全的鼠標單擊進程，所以異樣存在“按下、抬起”

mouse_event(MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP | MOUSEEVENTF_MOVE, -450, 0, 1, 0); 
mouse_event在沒有供給MOUSEEVENTF_MOVE量時間標不會挪動到絕對地位，“光標絕對地位=光標現行地位+新光標地位”假如供給量“MOUSEEVENTF_ABSOLUTE”相對地位，則會以“新光標地位”為准而不會添加“光標現行地位”

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函數重要用於對MOUSEEVENTF_MOVE於MOUSEEVENTF_ABSOLUTE

絕對/相對光標地位修正的一個支撐

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函數重要用於模仿鼠標點擊的進程，下面我提到“先左鍵按下 + 後左鍵抬起”在下面的代碼中你會看的清晰的不得了，假如相反你可以去測驗考試一番會有甚麼效果與其說

不如你們本身做更要來的快些。

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 / 歸並整數，函數重要是把兩個short歸並為一個int，分為low、high兩部門
 
 
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函數故名思意，它重要用於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; // 挪動鼠標   
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; // 相對坐標

鼠標右鍵單擊(靜默)：

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

鼠標左鍵雙擊(靜默):

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

鼠標挪動(絕對地位):

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

鼠標挪動(相對地位):

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