C#/Powershell 发送组合键

Question

我发现这个函数使用 C# 代码通过 PowerShell 模拟按键。

我可以像这样模拟一个 WINDOWS 键：

[KBEmulator]::SendScanCode(0x5B)

但是我想发送组合 WINDOWS+CTRL+SHIFT+B

其中，就 ScanCode 而言是：

0x5B + 0x11 + 0x10 + 0x42

不幸的是，我只精通 PowerShell 而对 C# 一无所知。

有没有一种方法可以修改此代码以使用组合键而不是一次只使用一个键？

功能按键：

Function KeyPress {

Param (
    [Parameter(position=0, mandatory=$true, parametersetname='key')]
    [char]$Key,
    [Parameter(position=0, mandatory=$true, parametersetname='scancode')]
    [int]$ScanCode
)

这是我的尝试，至少应该是一个开始的地方。有一段时间没有在 C# 中编写任何代码，所以不确定如何在其中进行编程，但希望它应该接受字符数组并按下数组中的键并作为数组结构发送。 for 循环可能是索引关闭，但不确定，并且可能存在我在代码中没有意识到的随机错误，我什至不确定它是否会同时按下所有按键或一次按下一个按键，但希望这可以帮助您了解从哪里开始。

public static void SendKeyboard(char ch) {
    lpInput[] KeyInputs = new lpInput[1];
    lpInput KeyInput = new lpInput();
    // Generic Keyboard Event
    KeyInput.type = InputType.INPUT_KEYBOARD;
    KeyInput.Data.ki.wScan = 0;
    KeyInput.Data.ki.time = 0;
    KeyInput.Data.ki.dwExtraInfo = UIntPtr.Zero;


    // Push the correct key
    KeyInput.Data.ki.wVk = VkKeyScan(ch);
    KeyInput.Data.ki.dwFlags = KEYEVENTF.KEYDOWN;
    KeyInputs[0] = KeyInput;
    SendInput(1, KeyInputs, lpInput.Size);

    // Release the key
    KeyInput.Data.ki.dwFlags = KEYEVENTF.KEYUP;
    KeyInputs[0] = KeyInput;
    SendInput(1, KeyInputs, lpInput.Size);

    return;  
    }

 // Attempt at overloading for multiple key presses
 public static void SendKeyboard(char[] ch) {
    lpInput[] KeyInputs = new lpInput[ch.length];

    // Push the correct key
    for (int i = 0; i < ch.length; i++) {
    // Generate new memory address for KeyInput each time
    lpInput KeyInput = new lpInput();
    // Generic Keyboard Event
    KeyInput.type = InputType.INPUT_KEYBOARD;
    KeyInput.Data.ki.wScan = 0;
    KeyInput.Data.ki.time = 0;
    KeyInput.Data.ki.dwExtraInfo = UIntPtr.Zero;
    KeyInput.Data.ki.wVk = VkKeyScan(ch[i]);
    KeyInput.Data.ki.dwFlags = KEYEVENTF.KEYDOWN;
    KeyInputs[i] = KeyInput;
    }
    SendInput( ch.length, KeyInputs, ( lpInput.Size * ch.length ) );

    // Release the key
    for (int i = 0; i < ch.length; i++) {
    // Generate new memory address for KeyInput each time
    lpInput KeyInput = new lpInput();
    // Generic Keyboard Event
    KeyInput.type = InputType.INPUT_KEYBOARD;
    KeyInput.Data.ki.wScan = 0;
    KeyInput.Data.ki.time = 0;
    KeyInput.Data.ki.dwExtraInfo = UIntPtr.Zero;
    KeyInput.Data.ki.wVk = VkKeyScan(ch[i]);
    KeyInput.Data.ki.dwFlags = KEYEVENTF.KEYUP;
    KeyInputs[i] = KeyInput;
    }
    SendInput(ch.length, KeyInputs, ( lpInput.Size * ch.length ) );

    return;  
    }
