求一个C#键盘钩子的程序

Question

在网上搜了好多钩子的程序，复制进我的电脑总是运行不了，求一个C#键盘钩子完整程序，要可以在vs2013上运行的完整程序，据说知道已支持文件上传与下载，不让我输邮箱。。。拜托上传一下，不行的话，在百度云里分享给我地址也行

使用钩子之前，需要使用SetWindowsHookEx()函数创建钩子，使用完毕之后要UnhookWindowsHookEx()函数卸载钩子，“钩”到消息后操作系统会自动调用在创建钩子时注册的回调函数来处理消息，处理完后调用CallNextHookEx()函数等待或处理下一条消息。

对于键盘钩子，钩子类型为WH_KEYBOARD_LL=13，只需要设置SetWindowsHookEx的idHook参数为13即可“钩”到键盘消息。关于钩子类型的资料见参考资料--钩子类型。

添加Win32Api引用，代码如下：
public class Win32Api
{
#region 常数和结构
public const int WM_KEYDOWN = 0x100;
public const int WM_KEYUP = 0x101;
public const int WM_SYSKEYDOWN = 0x104;
public const int WM_SYSKEYUP = 0x105;
public const int WH_KEYBOARD_LL = 13;

[StructLayout(LayoutKind.Sequential)] //声明键盘钩子的封送结构类型
public class KeyboardHookStruct
{
public int vkCode; //表示一个在1到254间的虚似键盘码
public int scanCode; //表示硬件扫描码
public int flags;
public int time;
public int dwExtraInfo;
}
#endregion
#region Api
public delegate int HookProc(int nCode, Int32 wParam, IntPtr lParam);
//安装钩子的函数
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern int SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hInstance, int threadId);

//卸下钩子的函数
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern bool UnhookWindowsHookEx(int idHook);

//下一个钩挂的函数
[DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
public static extern int CallNextHookEx(int idHook, int nCode, Int32 wParam, IntPtr lParam);

[DllImport("user32")]
public static extern int ToAscii(int uVirtKey, int uScanCode, byte[] lpbKeyState, byte[] lpwTransKey, int fuState);

[DllImport("user32")]
public static extern int GetKeyboardState(byte[] pbKeyState);

[DllImport("kernel32.dll", CharSet = CharSet.Auto,CallingConvention = CallingConvention.StdCall)]
public static extern IntPtr GetModuleHandle(string lpModuleName);
#endregion

添加新建类KeyboardHook，封装键盘钩子，代码如下：
public class KeyboardHook
{
int hHook;
Win32Api.HookProc KeyboardHookDelegate;
public event KeyEventHandler OnKeyDownEvent;
public event KeyEventHandler OnKeyUpEvent;
public event KeyPressEventHandler OnKeyPressEvent;
public KeyboardHook() { }
public void SetHook()
{
KeyboardHookDelegate = new Win32Api.HookProc(KeyboardHookProc);
Process cProcess = Process.GetCurrentProcess();
ProcessModule cModule = cProcess.MainModule;
var mh = Win32Api.GetModuleHandle(cModule.ModuleName);
hHook = Win32Api.SetWindowsHookEx(Win32Api.WH_KEYBOARD_LL, KeyboardHookDelegate, mh, 0);
}
public void UnHook()
{
Win32Api.UnhookWindowsHookEx(hHook);
}
private List<Keys> preKeysList = new List<Keys>();//存放被按下的控制键，用来生成具体的键
private int KeyboardHookProc(int nCode, Int32 wParam, IntPtr lParam)
{
//如果该消息被丢弃（nCode<0）或者没有事件绑定处理程序则不会触发事件
if ((nCode >= 0) && (OnKeyDownEvent != null || OnKeyUpEvent != null || OnKeyPressEvent != null))
{
Win32Api.KeyboardHookStruct KeyDataFromHook = (Win32Api.KeyboardHookStruct)Marshal.PtrToStructure(lParam, typeof(Win32Api.KeyboardHookStruct));
Keys keyData = (Keys)KeyDataFromHook.vkCode;
//按下控制键
if ((OnKeyDownEvent != null || OnKeyPressEvent != null) && (wParam == Win32Api.WM_KEYDOWN || wParam == Win32Api.WM_SYSKEYDOWN))
{
if (IsCtrlAltShiftKeys(keyData) && preKeysList.IndexOf(keyData) == -1)
{
preKeysList.Add(keyData);
}
}
//WM_KEYDOWN和WM_SYSKEYDOWN消息，将会引发OnKeyDownEvent事件
if (OnKeyDownEvent != null && (wParam == Win32Api.WM_KEYDOWN || wParam == Win32Api.WM_SYSKEYDOWN))
{
KeyEventArgs e = new KeyEventArgs(GetDownKeys(keyData));

