使用InputSimulator

尝试使用InputSimulator来模拟键盘输入。 一切正常，除了使用sim.Keyboard.ModifiedKeyStroke来模拟ASCII字符的输入。

我尝试使用以下两种不同的方式模拟Alt down + numpad1 + numpad4 + numpad7 + Alt up ：

  sim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LMENU, new[] { VirtualKeyCode.NUMPAD1, VirtualKeyCode.NUMPAD4, VirtualKeyCode.NUMPAD7}); 

和

  sim.Keyboard.KeyDown(VirtualKeyCode.LMENU); sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD1); sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD1); sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD4); sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD4); sim.Keyboard.KeyDown(VirtualKeyCode.NUMPAD7); sim.Keyboard.KeyUp(VirtualKeyCode.NUMPAD7); sim.Keyboard.KeyUp(VirtualKeyCode.LMENU); 

两者都不起作用。 我尝试在控制台中打印出关键状态，真正的按键和模拟按键都给出相同的结果：

  LMenu key down NumPad1 key down NumPad1 key up NumPad4 key down NumPad4 key up NumPad7 key down NumPad7 key up LMenu key up 

我认为应该是图书馆的一些问题： 问题1 。 有人可以帮我这个吗？ 有没有其他方法可以做到这一点？

更新1

我发现“Alt + Tab”在Win8中也不起作用。 我认为这可能是同样的原因所以我试着先解决这个问题。 事实certificate，它们是两个不同的问题：

1. 要使“Alt + Tab”工作，我需要在“app.manifest”中设置uiAccess=true并使用测试数字签名签署“.exe”文件;

2. 模拟ASCII字符的输入仍然无法正常工作。

将keybd_event与MapVirtualKey一起使用，或者如果使用SendInput添加到INPUT的Scan MapVirtualKey 。

这是两个例子，

 using System; using System.Threading; using System.Runtime.InteropServices; namespace kbd_events_example { static class Program { #pragma warning disable 649 internal struct INPUT { public UInt32 Type; public KEYBOARDMOUSEHARDWARE Data; } [StructLayout(LayoutKind.Explicit)] //This is KEYBOARD-MOUSE-HARDWARE union INPUT won't work if you remove MOUSE or HARDWARE internal struct KEYBOARDMOUSEHARDWARE { [FieldOffset(0)] public KEYBDINPUT Keyboard; [FieldOffset(0)] public HARDWAREINPUT Hardware; [FieldOffset(0)] public MOUSEINPUT Mouse; } internal struct KEYBDINPUT { public UInt16 Vk; public UInt16 Scan; public UInt32 Flags; public UInt32 Time; public IntPtr ExtraInfo; } internal struct MOUSEINPUT { public Int32 X; public Int32 Y; public UInt32 MouseData; public UInt32 Flags; public UInt32 Time; public IntPtr ExtraInfo; } internal struct HARDWAREINPUT { public UInt32 Msg; public UInt16 ParamL; public UInt16 ParamH; } #pragma warning restore 649 [DllImport("user32.dll", CharSet = CharSet.Auto, ExactSpelling = true, CallingConvention = CallingConvention.Winapi)] static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, uint extraInfo); [DllImport("user32.dll", SetLastError = true)] static extern int MapVirtualKey(uint uCode, uint uMapType); [DllImport("user32.dll", SetLastError = true)] static extern UInt32 SendInput(UInt32 numberOfInputs, INPUT[] inputs, Int32 sizeOfInputStructure); enum VK { MENU = 0x12, NUMPAD0 = 0x60, NUMPAD1 = 0x61, NUMPAD2 = 0x62, NUMPAD3 = 0x63, NUMPAD4 = 0x64, NUMPAD5 = 0x65, NUMPAD6 = 0x66, NUMPAD7 = 0x67, NUMPAD8 = 0x68, NUMPAD9 = 0x69 } const uint KEYEVENTF_KEYUP = 0x0002; public const int INPUT_KEYBOARD = 1; [STAThread] static void Main() { Thread.Sleep(5000); //wait 5 seconds, so you can focus the Notepad keybd_event((int)VK.MENU, (byte)MapVirtualKey((uint)VK.MENU, 0), 0, 0); //Alt Press keybd_event((int)VK.NUMPAD1, (byte)MapVirtualKey((uint)VK.NUMPAD1, 0), 0, 0); // N1 Press keybd_event((int)VK.NUMPAD1, (byte)MapVirtualKey((uint)VK.NUMPAD1, 0), KEYEVENTF_KEYUP, 0); // N1 Release keybd_event((int)VK.MENU, (byte)MapVirtualKey((uint)VK.MENU, 0), KEYEVENTF_KEYUP, 0); // Alt Release Thread.Sleep(2000); //wait 2 seconds INPUT[] inputs = new INPUT[] { new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.MENU, Flags = 0, Scan = (ushort)MapVirtualKey((uint)VK.MENU, 0), ExtraInfo = IntPtr.Zero, Time = 0}}}, new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.NUMPAD2, Flags = 0, Scan = (ushort)MapVirtualKey((uint)VK.NUMPAD2, 0), ExtraInfo = IntPtr.Zero, Time = 0}}}, new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.NUMPAD2, Flags = 2, Scan = (ushort)MapVirtualKey((uint)VK.NUMPAD2, 0), ExtraInfo = IntPtr.Zero, Time = 0}}}, new INPUT {Type = INPUT_KEYBOARD, Data = new KEYBOARDMOUSEHARDWARE { Keyboard = new KEYBDINPUT { Vk = (ushort)VK.MENU, Flags = 2, Scan = (ushort)MapVirtualKey((uint)VK.MENU, 0), ExtraInfo = IntPtr.Zero, Time = 0}}} }; SendInput((uint)inputs.Length, inputs, Marshal.SizeOf(typeof(INPUT))); } } } 

对于InputSimulator ，您需要使用SendInput或keybd_event编写自己的类，使用MapVirtualKey来处理输入…
