措施触发鼠标、键盘事件是C#措施设计中对照常见的成果，本文实例展示了C#中winform实现自动触发鼠标、键盘事件的要领，有不错的实用价值。具体如下：
要想在C#措施中触发鼠标、键盘事件就必需要挪用windows函数。
一、鼠标事件的触发
1.引用windows函数mouse_event
/// <summary> /// 鼠标事件 /// </summary> /// <param>事件类型</param> /// <param>x坐标值(0~65535)</param> /// <param>y坐标值(0~65535)</param> /// <param>滚动值(120一个单位)</param> /// <param>不撑持</param> [DllImport("user32.dll")] static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);
MouseEventFlag暗示鼠标事件的类型，可取多个枚举值组合。注意dx,dy参数，必需是绝对坐标（0,0）~（65535,65535）中的一点。
/// <summary> /// 鼠标操纵标识表记标帜位调集 /// </summary> [Flags] enum MouseEventFlag : uint { /// <summary> /// 鼠标移动事件 /// </summary> Move = 0x0001, /// <summary> /// 鼠标左键按下事件 /// </summary> LeftDown = 0x0002, LeftUp = 0x0004, RightDown = 0x0008, RightUp = 0x0010, MiddleDown = 0x0020, MiddleUp = 0x0040, XDown = 0x0080, XUp = 0x0100, Wheel = 0x0800, VirtualDesk = 0x4000, /// <summary> /// 设置鼠标坐标为绝对位置（dx,dy）,否则为距离最后一次事件触发的相对位置 /// </summary> Absolute = 0x8000 }
2.挪用mouse_event函数，触发鼠标事件
/// <summary> /// 触发鼠标事件 /// </summary> /// <param></param> /// <param></param> private static void DoMouseClick(int x, int y) { int dx = (int)((double)x / Screen.PrimaryScreen.Bounds.Width * 65535); //屏幕辨别率映射到0~65535(0xffff,即16位)之间 int dy = (int)((double)y / Screen.PrimaryScreen.Bounds.Height * 0xffff); //转换为double类型运算，否则值为0、1 mouse_event(MouseEventFlag.Move | MouseEventFlag.LeftDown | MouseEventFlag.LeftUp | MouseEventFlag.Absolute, dx, dy, 0, new UIntPtr(0)); //点击 }
二、键盘事件的触发
1.引用windows函数keybd_event
/// <summary> /// 键盘事件 /// </summary> /// <param> virtual-key code</param> /// <param>hardware scan code</param> /// <param> flags specifying various function options</param> /// <param> additional data associated with keystroke</param> [DllImport("user32.dll")] public static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);
bvk为键值，，例如回车13，bScan设置为0，dwFlags设置0暗示按下，2暗示抬起；dwExtraInfo也设置为0即可。
2.挪用keybd_event函数，触发键盘事件
下面的代码演示触发Ctrl+C组合键，执行复制操纵。
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);
