我有一个使用 nhibernate 的网站，它托管在共享网络主机上。

我已经禁用了延迟加载槽“NHibernate.Cfg.Environment.UseReflectionOptimizer = false;” 因为我的主机不允许反射。

但是现在我有另一个关于 nhibernate 的问题：

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Request failed.

Source Error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

Stack Trace:

[SecurityException: Request failed.]
   System.Security.CodeAccessSecurityEngine.ThrowSecurityException(RuntimeAssembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandleInternal rmh, SecurityAction action, Object demand, IPermission permThatFailed) +168
   System.Security.CodeAccessSecurityEngine.ThrowSecurityException(Object assemblyOrString, PermissionSet granted, PermissionSet refused, RuntimeMethodHandleInternal rmh, SecurityAction action, Object demand, IPermission permThatFailed) +100
   System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet refused, PermissionSet demands, RuntimeMethodHandleInternal rmh, Object assemblyOrString, SecurityAction action, Boolean throwException) +278
   System.Security.PermissionSetTriple.CheckSetDemand(PermissionSet demandSet, PermissionSet& alteredDemandset, RuntimeMethodHandleInternal rmh) +69
   System.Security.PermissionListSet.CheckSetDemand(PermissionSet pset, RuntimeMethodHandleInternal rmh) +156
   System.Security.PermissionListSet.DemandFlagsOrGrantSet(Int32 flags, PermissionSet grantSet) +33
   System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant, CompressedStack securityContext) +128
   System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant) +54

每次使用 nhibernate 时都会发生此错误（用于数据库访问）。我已将 Nhibernate 降级为 1.2，现在仅针对在映射文件中声明了关系的对象的更新和删除操作引发异常。

我认为该错误是由 Castle.DynamicProxy.dll 引起的。但是如何完全禁用代理？我已将映射中的所有对象和关系lazy="false"设置为default-lazy="false"

在我也设置了休眠助手中，NHibernate.Cfg.Environment.BytecodeProvider = null;但这无济于事。

如果您尝试以中等信任度设置环境（因为您使用的是共享提供商），请查看这个现有的 SO 答案：

NHibernate 在已部署的 Web 应用程序上的“安全”问题

具体来说，NHibernate 的 Wiki 链接：http: //nhforge.org/wikis/howtonh/run-in-medium-trust.aspx
