我有一个使用nhibernate的网站，它托管在一个共享的网络主机上。

我已经通过“NHibernate.Cfg.Environment.UseReflectionOptimizer=false；”禁用了延迟加载，因为我的主机上不允许反射。

但现在我对nhibernate有另一个问题：

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:

   System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant) +54

每次使用nhibernate（用于数据库访问）时都会发生此错误。我已经将Nhibernate降级为1.2，现在只为映射文件中声明了关系的对象的更新和删除操作抛出异常。

我认为错误是由Castle.DynamicProxy.dll引起的。但是如何完全禁用代理？我已经在lazy=“false”上设置了映射中的所有对象和关系，我已经设置了默认lazy=”false“

在nhibernate助手中，我还设置了nhibernate.Cfg.Environment.BytecodeProvider=null，但这没有帮助。
