Nhibernate映射内部类和InternalsVisibleTo [英] Nhibernate mapped internal classes and InternalsVisibleTo

问题描述

我的代理生成器无法为内部映射的Nhibernate类生成代理.我试过使用assemblyinfo.cs中的InternalsVisibleTo将它们添加为可见的，但似乎不起作用.更糟糕的是，我不知道如何分辨我是否成功地对想要的代理程序集结了朋友，因为如果我在assemblyinfo.cs中的代理程序集公钥中更改了一些数字，则不会引发任何错误.

错误:

测试方法TestProject1.UnitTest1.TestMethod1引发异常: NHibernate.HibernateException:创建代理实例失败---> Castle.DynamicProxy.Generators.GeneratorException:类型不是公共的，因此无法生成代理.类型:BaseSystemCore.Domain.Lot

StackTrace:

Castle.DynamicProxy.DefaultProxyBuilder.AssertValidType(类型目标) Castle.DynamicProxy.DefaultProxyBuilder.CreateClassProxy(类型classToProxy，类型[] AdditionalInterfacesToProxy，ProxyGenerationOptions选项) Castle.DynamicProxy.ProxyGenerator.CreateClassProxy(Type classToProxy，Type [] AdditionalInterfacesToProxy，ProxyGenerationOptions选项，Object []构造函数参数，IInterceptor []拦截器) NHibernate.ByteCode.Castle.ProxyFactory.GetProxy(对象ID，ISessionImplementor会话) NHibernateUtilities.BaseUnitOfWork.handleException(Exception e)in C:\ Users \ Isaac.G \ Desktop \ svn.bolinger.ca \ Library Projects \ NHibernateUtilities \ NHibernateUtilities \ BaseUnitOfWork.cs:871行 C:\ Users \ Isaac.G \ Desktop \ svn.bolinger.ca \ Library Projects \ NHibernateUtilities \ NHibernateUtilities \ BaseUnitOfWork.cs中的NHibernateUtilities.BaseUnitOfWork.getAllT:第115行 C:\ Users \ Isaac.G \ Desktop \ svn.bolinger.ca \ Library Projects \ BaseSystemCore \ TestProject1 \ UnitTest1.cs中的TestProject1.UnitTest1.TestMethod1():第71行

有人有没有以前工作过?

解决方案

NHibernate 3.2内置了代理提供程序.我简要地查看了源代码，似乎它们使用了以下格式:{0} ProxyAssembly.其中{0}是惰性映射类的类型名称.我还没有测试过.尝试在您的AssemblyInfo.cs中添加以下内容，并将{0}替换为您的惰性类名称:

[assembly: InternalsVisibleTo("{0}ProxyAssembly")]

如果您仍然想使用旧版本的NHibernate，则可以尝试使用此版本(适用于城堡字节码提供程序):

[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")]

DynamicProxyGenAssembly2是由Castle快速生成的临时程序集.它包含从映射的类(代理)派生的类.

My proxy generator is having trouble generating proxies for internal mapped Nhibernate classes. I have tried adding them as visible using InternalsVisibleTo in assemblyinfo.cs but it doesn't seem to work. Worse, I don't know how to tell if I've even successfully managed to friend the proxy assemblies I want to because if I change a few numbers in the proxy assemblies public key in assemblyinfo.cs there is no error thrown.

Error:

Test method TestProject1.UnitTest1.TestMethod1 threw exception: NHibernate.HibernateException: Creating a proxy instance failed ---> Castle.DynamicProxy.Generators.GeneratorException: Type is not public, so a proxy cannot be generated. Type: BaseSystemCore.Domain.Lot

StackTrace:

Castle.DynamicProxy.DefaultProxyBuilder.AssertValidType(Type target) Castle.DynamicProxy.DefaultProxyBuilder.CreateClassProxy(Type classToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) Castle.DynamicProxy.ProxyGenerator.CreateClassProxy(Type classToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, Object[] constructorArguments, IInterceptor[] interceptors) NHibernate.ByteCode.Castle.ProxyFactory.GetProxy(Object id, ISessionImplementor session) NHibernateUtilities.BaseUnitOfWork.handleException(Exception e) in C:\Users\Isaac.G\Desktop\svn.bolinger.ca\Library Projects\NHibernateUtilities\NHibernateUtilities\BaseUnitOfWork.cs: line 871 NHibernateUtilities.BaseUnitOfWork.getAllT in C:\Users\Isaac.G\Desktop\svn.bolinger.ca\Library Projects\NHibernateUtilities\NHibernateUtilities\BaseUnitOfWork.cs: line 115 TestProject1.UnitTest1.TestMethod1() in C:\Users\Isaac.G\Desktop\svn.bolinger.ca\Library Projects\BaseSystemCore\TestProject1\UnitTest1.cs: line 71

Has anyone ever got this to work before?

Thanks

解决方案

NHibernate 3.2 has built in proxy provider. I briefly look at the sources at it seems like they use this format: {0}ProxyAssembly. Where {0} is a type name for lazy mapped class. I have not tested it though. Try adding following to your AssemblyInfo.cs and replace {0} with your lazy class name:

[assembly: InternalsVisibleTo("{0}ProxyAssembly")]

If you still want to use older version of NHibernate you can try using this (for castle byte code provider):

[assembly: InternalsVisibleTo("DynamicProxyGenAssembly2")]

DynamicProxyGenAssembly2 is a temporary assembly that gets generated on the fly by Castle. It contains classes derived from your mapped classes (proxies).
