当你运行FrameWork时,出现以下错误.

System.Management thrown System.Management.ManagementException
访问遭到拒绝 
   在 System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode)
   在 System.Management.ManagementScope.InitializeGuts(Object o)
   在 System.Management.ManagementScope.Initialize()
   在 System.Management.ManagementObject.Initialize(Boolean getObject)
   在 System.Management.ManagementClass.GetInstances(EnumerationOptions options)
   在 System.Management.ManagementClass.GetInstances()
   在 FrameWork.Components.sys_FrameWorkInfoTable..ctor()
   在 FrameWork.CheckUpdate..ctor()
   在 FrameWork.FrameWorkPermission.app_Auth(Object sender, EventArgs e)
   在 System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
   在 System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

是由于你的服务器asp.net的运行权限低,导致asp.net进程无法访问System.Management类. 你可以找到FrameWork.Components.sys_FrameWorkInfoTable.cs文件,将其原来的构造函数

        /// <summary>        /// 构造函数        /// </summary>        public sys_FrameWorkInfoTable()        {            ManagementClass mc = new ManagementClass("Win32_Processor");            ManagementObjectCollection moc = mc.GetInstances();            foreach (ManagementObject mo in moc)            {                _S_RegsionGUID = mo.Properties["ProcessorId"].Value.ToString();                break;            }        }

修改为

      /// <summary>        /// 构造函数     /// </summary>        public sys_FrameWorkInfoTable()        {            ManagementClass mc = new ManagementClass("Win32_Processor");            try            {                ManagementObjectCollection moc = mc.GetInstances();                foreach (ManagementObject mo in moc)                {                    _S_RegsionGUID = mo.Properties["ProcessorId"].Value.ToString();                    break;                }            }            catch (Exception)            {                _S_RegsionGUID = Common.EnBase64(AppDomain.CurrentDomain.BaseDirectory);            }            finally {                mc.Dispose();            }        }
