GetType

Hi

I have an OrderStatus object that is loaded via nhibernate. I am trying to do some comparisons on it based on its type, but instead of seeing the type i am looking for, I am getting CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1.

Is there a way to determine the type?

Here is the output from GetType()

Code:

? status.GetType()
{Name = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1" FullName = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1"}
    [System.RuntimeType]: {Name = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1" FullName = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1"}
    base {System.Reflection.MemberInfo}: {Name = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1" FullName = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1"}
    Assembly: {DynamicAssemblyProxyGen, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null}
    AssemblyQualifiedName: "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1, DynamicAssemblyProxyGen, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null"

    ContainsGenericParameters: false
    DeclaringMethod: 'status.GetType().DeclaringMethod' threw an exception of type 'System.InvalidOperationException'
    DeclaringType: null
    FullName: "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1"
    GenericParameterAttributes: 'status.GetType().GenericParameterAttributes' threw an exception of type 'System.InvalidOperationException'
    GenericParameterPosition: 'status.GetType().GenericParameterPosition' threw an exception of type 'System.InvalidOperationException'
    GUID: {efb52c8d-8bb8-32ce-bb8e-5f0ecb58f2ac}

    IsVisible: true
    MemberType: TypeInfo
    Module: {DynamicAssemblyProxyGen}
    Namespace: null
    ReflectedType: null
    StructLayoutAttribute: {System.Runtime.InteropServices.StructLayoutAttribute}
    TypeHandle: {System.RuntimeTypeHandle}
    TypeInitializer: null
    UnderlyingSystemType: {Name = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1" FullName = "CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1"}

Code:

? status
{Orders.Core.OrderStatusPending}

And here is the output when i do a quick ? status
    
[CProxyTypeOrders_CoreOrderStatusCore_NHibernate_ProxyINHibernateProxy1]: {Orders.Core.OrderStatusPending}
    _ISSStatusId: ""
    _OrderStatusDescription: ""
    _OrderStatusId: 0
    ISSStatusId: null
    OrderStatusDescription: "Pending   "
    OrderStatusId: 1

The IDE can "see" it, so its possible, but can anyone tell me how to get "Orders.Core.OrderStatusPending" through code?

Thanks for any help
Joe

Found the answer just as after I hit post

<many-to-one name="OrderStatusInformation" class="OrderStatus" column="order_status_id" cascade="none" lazy="false" insert="false" update="false" />

Lazy loading needs to be disabled.

I'd still be interesting in learning how to determine the type.

Thanks
Joe

If you call ISession.Get() instead of ISession.Load(), you will never get a proxy. I explained it a bit here:
http://forum.hibernate.org/viewtopic.ph ... 24#2358724

If I am not mistaken, the proxy should be a direct descendant of your OrderStatusPending class. Calling GetType().Parent should give you the Type of OrderStatusPending class. Be aware though, ISession.Load() does not always return a proxy: if you called Get() and the entity has been loaded and cached in the session, calling Load() will return the unproxied entity.

You can can also use NHibernateUtil.GetClass(targetObject) and it will return the type of the object. If the object is lazy it may need to initialize it from the database to determine the type.
