在 C# 中模拟键盘输入 [英] Simulate keyboard input in C#
本文介绍了在 C# 中模拟键盘输入的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要知道如何模拟W、S、A、D 键的键盘输入.
I need to know how to simulate keyboard input for keys W, S, A, D.
我使用了 SendKeys 没有用，InputSimulator 库也没有修复.
I've used SendKeys with no avail as well as the InputSimulator library with no fix.
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按键注册为真实按键.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.
What I'm trying to do is make it to where applications such as games (Battlefield, Natural Selection, ect. Newer FPS games) will register these simulated keys as real keystrokes. I'm trying to make a virtual controller program where external controls will register as keyboard inputs for these games.
有没有办法像这样手动模拟键盘输入?
Is there a way to manually simulate keyboard input like there is with something like this?
[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);
推荐答案
我喜欢 @Gareth 的方法.但是，在他的方法中，您需要将击键硬编码到 SendInputWithAPI() 方法中.我对代码做了一些更改；您现在可以调用 Send() 并将 ScanCodeShort 参数传递给它.这允许您在任何时间、任何地点将任何击键传递给它.
I like @Gareth's approach at it. However, in his method, you need to hard code your key strokes into the SendInputWithAPI() method. I made a few changes to the code; you now can call Send() and pass ScanCodeShort parameter to it. This allows you to pass any keystroke to it, any time, any place.
public class Keyboard
{
public void Send(ScanCodeShort a)
{
INPUT[] Inputs = new INPUT[1];
INPUT Input = new INPUT();
Input.type = 1; // 1 = Keyboard Input
Input.U.ki.wScan = a;
Input.U.ki.dwFlags = KEYEVENTF.SCANCODE;
Inputs[0] = Input;
SendInput(1, Inputs, INPUT.Size);
}
