Answer 1

右击解决方案里的DTO.XML映射文件-属性-生成操作-嵌入的资源。再试试。

Answer 2

Web.Config里面需要配置NHibernate信息的，配置如下：<?xml version="1.0"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="connection.connection_string">Server=ServerName;initial catalog=DataBaseName;user=sa;password=password</property>
<property name="show_sql">true</property>
<property name="hbm2ddl.auto">none</property>
<mapping assembly="Model"/> </session-factory>
</hibernate-configuration>
</configSections>

Answer 3

配置了NHibernate。config
配置如下：
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string_name">Connection String</property>
    <property name="connection.connection_string">Server=localhost;initial catalog=lhy;Integrated Security=SSPI</property>
    <property name="adonet.batch_size">10</property>
    <property name="show_sql">true</property>
    <property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property>
    <property name="use_outer_join">true</property>
    <property name="command_timeout">300</property>
    <property name="query.substitutions">true 1,false 0,yes 'Y',no 'N'</property>    <mapping assembly="SK.DTO.Domain" />
  </session-factory>
</hibernate-configuration>

把DTO.xml改成Customer.hbm.xml呢？
