Question

我正在尝试模拟C＃中的按键，我收到了这些错误：

Error   2   The name 'WM_KEYDOWN' does not exist in the current context c:\users\frk\documents\visual studio 2010\Projects\HaxBot3\HaxBot3\Form1.cs 28  52  HaxBot3

这是给出错误的代码：

public static void Forward()
        {
            Process[] processes = Process.GetProcessesByName("test");

            foreach (Process proc in processes)
            {
                PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_CONTROL, 0);
                PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_ALT, 0);
                PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VK_RIGHT, 0);
            }
        }//Fprward

我想我必须添加一些using System.(something)但是什么？谢谢你的帮助。

Answer 1

您需要自己定义。

[DllImport("user32.dll")]
public static extern bool PostMessage(IntPtr hWnd, uint msg, uint wParam, IntPtr lParam);

public const uint WM_KEYDOWN = 0x0100;
public const uint VK_RIGHT = 27;
public const uint VK_CONTROL = 11;
public const uint VK_ALT = 12;

Answer 2

它位于User32.Dll中。您需要自己指定。 Visit this PInvoke.net page on PostMessage for more information

以下是假设Forward()位于班级MyClass中的示例类。

public static class MyClass
{
  public static void Forward()
  {
     /* snip */
  }

  [return: MarshalAs(UnmanagedType.Bool)]
  [DllImport("user32.dll", SetLastError = true)]
  static extern bool PostMessage(HandleRef hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
}

C＃PostMessage的必备库是什么？
