有什么可以使用NHibernate和Firebird数据库时,会导致在C#下面的错误?

解决方案

只是为了保持完整性。唯一的例外:

  

索引超出范围…

与NHibernate写操作主要是指:有加倍列映射。

通常相结合的<性> <许多一对一> 。同时检查:

NHibernate的映射索引超出范围

What can cause the following error in c# when using NHibernate and Firebird database?

解决方案

Just for completeness. The exception:

Index was out of range…

with NHibernate WRITE operation mostly means: there is doubled column mapping.

Usually combination of the <property> and <many-to-one>. Also check:

NHibernate mapping index out of range
