Senden Sie Schlüssel über SendInput in user32.dll
ich benutzedieses Brett als Tastatur für Demo-Zwecke.
Wie auch immer, um es kurz zu machen, bis auf wenige Fälle funktioniert alles einwandfrei. Ich sende Tastenanschläge mit demSendInput Funktion befindet sich in user32.dll.
So sieht mein Programm aus:
static void Main(string[] args)
{
Console.Write("Press enter an on the next secont the key combination shift+end will be send");
Console.Read();
Thread.Sleep(1000);
SendKeyDown(KeyCode.SHIFT);
SendKeyPress(KeyCode.END);
SendKeyUp(KeyCode.SHIFT);
Console.Read();
Console.Read();
}
[DllImport("user32.dll", SetLastError = true)]
private static extern uint SendInput(uint numberOfInputs, INPUT[] inputs, int sizeOfInputStructure);
/// <summary>
/// simulate key press
/// </summary>
/// <param name="keyCode"></param>
public static void SendKeyPress(KeyCode keyCode)
{
INPUT input = new INPUT {
Type = 1
};
input.Data.Keyboard = new KEYBDINPUT() {
Vk = (ushort)keyCode,
Scan = 0,
Flags = 0,
Time = 0,
ExtraInfo = IntPtr.Zero,
};
INPUT input2 = new INPUT {
Type = 1
};
input2.Data.Keyboard = new KEYBDINPUT() {
Vk = (ushort)keyCode,
Scan = 0,
Flags = 2,
Time = 0,
ExtraInfo = IntPtr.Zero
};
INPUT[] inputs = new INPUT[] { input, input2 };
if (SendInput(2, inputs, Marshal.SizeOf(typeof(INPUT))) == 0)
throw new Exception();
}
/// <summary>
/// Send a key down and hold it down until sendkeyup method is called
/// </summary>
/// <param name="keyCode"></param>
public static void SendKeyDown(KeyCode keyCode)
{
INPUT input = new INPUT{
Type = 1
};
input.Data.Keyboard = new KEYBDINPUT();
input.Data.Keyboard.Vk = (ushort)keyCode;
input.Data.Keyboard.Scan = 0;
input.Data.Keyboard.Flags = 0;
input.Data.Keyboard.Time = 0;
input.Data.Keyboard.ExtraInfo = IntPtr.Zero;
INPUT[] inputs = new INPUT[] { input };
if (SendInput(1, inputs, Marshal.SizeOf(typeof(INPUT))) == 0)
{
throw new Exception();
}
}
/// <summary>

/// </summary>
/// <param name="keyCode"></param>
public static void SendKeyUp(KeyCode keyCode)
{
INPUT input = new INPUT {
Type = 1
};
input.Data.Keyboard = new KEYBDINPUT();
input.Data.Keyboard.Vk = (ushort)keyCode;
input.Data.Keyboard.Scan = 0;
input.Data.Keyboard.Flags = 2;
input.Data.Keyboard.Time = 0;
input.Data.Keyboard.ExtraInfo = IntPtr.Zero;
INPUT[] inputs = new INPUT[] { input };
if (SendInput(1, inputs, Marshal.SizeOf(typeof(INPUT))) == 0)
throw new Exception();
}
Und hier sind die Strukturen, die ich online gefunden habe, die diese Methoden verwenden, und auch die Schlüsselcodes:(Beachten Sie, dass es wie viel Code aussieht und weil es viele Schlüsselcodes in einer Aufzählung gibt.)

So, jetzt ist meine Frage Warum erhalte ich beim Senden dieser Tastenkombination nicht die gleichen Ergebnisse wie bei einer echten Tastatur? 98% der Dinge funktionieren. Zum Beispiel kann ich:
SendKeyDown(KeyCode.SHIFT);
SendKeyPress(KeyCode.KEY_A );
SendKeyUp(KeyCode.SHIFT);
Und das wird ein Kapital A senden.
Soll ich eine andere Bibliothek verwenden?
Der Grund, warum ich diesen Ansatz mag, ist, dass ich nicht im Voraus weiß, ob der Benutzer eine Tastenkombination senden wird Zum Beispiel in Windows Forms Wenn ich das tue:
System.Windows.Forms.SendKeys.SendWait("+{end}"); das wird shift + end senden, aber vielleicht will der Benutzer nur shift senden ...
