在 C# 中模拟键盘输入

【中文标题】在 C# 中模拟键盘输入【英文标题】：Simulate keyboard input in C# 【发布时间】：2013-12-27 06:05:32 【问题描述】：我需要知道如何模拟键 W、S、A、D 的键盘输入。
我使用了SendKeys 无济于事，也使用了InputSimulator 库但没有修复。
我想要做的是让游戏（战地、自然选择等较新的 FPS 游戏）等应用程序将这些模拟键注册为真正的击键。我正在尝试制作一个虚拟控制器程序，其中外部控件将注册为这些游戏的键盘输入。
有没有办法像这样手动模拟键盘输入？
[DllImport("user32.dll",
CharSet = CharSet.Auto,
CallingConvention = CallingConvention.StdCall)]
public static extern void mouse_event(uint dwFlags,
uint dx,
uint dy,
int cButtons,
uint dwExtraInfo);
【问题讨论】：
显示您使用的发送密钥语法 您到底为什么要使用 mouse_event 模拟键盘输入？ 我不想使用 mouse_event 我说的是类似的东西，它会向计算机发送消息以模拟按下的按钮。我使用的键语法只是 Sendkeys.sendwait("W");这在游戏中不起作用。 【参考方案1】：您是否尝试过使用取代keybd_event 的SendInput？
要从 C# 调用 SendInput，您将需要创建一大堆结构。幸运的是，大部分信息都可以从pinvoke.net 收集到。
查看SendInput 和INPUT 结构的pinvoke 文档，我想到了以下内容。我在顶部编写的名为 SendInputWithAPI 的方法是调用 SendInput 来模拟“wsad”的发送。其余代码只是使其工作所需的结构声明。
void SendInputWithAPI()
INPUT[] Inputs = new INPUT[4];
INPUT Input = new INPUT();
Input.type = 1; // 1 = Keyboard Input
Input.U.ki.wScan = ScanCodeShort.KEY_W;
Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;
Inputs[0] = Input;
Input.type = 1; // 1 = Keyboard Input
Input.U.ki.wScan = ScanCodeShort.KEY_S;
Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;
Inputs[1] = Input;
Input.type = 1; // 1 = Keyboard Input
Input.U.ki.wScan = ScanCodeShort.KEY_A;
Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;
Inputs[2] = Input;
Input.type = 1; // 1 = Keyboard Input
Input.U.ki.wScan = ScanCodeShort.KEY_D;
Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;
Inputs[3] = Input;
SendInput(4, Inputs, INPUT.Size);

【讨论】：
谢谢，我一定要试试这个！看起来很有希望！也感谢您非常详细的回复！而不是仅仅告诉我我需要做什么，你实际上帮助我学会了如何去做！ 太棒了！我有一个简单的问题，您将如何模拟按键向下和向上按键？非常感谢你@Gareth @Gareth：我修好了。我想“按下”一个键，然后在“按下”另一个键之前等待一段时间（1 秒左右）。我使用了多个 SendInput 调用并且它有效。不过，很棒的代码！谢谢！ 太棒了！谢谢。例如，当您想要打印大写字母时，情况如何。所以你需要按住 shift 和 + 字母。如何模拟？ 仅供参考，为避免大量虚拟键/扫描码枚举，只需使用 MapVirtualKeyA (docs.microsoft.com/en-us/windows/win32/api/winuser/…)，这样您就可以使用 WinForms 库中的 Keys 枚举（转换为 uint）将返回相应的扫描码。【参考方案2】：我喜欢@Gareth 的做法。但是，在他的方法中，您需要将击键硬编码到 SendInputWithAPI() 方法中。我对代码做了一些修改；您现在可以调用 Send() 并将 ScanCodeShort 参数传递给它。这使您可以在任何时间、任何地点将任何击键传递给它。

