我在这里的sql关系http://i.stack.imgur.com/jOT5M.jpg
给我“MappingException,No persister for:NHiberDeneme.Sinifi”错误。我尝试了很多方法,我也嵌入了资源。
答案 0 :(得分:0)
有了这个错误,NHibernate会告诉你类映射有问题。 NHibernate要么找不到类映射,要么无法正确解析它。
通过查看它,映射文件中的类名似乎是错误的。
来自NHibernate关于class mapping
的文档:
name :持久化类的完全限定的.NET类名(或 接口),包括其程序集名称。
在您的代码中,您有类名:NHiberDeneme.Sinifi, NHiberDeneme.Program, NHiberDeneme
。这不是有效的.NET assembly qualified class name。如果您的程序集名称为NHiberDeneme
,则应该具有以下内容:
<class name="NHiberDeneme.Sinifi, NHiberDeneme" ... />
...如果程序集名称为NHiberDeneme.Program
,则映射应如下所示:
<class name="NHiberDeneme.Sinifi, NHiberDeneme.Program" ... />
