Question

我正在使用NHibernate 3.3和vb.net 我试图通过代码映射，但它导致无法创建接口的实例。代码如下。

Dim cfg As New Configuration()
                cfg.Properties.Add(NHibernate.Cfg.Environment. _
                  ConnectionProvider, GetType(NHibernate.Connection. _
                  DriverConnectionProvider).AssemblyQualifiedName)

                cfg.Properties.Add(NHibernate.Cfg.Environment.Dialect, _
                  GetType(NHibernate.Dialect.MsSql2008Dialect). _
                  AssemblyQualifiedName)

                cfg.Properties.Add(NHibernate.Cfg.Environment.ConnectionDriver, _
                  GetType(NHibernate.Driver.SqlClientDriver). _
                  AssemblyQualifiedName)
                cfg.Properties.Add(NHibernate.Cfg.Environment.ConnectionStringName, _
  "myconnectionstring")

                cfg.Properties.Add(NHibernate.Cfg.Environment. _
                  ProxyFactoryFactoryClass, GetType _
                  (NHibernate.Bytecode.IProxyFactoryFactory). _
                  AssemblyQualifiedName)

                Dim s2 As NHibernate.ISessionFactory = cfg.BuildSessionFactory
                db = s2.OpenSession()

IproxyFactoryFactory发生

错误。我包括所有必需的引用，如NHibernate.Linq，NHibernate.dialect等请帮忙感谢

该行：

cfg.Properties.Add(NHibernate.Cfg.Environment. _
              ProxyFactoryFactoryClass, GetType _
              (NHibernate.Bytecode.IProxyFactoryFactory). _
              AssemblyQualifiedName)

ProxyFactoryFactoryClass是一个类，但是您指定了一个接口（NHibernate.Bytecode.IProxyFactoryFactory），将其更改为：

cfg.Properties.Add(NHibernate.Cfg.Environment. _
              ProxyFactoryFactoryClass, GetType _
              (NHibernate.Bytecode.DefaultProxyFactoryFactory). _
              AssemblyQualifiedName)

Nhibernate中的映射
