调试易

bool _exit = false;
            string[] subkeyNames;
            RegistryKey hkml = Registry.LocalMachine;
            RegistryKey software = hkml.OpenSubKey(@"SOFTWARE\Microsoft\Jet\4.0\Engines", true);            try
            {                subkeyNames = software.GetSubKeyNames();
                foreach (string keyName in subkeyNames)
                {                    if (keyName == "Excel")
                    {
                        RegistryKey aimdir = software.OpenSubKey("Excel", false);
                        subkeyNames = aimdir.GetValueNames();
                       
                        foreach (string strkeyName in subkeyNames)
                        {
                            if (strkeyName == "TypeGuessRows")
                            {
                               
                            }
                        }
                        return _exit;
                    }
                }
                return _exit;            }
            catch (Exception ex)
            {
                hkml.Close();
                software.Close();
                return false;
            }
上述是通过循环找到了"TypeGuessRows" 这个项，请问我如何获取 TypeGuessRows 对应的值？
