我在现有应用程序中添加了一个新表.hbm.xml文件和class。其他表中的数据也显示在页面上。
对于此新表格，不会保存和显示数据。
NHibernate忽略它。我没有收到任何错误消息。我还更改了新table文件中的hbm.xml值，但没有错误。但是，如果我在其他文件中更改table，则应用程序会抛出异常。看起来它不知道新文件。我将此文件设为Embedded Resource。我正在使用VS 2010，MVC和Oracle以及C#
这是xml和类。提前谢谢。

我和你最近面临的类似问题。在VS 2012中，文件重命名的工作方式如下：1）通过单击选择 .hbm.xml 文件... 2）选择文件后缀之前的部分。 3）键入新名称，而后缀不变。
诀窍是NHibernate文件嵌入式资源有两个后缀：.hbm.xml。配置如下：
<mapping assembly="CaseMgr.Model" />
适用于惯例：搜索扩展名为 .hbm.xml 的嵌入资源。所以，如果您的新文件是
一定是
缺少的 .hbm 在我的情况下是原因，为什么NHibernate根本不知道该文件，并且如果它出错则没有抛出异常......但它没有被加载不可用
EXTENDED
如果我的方案正确：一个VS项目（库），许多.hbm.xml文件，都是嵌入式资源，所有这些都是有效的。
如果我正确地重现您的问题，您应该：
运行IL Spy检查dll是否包含所有预期的嵌入资源
进行如下测试：
var factory = ... //get your NHibernate factory
var entityType = typeof(CaseMgr.Model.BusinessObjects.PatLiverPeld);
var persister = factory.GetClassMetadata(entityType) as AbstractEntityPersister;
Assert.IsTrue(persister != null)
如果您将看到资源，并且没有持久性...尝试将映射移动到现有工作文件（一个.hbm.xml文件中的两个类）。任何其他情况都很难发生，因为在“worng”配置类映射期间缺少异常（如问题中所述）
