c# - 如何使用 keybd_event 模拟 Ctrl A + Ctrl C

Question

如何模拟 Ctrl-A + Ctrl-C 使用 keybd_event?

因为我在网络浏览器表单上模拟 ctrl a + ctrl c 来复制剪贴板上的全部内容。我使用了 SendKeys.SendWait 但它没有复制全部内容!

这应该可行

[DllImport("user32.dll", SetLastError = true)]
static extern void keybd_event(byte bVk, byte bScan, int dwFlags, int dwExtraInfo);

public const int KEYEVENTF_KEYDOWN = 0x0000; // New definition
public const int KEYEVENTF_EXTENDEDKEY = 0x0001; //Key down flag
public const int KEYEVENTF_KEYUP = 0x0002; //Key up flag
public const int VK_LCONTROL = 0xA2; //Left Control key code
public const int A = 0x41; //A key code
public const int C = 0x43; //C key code

public static void PressKeys()
{
    // Hold Control down and press A
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(A, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(A, 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);

    // Hold Control down and press C
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(C, 0, KEYEVENTF_KEYDOWN, 0);
    keybd_event(C, 0, KEYEVENTF_KEYUP, 0);
    keybd_event(VK_LCONTROL, 0, KEYEVENTF_KEYUP, 0);
}
