使用SendInput C#模拟键盘 [英] Simulating Keyboard with SendInput C#

问题描述

我尝试使用以下代码从直接X游戏的键盘上模拟一个按键:

I tried to simulate a key from the keyboard for a direct x game with this code:

public static void Send(short Keycode)
{
    INPUT[] InputData = new INPUT[1];

    InputData[0].type = 1;
    InputData[0].ki.wScan = Keycode;
    InputData[0].ki.dwFlags = KEYEVENTF_KEYUP | KEYEVENTF_SCANCODE;
    InputData[0].ki.time = 0;
    InputData[0].ki.dwExtraInfo = IntPtr.Zero;

    SendInput(1, InputData, Marshal.SizeOf(typeof(INPUT)));
}

问题是，这不能模拟密钥.没有按下键.

The problem is, this does not simulate the key. The key isn't pressed.

推荐答案

您需要先发送一个KEYEVENTF_KEYDOWN事件，然后发送一个KEYEVENTF_KEYUP事件，以便游戏正确处理关键事件.

You need to send a KEYEVENTF_KEYDOWN and then a KEYEVENTF_KEYUP event in order for the game to correctly process the key events.

在发送关键事件之间留一点停顿.

Leave a little pause in between the sending of the key events.

如果游戏正在轮询按键，然后有时间识别被按下的按键，则需要这样做.

This is needed if the game is polling the keys, it then has time to recognize the pressed key.