如果您的游戏以管理员身份运行，请不要忘记以管理员身份运行脚本。否则游戏将不会接收输入。 - 花了我 2 个小时来找出答案。 仅供参考，为避免大量虚拟键/扫描码枚举，只需使用 MapVirtualKeyA (docs.microsoft.com/en-us/windows/win32/api/winuser/…)，这样您就可以使用 WinForms 库中的 Keys 枚举（转换为 uint）将返回相应的扫描码。 这个确实搞砸了我电脑上的输入，不管我做了什么尝试修复它都会锁定我的 Shift 键并强制我重新启动。【参考方案3】：除了@gareth 的出色回答之外，要在判刑期间模拟大写字母，您可以在下面使用我的解决方案..
public static void SendWithShift(ScanCodeShort a)
HoldLShift();
Send(a);
ReleaseLShift();
public static void HoldLShift()
var Inputs = new InputStruct[1];
var Input = new InputStruct();
Input.type = 1;
Input.U.ki.wScan = ScanCodeShort.LSHIFT;
Input.U.ki.dwFlags = KeyEventF.SCANCODE;
Inputs[0] = Input;
SendInput(1, Inputs, InputStruct.Size);
public static void ReleaseLShift()
var Inputs = new InputStruct[1];
var Input = new InputStruct();
Input.type = 1;
Input.U.ki.wScan = ScanCodeShort.LSHIFT;
Input.U.ki.dwFlags = KeyEventF.KEYUP | KeyEventF.SCANCODE;
Inputs[0] = Input;
SendInput(1, Inputs, InputStruct.Size);
public static void Send(ScanCodeShort a)
var Inputs = new InputStruct[1];
var Input = new InputStruct();
Input.type = 1;
Input.U.ki.wScan = a;
Input.U.ki.dwFlags = KeyEventF.SCANCODE;
Inputs[0] = Input;
SendInput(1, Inputs, InputStruct.Size);
要发送 shift 并保持，您只需要发送，但要释放 shift，您需要添加 keyup 标志，而不仅仅是设置它。

【参考方案4】：我一直在寻找多媒体按钮按下的仿真，发现您需要使用这些参数（在 @Gareth 代码中）：
Input.U.ki.wVk = VirtualKeyShort.VOLUME_MUTE;
Input.U.ki.dwFlags = KEYEVENTF.UNICODE;
【讨论】：
【参考方案5】：在keybd_event 上添加到@ogggre。我设法有一个工作的 DllImport：
[DllImport("user32.dll")]
internal static extern void keybd_event(
byte bVk,
byte bScan,
uint dwFlags,
uint dwExtraInfo
);
【讨论】：
【参考方案6】：我刚刚创建了一个库来使用 dotnet core 和多平台实现来模拟键盘和鼠标（光标）。
这里是github的链接：https://github.com/lucassklp/Desktop.Robot
【讨论】：
【参考方案7】：keybd_event 应该做的工作：
// Simulate a key press
keybd_event( VK_NUMLOCK,
0x45,
KEYEVENTF_EXTENDEDKEY | 0,
0 );
// Simulate a key release
keybd_event( VK_NUMLOCK,
0x45,
KEYEVENTF_EXTENDEDKEY | KEYEVENTF_KEYUP,
0);

谢谢！我想这正是我要找的！我一定会尽快对其进行测试并回复您！ 实际上我正在寻找可以与 C# 和 .NET 一起使用的东西。如果我使用 C++，我相信这会起作用，但是无论如何你可以给我 C# 参考吗？谢谢！ 我刚试过 [DllImport("user32.dll", SetLastError = true)] static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);无济于事。【参考方案8】：添加到@Gareth 的解决方案，因为在调用Send() 后键卡住了。这是@Matthew Wherry 的ReleaseLShift() 的简化版本，因此它适用于任何键。
public static void ReleaseKey(ScanCodeShort key)
var Inputs = new INPUT[1];
var Input = new INPUT();
Input.type = 1;
Input.U.ki.wScan = key;
Input.U.ki.dwFlags = KEYEVENTF.KEYUP | KEYEVENTF.SCANCODE;
Inputs[0] = Input;
SendInput(1, Inputs, INPUT.Size);
【讨论】：
【参考方案9】：您可以使用SendKeys.Send("<your character/string>");
示例：
SendKeys.Send("ENTER");

SendKeys.Send(string) 在 Windows 10 中的支持有限，并不适用于所有用例。如果有人确实使用了这个答案的内容，请注意它可能无法正常工作的可能性非零。【参考方案10】：
Windows 输入模拟器让这变得超级简单。
Windows 输入模拟器提供了一个简单的 .NET (C#) 接口，用于使用 Win32 SendInput 方法模拟键盘或鼠标输入。所有的互操作都是为您完成的，并且有一个用于发送多个击键的简单编程模型。 Nuget 包 -> 安装包 InputSimulator

张贴duplicate answers 是不受欢迎的。特别是这些答案看起来更像是广告文案而不是编程答案，这也使它们看起来像是垃圾邮件。如果无法针对特定问题量身定制答案，则简单的评论将是更好的选择。 感谢您尝试帮助其他用户。感谢您的努力。以上是关于在 C# 中模拟键盘输入的主要内容，如果未能解决你的问题，请参考以下文章