OnKeyDownEvent(this, e);
}
//WM_KEYDOWN消息将引发OnKeyPressEvent
if (OnKeyPressEvent != null && wParam == Win32Api.WM_KEYDOWN)
{
byte[] keyState = new byte[256];
Win32Api.GetKeyboardState(keyState);

byte[] inBuffer = new byte[2];
if (Win32Api.ToAscii(KeyDataFromHook.vkCode, KeyDataFromHook.scanCode, keyState, inBuffer, KeyDataFromHook.flags) == 1)
{
KeyPressEventArgs e = new KeyPressEventArgs((char)inBuffer[0]);
OnKeyPressEvent(this, e);
}
}
//松开控制键
if ((OnKeyDownEvent != null || OnKeyPressEvent != null) && (wParam == Win32Api.WM_KEYUP || wParam == Win32Api.WM_SYSKEYUP))
{
if (IsCtrlAltShiftKeys(keyData))
{
for (int i = preKeysList.Count - 1; i >= 0; i--)
{
if (preKeysList[i] == keyData) { preKeysList.RemoveAt(i); }
}
}
}
//WM_KEYUP和WM_SYSKEYUP消息，将引发OnKeyUpEvent事件
if (OnKeyUpEvent != null && (wParam == Win32Api.WM_KEYUP || wParam == Win32Api.WM_SYSKEYUP))
{
KeyEventArgs e = new KeyEventArgs(GetDownKeys(keyData));
OnKeyUpEvent(this, e);
}
}
return Win32Api.CallNextHookEx(hHook, nCode, wParam, lParam);
}
//根据已经按下的控制键生成key
private Keys GetDownKeys(Keys key)
{
Keys rtnKey = Keys.None;
foreach (Keys i in preKeysList)
{
if (i == Keys.LControlKey || i == Keys.RControlKey) { rtnKey = rtnKey | Keys.Control; }
if (i == Keys.LMenu || i == Keys.RMenu) { rtnKey = rtnKey | Keys.Alt; }
if (i == Keys.LShiftKey || i == Keys.RShiftKey) { rtnKey = rtnKey | Keys.Shift; }
}
return rtnKey | key;
}

private Boolean IsCtrlAltShiftKeys(Keys key)
{
if (key == Keys.LControlKey || key == Keys.RControlKey || key == Keys.LMenu || key == Keys.RMenu || key == Keys.LShiftKey || key == Keys.RShiftKey) { return true; }
return false;
}
}

在主窗体中添加代码,如下：
public MainForm()
{
InitializeComponent();
}
KeyboardHook kh;
private void Form1_Load(object sender, EventArgs e)
{
kh = new KeyboardHook();
kh.SetHook();
kh.OnKeyDownEvent += kh_OnKeyDownEvent;
}
void kh_OnKeyDownEvent(object sender, KeyEventArgs e)
{
if (e.KeyData == (Keys.S | Keys.Control)) { this.Show(); }//Ctrl+S显示窗口
if (e.KeyData == (Keys.H | Keys.Control)) { this.Hide(); }//Ctrl+H隐藏窗口
if (e.KeyData == (Keys.C | Keys.Control)) { this.Close(); }//Ctrl+C 关闭窗口
if (e.KeyData == (Keys.A | Keys.Control | Keys.Alt)) { this.Text = "你发现了什么？"; }//Ctrl+Alt+A
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
kh.UnHook();
}
}
6
代码添加完毕后，运行调试。当按下Ctrl+H是窗口隐藏，当按下Ctrl+S窗口显示，当按下Ctrl+C时窗口关闭，开着QQ按下Ctrl+Alt+A时...（会出现什么呢？这个要你自己去发现哦）。追问

这些代码我原来都是看过的，我要源代码文件。。。
