C# WPF 中用代码模拟鼠标和键盘的操作

C#开发者都知道,在Winform开发中,SendKeys类提供的方法是很实用的。但是可惜的是,在WPF中不能使用这个方法了。
我们知道,在WPF中非UI线程刷新UI线程,需要使用Dispatcher.Invoke((Action)delegate { /* Your
code is put here */ });
方法。这里调用System.Windows.Forms.SendKeys.Send()方法会报错。

下面这个代码文件做了一个很好的包装,可以下载后参考:
Simulation.zip

如何使用呢?
很简单, 要敲一个键, 比如回车:
Keyboard.Press(Key.Enter);
Keyboard.Release(Key.Enter);

要敲一个组合键:比如Alt+F4:
Keyboard.Press(Key.LeftAlt);
Keyboard.Press(Key.F4);
Keyboard.Release(Key.LeftAlt);
Keyboard.Release(Key.F4);

要敲一段文字:
Keyboard.Type(“notepad”);

鼠标与之类似,比如:
Mouse.MoveTo(new System.Drawing.Point(x, y));
Mouse.Click(MouseButton.Right);


Simulation类的定义如下:

//定义是这样的:[DllImport("user32.dll", SetLastError = true)]internal static extern int SendInput(int nInputs, ref INPUT mi, int cbSize);//其中的INPUT结构表示一个键盘或鼠标操作:[StructLayout(LayoutKind.Sequential)]internal struct INPUT{internal int type;internal INPUTUNION union;};[StructLayout(LayoutKind.Explicit)]internal struct INPUTUNION{[FieldOffset(0)]internal MOUSEINPUT mouseInput;[FieldOffset(0)]internal KEYBDINPUT keyboardInput;};[StructLayout(LayoutKind.Sequential)]internal struct MOUSEINPUT{internal int dx;internal int dy;internal int mouseData;internal int dwFlags;internal int time;internal IntPtr dwExtraInfo;};[StructLayout(LayoutKind.Sequential)]internal struct KEYBDINPUT{internal short wVk;internal short wScan;internal int dwFlags;internal int time;internal IntPtr dwExtraInfo;};[Flags]internal enum SendMouseInputFlags{Move = 0x0001,LeftDown = 0x0002,LeftUp = 0x0004,RightDown = 0x0008,RightUp = 0x0010,MiddleDown = 0x0020,MiddleUp = 0x0040,XDown = 0x0080,XUp = 0x0100,Wheel = 0x0800,Absolute = 0x8000,};
