首页> C#>使用System.Data.OracleClient配置流利的NHibernate

我正在尝试通过Fluent Nhibernate使用System.Data.OracleClient代替Oracle.DataAccess.据我了解,为了实现这一目标,我应该将驱动程序从OracleDataClientDriver更改为OracleClientDriver.我已经按如下所示配置了它,但是出现了一个错误,看起来它仍在尝试使用OracleDataClientDriver.我究竟做错了什么？

FluentConfiguration configuration = Fluently.Configure()                
            .Database(
            OracleDataClientConfiguration.Oracle10
            .ConnectionString(x => x.FromConnectionStringWithKey(connString))
            .Provider<NHibernate.Connection.DriverConnectionProvider>()
            .Driver<NHibernate.Driver.OracleClientDriver>()            
               )

这是错误,它仍在寻找我想摆脱的Oracle.DataAccess.

[NullReferenceException: Object reference not set to an instance of an object.]

解决方法:

使用OracleClientConfiguration和OracleClientDriver代替OracleDataClientConfiguration和OracleDataClientDriver

FluentConfiguration configuration = Fluently.Configure()                
            .Database(
            OracleClientConfiguration.Oracle10
            .ConnectionString(x => x.FromConnectionStringWithKey(connString))
            .Provider<NHibernate.Connection.DriverConnectionProvider>()
            .Driver<NHibernate.Driver.OracleClientDriver>()            
               )

问题中的评论解决了我的问题.我已将此答案发布给其他人@PapaBurgundy& @Rivarolle应该得到全部的功劳.
