[英]Nhibernate 2.1 and mysql 5 - InvalidCastException on Setup
I am trying to use NHibernate with Spring.Net und mySQL 5. However, when setting up the connection and creating the SessionFactoryObject, I get this InvalidCastException: 我正在尝试将NHibernate与Spring.Net和mySQL 5一起使用。但是,在建立连接并创建SessionFactoryObject时,出现此InvalidCastException异常:
NHibernate seems to cast MySql.Data.MySqlClient.MySqlConnection to System.Data.Common.DbConnection which causes the exception. NHibernate似乎将MySql.Data.MySqlClient.MySqlConnection转换为导致异常的System.Data.Common.DbConnection。
System.InvalidCastException wurde nicht behandelt. Message="Das Objekt des Typs \"MySql.Data.MySqlClient.MySqlConnection\" kann nicht in Typ \"System.Data.Common.DbConnection\" umgewandelt werden."

I am using the programmatically setup approach in order to get a quick NHibernate Setup. 我正在使用以编程方式进行安装的方法,以便快速进行NHibernate安装。 Here is the setup Code:
这是设置代码:
Configuration config = new Configuration(); Dictionary props = new Dictionary(); props.Add("dialect", "NHibernate.Dialect.MySQL5Dialect"); props.Add("connection.provider", "NHibernate.Connection.DriverConnectionProvider"); props.Add("connection.driver_class", "NHibernate.Driver.MySqlDataDriver"); props.Add("connection.connection_string", "Server=localhost;Database=orm_test;User ID=root;Password=password"); props.Add("proxyfactory.factory_class", "NHibernate.ByteCode.Spring.ProxyFactoryFactory, NHibernate.ByteCode.Spring"); config.AddProperties(props); config.AddFile("Person.hbm.xml"); ISessionFactory factory = config.BuildSessionFactory(); ISession session = factory.OpenSession();
Is something missing? 缺少什么吗? I downloaded the current mysql Connector from the mysql Website.
我从mysql网站下载了当前的mysql连接器。
Shame on me, I downloaded accidently a wrong mysql connector and not the latest version: http://dev.mysql.com/downloads/connector/net/6.0.html 真可惜,我意外地下载了错误的mysql连接器,而不是最新版本: http : //dev.mysql.com/downloads/connector/net/6.0.html
Sorry! 抱歉!
