我正在尝试在 C# 中模拟按键，但出现以下错误：

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东西using System.(something)但是什么？感谢帮助。

你需要自己定义这些。

[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;

它在 User32.Dll 中。您需要自己指定。访问此 PInvoke.net 页面以PostMessage获取更多信息。

这是一个示例类，假设Forward()在 class 中MyClass。

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);
}
