Question

This is my code:

void tbHotkey_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
{
    if (e.Key == Key.LeftShift || e.Key == Key.RightShift || e.Key == Key.LeftCtrl || e.Key == Key.RightCtrl || e.Key == Key.LeftAlt || e.Key == Key.RightAlt || e.Key == Key.LWin || e.Key == Key.RWin)
    {
        return;
    }
    bool IsWinDown = e.KeyboardDevice.IsKeyDown(Key.LWin) | e.KeyboardDevice.IsKeyDown(Key.RWin);
    bool IsCtrlDown = e.KeyboardDevice.IsKeyDown(Key.LeftCtrl) | e.KeyboardDevice.IsKeyDown(Key.RightCtrl);
    bool IsAltDown = e.KeyboardDevice.IsKeyDown(Key.LeftAlt) | e.KeyboardDevice.IsKeyDown(Key.RightAlt);
    bool IsShiftDown = e.KeyboardDevice.IsKeyDown(Key.LeftShift) | e.KeyboardDevice.IsKeyDown(Key.RightShift);
    if (IsWinDown | IsCtrlDown | IsAltDown | IsShiftDown)
    {
        (sender as TextBox).Text =
          (IsWinDown ? "Windows + " : "") +
          (IsCtrlDown ? "Control + " : "") +
          (IsAltDown ? "Alt + " : "") +
          (IsShiftDown ? "Shift + " : "") +
          e.Key.ToString();
    }
}

It is saving the hotkey that the user types as KeyEventArgs.Key.ToString() but I need to save it as such that I can pass it to the “keys” parameter in SendKeys.Send() method easily.

Can anyone suggest how do I do this?

I used the SendInput API to send keystrokes and used the KeyInterop.VirtualKeyFromKey function to convert the key from System.Windows.Input.Key to Virtual Key code.
