C# 什么是PostMessage所必需的库？

我试图在C#中模拟按键，我得到了以下错误：

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使用系统的

。（一些东西）

但是什么呢？谢谢您的帮助。

它位于User32.Dll中。您需要自己指定

下面是一个示例类，假设

Forward（）

在类

MyClass

中

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);
}

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;

它们应该是windows消息值。如果您想要一个友好的枚举，您必须编写自己的枚举，或者在线查找。它们应该是windows消息值。如果你想要一个友好的枚举，你必须自己写，或者在网上找到一个。
