C#操作注册表

x32软件在x64系统下操作注册表，会自动转向到Wow6432Node,为了控制不转向，使用以下代码：

/// <summary>        /// 获得根节点的句柄，常数是固定的        /// </summary>        /// <param name="hive"></param>        /// <returns></returns>        public static IntPtr GetHiveHandle(RegistryHive hive)        {            IntPtr preexistingHandle = IntPtr.Zero;            IntPtr HKEY_CLASSES_ROOT = new IntPtr(-2147483648);            IntPtr HKEY_CURRENT_USER = new IntPtr(-2147483647);            IntPtr HKEY_LOCAL_MACHINE = new IntPtr(-2147483646);            IntPtr HKEY_USERS = new IntPtr(-2147483645);            IntPtr HKEY_PERFORMANCE_DATA = new IntPtr(-2147483644);            IntPtr HKEY_CURRENT_CONFIG = new IntPtr(-2147483643);            IntPtr HKEY_DYN_DATA = new IntPtr(-2147483642);            switch (hive)            {                case RegistryHive.ClassesRoot: preexistingHandle = HKEY_CLASSES_ROOT; break;                case RegistryHive.CurrentUser: preexistingHandle = HKEY_CURRENT_USER; break;                case RegistryHive.LocalMachine: preexistingHandle = HKEY_LOCAL_MACHINE; break;                case RegistryHive.Users: preexistingHandle = HKEY_USERS; break;                case RegistryHive.PerformanceData: preexistingHandle = HKEY_PERFORMANCE_DATA; break;                case RegistryHive.CurrentConfig: preexistingHandle = HKEY_CURRENT_CONFIG; break;                case RegistryHive.DynData: preexistingHandle = HKEY_DYN_DATA; break;            }            return preexistingHandle;        }

使用：

/// <summary>        /// 操作注册表        /// </summary>        /// <param name="hive">根级别的名称</param>        /// <param name="path">不包括根级别的名称</param>        /// <param name="parameters">项/（值/值类型） 参数</param>        /// <param name="view">注册表视图</param>        [RegistryPermissionAttribute(SecurityAction.LinkDemand, Unrestricted = true)]        public static void OperateReg(RegistryHive hive, string path, Dictionary<string, string[]> parameters, RegistryView view)        {            SafeRegistryHandle handle = new SafeRegistryHandle(GetHiveHandle(hive), true);            RegistryKey r = RegistryKey.FromHandle(handle, view).CreateSubKey(path, RegistryKeyPermissionCheck.ReadWriteSubTree);  //一般情况是使用如下代码：        //RegistryKey rk = Registry.LocalMachine.CreateSubKey(path);           if (parameters == null && parameters.Count <= 0)                return;            List<string> keys = parameters.Keys.ToList();            for (int i = 0; i < parameters.Count; i++)            {   //string to RegistryValueKind                RegistryValueKind rv = (RegistryValueKind)Enum.Parse(typeof(RegistryValueKind), parameters[keys[i]][1].ToString(), true);                r.SetValue(keys[i], parameters[keys[i]][0], rv);            }        }

例子：

        public static void RegisterScreenCapture(string targetDir, string guid, bool is64BitLync)        {            if (string.IsNullOrEmpty(guid))                guid = "{541a4dc3-50dc-4b4f-a38d-0ed1d360ca6b}";            Dictionary<string, string[]> paraCapture = new Dictionary<string, string[]>();            paraCapture["Name"] = new string[] { "ScreenCapture", RegistryValueKind.String.ToString() };            paraCapture["Path"] = new string[] { string.Format("{0}IcoLync.ScreenCapture.exe", targetDir), RegistryValueKind.String.ToString() };            paraCapture["Extensiblemenu"] = new string[] { "ConversationWindowActions", RegistryValueKind.String.ToString() };            paraCapture["SessionType"] = new string[] { "0", RegistryValueKind.DWord.ToString() };            RegistryView rv;            if (is64BitLync)                rv = RegistryView.Registry64;            else                rv = RegistryView.Default;            OperateReg(RegistryHive.LocalMachine, string.Format(@"SOFTWARE\Microsoft\Office\15.0\Lync\SessionManager\Apps\{0}", guid), paraCapture, rv);        }

刚才经过测试，不需要GetHiveHandl()也行(我也不知道什么需要)；

OperateReg()方法中一二行代码改为

RegistryKey r = RegistryKey.OpenBaseKey(hive, view).CreateSubKey(path, RegistryKeyPermissionCheck.ReadWriteSubTree);
