模糊的NHibernate/Fluent NHibernate错误

Question

我在尝试构建会话工厂时遇到以下错误:

System.IndexOutOfRangeException: Index was outside the bounds of the 
array.

我正在对抗FNH主干和NH 2.0.1.有趣的是我能够编译我的映射(通过AutoPersistenceModel.CompileMappings)并将它们成功写入文件系统 - FNH不会抱怨.只有在尝试构建会话工厂时,所有内容都会变成kaboom,并且上面没有非常有用的错误消息.有人有任何想法吗？

Answer 1

我发现内部异常提供了更多细节.在我的情况下,我不得不将NHibernate.ByteCode.Castle.dll文件添加到引用.

Answer 2

流利的NHibernate本身很少直接向你抱怨.在内部,它只是为你构建你的HBM文件,所以如果你告诉它构建错误的话,那么NHibernate本身就会变得脾气暴躁.

如果您还没有,可能需要从导出映射文件开始,如下所示:

.Mappings(m => m.FluentMappings.AddFromAssemblyOf<MyClass>()
    .ExportTo("path")

然后你可以在那里挖掘,看看是否有问题.我记得曾经有过这样的错误,我认为这与映射的列数不匹配有关.这是我的映射中容易错过的错误之一,所以不幸的是我所能建议的是真正地搜索ExportTo任何没有意义的输出.
