当我将我的应用程序上传到服务器进行测试时,我收到了这个奇怪的莫名其妙的错误.从我研究的,它似乎是由冲突的MySql.Data引起的,我上传的副本属于:6.3.7.0.

我怎么能解决这个问题？我想只是把它放在垃圾箱里会"覆盖"GAC中的那个？

我有这个ASP.NET MVC3代码,由Spring和Fluent NHibernate(NHIB 3.1)提供支持

我有这个错误:

这是我的错误：

NHibernate.ObjectNotFoundException: No row with the given identifier exists[Project.Core.Entities.User#(GUID)]
at Hibernate.Impl.SessionFactoryImpl.DefaultEntityNotFoundDelegate.HandleEntityNotFound(String entityName, Object id) 
at NHibernate.Event.Default.DefaultLoadEventListener.Load(LoadEvent event, IEntityPersister persister, EntityKey keyToLoad, LoadType options)

该系统的一位用户偶然遇到了这个错误，这对我来说完全没有意义。我所知道的：

1. 教师表引用用户表。
2. 不知何故，教师表中有一行引用用户表中的行，但用户表中不存在该行。

知道为什么会发生这种情况吗？请指教！

改写我的 Qn：

我知道该错误是什么意思，但我似乎不明白是什么导致了丢失的用户行？我已将其全部放在 Cascade.ALL 上。我认为这与删除无关。上述情况可能会发生哪些情况？

编辑2：

请参考 FNH 的映射：这有什么问题吗？

public void Override(AutoMapping<Teacher> mapping)
    {
        mapping.References(x => x.User).Cascade.All().Not.LazyLoad();
    }

谢谢！

我试图在ASP.NET MVC 4上执行此操作:

MemoryStream mem = new MemoryStream();
        using (WordprocessingDocument wordDoc =
            WordprocessingDocument.Create(mem, DocumentFormat.OpenXml.WordprocessingDocumentType.Document, true))
        {
            // instantiate the members of the hierarchy
            Document doc = new Document();
            Body body = new Body();
            Paragraph para = new Paragraph();
            Run run = new Run();
            Text text = new Text() { Text = "The OpenXML SDK rocks!" };

            // put the hierarchy together
            run.Append(text);
            para.Append(run);
            body.Append(para);
            doc.Append(body);

            //wordDoc.Close();

            ///wordDoc.Save();
        }


return File(mem.ToArray(), "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "ABC.docx");

然而,ABC.docx打开已损坏,即使修复它也无法打开.

有任何想法吗？
