1、今天在網(wǎng)上看到有人問(wèn)C#如何實(shí)現(xiàn)鼠標(biāo)左鍵自動(dòng)點(diǎn)擊并自己設(shè)定點(diǎn)擊間隔，我也感到很好奇，查了一下發(fā)現(xiàn)很簡(jiǎn)單，只需利用WIN32 API的兩個(gè)函數(shù)SetCursorPos和mouse_event操作鼠標(biāo)：調(diào)用方法如下：DllImport("user32.dll")           static extern bool SetCursorPos(int X, int Y);   DllImport("user32.dll") &#

2、160;         static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);           Flags           enum MouseEventFlag : uint  

3、60;                     Move = 0x0001,               LeftDown = 0x0002,             &

4、#160; LeftUp = 0x0004,               RightDown = 0x0008,               RightUp = 0x0010,               Mi

5、ddleDown = 0x0020,               MiddleUp = 0x0040,               XDown = 0x0080,               XUp = 0x0

6、100,               Wheel = 0x0800,               VirtualDesk = 0x4000,               Absolute = 0x8000

7、60;           其中SetCursorPos使鼠標(biāo)移動(dòng)到指定位置；mouse_event使用MouseEventFlag枚舉中的Move，也可以使鼠標(biāo)移動(dòng)。mouse_event中使用不同的枚舉值可以模擬不同的鼠標(biāo)事件。值得注意的是有幾點(diǎn)：1. 我們不能用mouse_event(MouseEventFlag.LeftDown, 10, 10, 0, UIntPtr.Zero);去模擬在(10, 10)處的左鍵事件，我們需要把這步拆成兩步：第一步：移動(dòng)鼠標(biāo)到(10,10)處，用SetCursor

8、Pos(10, 10);第二步：觸發(fā)左鍵，用mouse_event(MouseEventFlag.LeftDown, 0, 0, 0, UIntPtr.Zero);本質(zhì)上是兩步的事件，不能把window API 想的太聰明，認(rèn)為它會(huì)自動(dòng)跑到(10,10)處，再左鍵2. MouseEventFlag的枚舉值可以多個(gè)一起用，使用 | 操作符鼠標(biāo)左鍵按下和松開(kāi)兩個(gè)事件的組合即一次單擊： mouse_event (MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 ) 兩次連續(xù)的鼠標(biāo)左鍵單擊事件 構(gòu)成一次鼠標(biāo)雙擊事件： mouse_event (

9、MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 )mouse_event (MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, 0, 0, 0, 0 ) 3. MouseEventFlag中有個(gè)Absolute枚舉，如果沒(méi)指定Absolute， 則mouse_event的操作是相對(duì)于上次鼠標(biāo)所在的位置；如果指定了Absolute，則是相對(duì)于整個(gè)屏幕坐標(biāo)的位置。這里要注意，指定Absolute，鼠標(biāo)的坐標(biāo)會(huì)被約束在0, 65535之間。0即對(duì)應(yīng)屏幕左，65535即對(duì)應(yīng)屏幕右下角。所以模擬在(1

10、0, 10)處的左鍵，代碼應(yīng)改為： 知道了這些之后，事情就變得相當(dāng)簡(jiǎn)單了，可以建一個(gè)線程來(lái)控制鼠標(biāo)的事件。完整代碼如下：namespace ControlMouse    public partial class Form1 : Form            DllImport("User32")        public extern static void m

11、ouse_event(int dwFlags, int dx, int dy, int dwData, IntPtr dwExtraInfo);        DllImport("User32")        public extern static void SetCursorPos(int x, int y);        DllImport("U

12、ser32")        public extern static bool GetCursorPos(out POINT p);        StructLayout(LayoutKind.Sequential)        public struct POINT         

13、0;          public int X;            public int Y;                        public enum MouseEven

14、tFlags                    Move = 0x0001,            LeftDown = 0x0002,            LeftUp = 0x0004,&#

15、160;           RightDown = 0x0008,            RightUp = 0x0010,            MiddleDown = 0x0020,       

16、60;    MiddleUp = 0x0040,            Wheel = 0x0800,            Absolute = 0x8000                /在(x,y)處

17、單擊        private void AutoClick(int x, int y)                    POINT p = new POINT();            GetCursorPos(out p);

18、            try                            SetCursorPos(x, y);         

19、;       mouse_event(int)(MouseEventFlags.LeftDown | MouseEventFlags.Absolute), 0, 0, 0, IntPtr.Zero);                mouse_event(int)(MouseEventFlags.LeftUp | MouseEventFlags.Absolute), 0, 0, 0,

20、IntPtr.Zero);                        finally                         &

21、#160;  SetCursorPos(p.X, p.Y);                            Point CursorPosition = new Point(0, 0);             

22、   Thread controlThread; /控制鼠標(biāo)的線程        private void ThreadRunMethod()                    while (true)          &#

23、160;                 CursorPosition = Cursor.Position;                Thread.Sleep(5000);   /時(shí)間間隔       &

24、#160;        AutoClick(CursorPosition.X, CursorPosition.Y);                               Thread.Sleep(5000);  

25、;              AutoClick(CursorPosition.X + 2, CursorPosition.Y - 15);                           

26、60;                                public Form1()                    InitializeComponent();                private void button1_Click(object sender, EventArgs e)                    try
