static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);

MouseEventFlag表示鼠標(biāo)事件的類型，可取多個(gè)枚舉值組合。注意dx,dy參數(shù)，必須是絕對(duì)坐標(biāo)（0,0）~（65535,65535）中的一點(diǎn)。

/// <summary>
/// 鼠標(biāo)操作標(biāo)志位集合
/// </summary>
[Flags]
enum MouseEventFlag : uint
{
/// <summary>
/// 鼠標(biāo)移動(dòng)事件
/// </summary>
Move = 0x0001,

/// <summary>
/// 鼠標(biāo)左鍵按下事件
/// </summary>
LeftDown = 0x0002,
LeftUp = 0x0004,
RightDown = 0x0008,
RightUp = 0x0010,
MiddleDown = 0x0020,
MiddleUp = 0x0040,
XDown = 0x0080,
XUp = 0x0100,
Wheel = 0x0800,
VirtualDesk = 0x4000,
/// <summary>
/// 設(shè)置鼠標(biāo)坐標(biāo)為絕對(duì)位置（dx,dy）,否則為距離最后一次事件觸發(fā)的相對(duì)位置
/// </summary>
Absolute = 0x8000
}

2.調(diào)用mouse_event函數(shù)，觸發(fā)鼠標(biāo)事件

/// <summary>
/// 觸發(fā)鼠標(biāo)事件
/// </summary>
/// <param name="x"></param>
/// <param name="y"></param>
private static void DoMouseClick(int x, int y)
{
  int dx = (int)((double)x / Screen.PrimaryScreen.Bounds.Width * 65535); //屏幕分辨率映射到0~65535(0xffff,即16位)之間
  int dy = (int)((double)y / Screen.PrimaryScreen.Bounds.Height * 0xffff); //轉(zhuǎn)換為double類型運(yùn)算，否則值為0、1
  mouse_event(MouseEventFlag.Move | MouseEventFlag.LeftDown | MouseEventFlag.LeftUp | MouseEventFlag.Absolute, dx, dy, 0, new UIntPtr(0)); //點(diǎn)擊
}

二、鍵盤事件的觸發(fā)

1.引用windows函數(shù)keybd_event

/// <summary>
/// 鍵盤事件
/// </summary>
/// <param name="bVk"> virtual-key code</param>
/// <param name="bScan">hardware scan code</param>
/// <param name="dwFlags"> flags specifying various function options</param>
/// <param name="dwExtraInfo"> additional data associated with keystroke</param>
[DllImport("user32.dll")]
public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

bvk為鍵值，例如回車13，bScan設(shè)置為0，dwFlags設(shè)置0表示按下，2表示抬起；dwExtraInfo也設(shè)置為0即可。

2.調(diào)用keybd_event函數(shù)，觸發(fā)鍵盤事件

下面的代碼演示觸發(fā)Ctrl+C組合鍵，執(zhí)行復(fù)制操作。

keybd_event((byte)Keys.ControlKey, 0, 0, 0);
keybd_event((byte)Keys.C, 0, 0, 0);
keybd_event((byte)Keys.ControlKey, 0, 2, 0);
keybd_event((byte)Keys.C, 0, 2, 0);

希望本文所述實(shí)例對(duì)大家的C#程序設(shè)計(jì)能起到一定的幫助作用。
