C# 如何将nhibernate连接到本地SQLEXPRESS？

我在项目中有到数据库的简单连接：

public static string GetConnectionString()
        { 
            return @"Data Source=.\SQLEXPRESS;AttachDbFilename=" + HttpContext.Current.Request.PhysicalApplicationPath + "Application.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True";            
        }

现在我尝试将NHibernate实现到项目中

hibernate.cfg.xml此处：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>        
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle</property>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>    
    <property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property>  
    <property name="connection.connection_string">Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\1\Desktop\Application+\Application\Application.mdf;Integrated Security=True;User Instance=True</property>    
    <property name="dialect">NHibernate.Dialect.MySQL5Dialect</property>    
    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration>

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="WrapperObjects" namespace="WrapperObjects">  
  <class name="Clients" table="Clients" lazy="false">  
    <id name="Id" column="id">
      <generator class="native"></generator>
    </id>
    <property name="Name" column="name" type="System.String"/>
    <property name="Phone" column="phone" type="System.String"/>
    <property name="Fax" column="fax" type="System.String"/>
    <property name="Email" column="email" type="System.String"/>
    <property name="Address" column="address" type="System.String"/>
    <property name="ContactPerson" column="contactPerson" type="System.String"/>    
  </class>
</hibernate-mapping>

Clients.hbm.xml此处：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>        
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle</property>

    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration>

  </class>
</hibernate-mapping>

在Configure（）方法上出现错误：关键字不受支持。参数名称：attachdbfilename

如何修复？？？）

您是否尝试了没有

用户实例的连接字符串

例如：

Server=.\SQLExpress;AttachDbFilename=c:\mydbfile.mdf;Database=dbname; Trusted_Connection=Yes;

资料来源：

要使用用户实例功能，需要在SQL Server上启用它。这是通过执行以下命令完成的：sp_configure'user instances enabled'，'1'

由于路径可能是绝对路径或相对路径，您也可以尝试：

Data Source=.\SQLEXPRESS;AttachDbFilename=Application.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True

或

您正在NH配置中将MySqlDataDriver用作connection.driver_类。改为将其设置为NHibernate.Driver.SqlClientDriver

同样，将方言设置为NHibernate.dialogue.mssql2008dialogue

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>        
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle</property>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>    
    <property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property>  
    <property name="connection.connection_string">Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\1\Desktop\Application+\Application\Application.mdf;Integrated Security=True;User Instance=True</property>    
    <property name="dialect">NHibernate.Dialect.MySQL5Dialect</property>    
    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration>

NHibernate.ByteCode.Castle.ProxyFactory，NHibernate.ByteCode.Castle
NHibernate.Connection.DriverConnectionProvider
NHibernate.Driver.MySqlDataDriver
数据源=。\SQLEXPRESS；AttachDbFilename=C:\Users\1\Desktop\Application+\Application\Application.mdf；综合安全=真实；用户实例=True
NHibernate.dialogue.mysql5dialogue
真的

请注意，您正在使用NHibernate.Driver.MySqlDataDriver_类和NHibernate.dialogue.mysql5dialogue方言，需要将其更改为：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>        
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,NHibernate.ByteCode.Castle</property>
    <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>    
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>  
    <property name="connection.connection_string">Data Source=.\SQLEXPRESS;AttachDbFilename=C:\Users\1\Desktop\Application+\Application\Application.mdf;Integrated Security=True;User Instance=True</property>    
    <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property> 
    <property name="show_sql">true</property>
  </session-factory>
</hibernate-configuration>


NHibernate.ByteCode.Castle.ProxyFactory，NHibernate.ByteCode.Castle
NHibernate.Connection.DriverConnectionProvider
NHibernate.Driver.SqlClientDriver
数据源=。\SQLEXPRESS；AttachDbFilename=C:\Users\1\Desktop\Application+\Application\Application.mdf；综合安全=真实；用户实例=True
NHibernate.dialogue.mssql2008dialogue
真的

我假设您使用的是MSSQL 2008，如果您使用的是2005，请更改为NHibernate.dialogue.mssql2005dialogue


<?xml version="1.0" encoding="utf-8"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
  <session-factory>
