我是NHibernate的新手。我正在尝试将此 ORM 与 SQLite 一起使用。我有以下内容： 项目

产品.cs

namespace Stock.Models.Classes
{
    class Product
    {
        public virtual string Name {get; set;}
        public virtual int Id { get; set; }
        public virtual decimal Price { get; set; }
        public virtual decimal Quantity { get; set; }
    }
}

产品.hbm.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                  assembly="Stock.Models"
                  namespace="Stock.Models.Classes">
  <class name="Product" table="products">
    <id name="Id">
      <generator class="int" />
    </id>
    <property name="Name" />
    <property name="Price" />
    <property name="Quantity" />
  </class>
</hibernate-mapping>

休眠.cfg.xml

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
    <property name="connection.driver_class">NHibernate.Driver.SQLite20Driver</property>
    <property name="connection.connection_string">Data Source=nhibernate.db;Version=3</property>
    <property name="dialect">NHibernate.Dialect.SQLiteDialect</property>
    <property name="query.substitutions">true=1;false=0</property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration>

我正在尝试在 Program.cs 中进行测试。 程序.cs

namespace Stock
{
    static class Program
    {
        /// <summary>
        /// The main entry point for the application.
        /// </summary>
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            //Application.Run(new Form1());
            var cfg = new Configuration();
            cfg.Configure();
                cfg.AddAssembly(typeof(Product).Assembly);
        }
    }
}

在运行时，应用程序会在cfg.AddAssembly(typeof(Product).Assembly);弹出窗口Could not compile the mapping document: Stock.Models.Mappings.Product.hbm.xml和控制台中显示消息：

The thread 'vshost.LoadReference' (0x10a8) has exited with code 0 (0x0).

A first chance exception of type 'NHibernate.MappingException' occurred in NHibernate.dll

如果我在Program.cs添加一个 try/catch ：

 try
    {
        cfg.AddAssembly(typeof(Product).Assembly);
    }
 catch (Exception e) { Console.WriteLine(e); }

我得到（控制台）：

XML 文件设置为Embedded Resource和Copy Always。为什么不编译映射文件Stock.Models.Mappings.Product.hbm.xml？是文件格式问题还是库dll问题？

好吧，该Stock.Models程序集不存在。唯一存在的程序集是Stock，因此您需要相应地更改映射文件：

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                  assembly="Stock"
                  namespace="Stock.Models.Classes">

尽管我的映射文件是正确的，但我得到了同样的错误。

结果发现文件夹中不存在更新的程序集C:\inetpub\wwwroot\wss\VirtualDirectories\<port>\bin。当我手动复制它们时，它起作用了。

我没有解释为什么他们还没有被复制，或者即使他们应该被复制，我只是发布这个作为答案，因为它解决了我的问题，我还没有看到它记录在其他任何地方在线.

您应该在 hbm.xml file.for 中添加程序集和命名空间，以查找 typeof(yourModel).Assembly 使用的程序集名称并检查 fullName。程序集和类的名称不相同。

我有同样的问题。它在“程序集”和“命名空间”中。我为解决它所做的就是在您的示例中将两者命名为“Stock”。

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
                  assembly="Stock"
                  namespace="Stock">
