使用System.Data.OracleClient配置Fluent NHibernate

本文关键字：Fluent NHibernate 配置 OracleClient System Data 使用 | 更新日期: 2023-09-27 18:21:29

我正在尝试使用System.Data.OracleClient，而不是带有Fluent Nhibernate的Oracle.DataAccess。据我所知，为了实现这一点，我应该将我的驱动程序从OracleDataClientDriver更改为OracleClientDriver。我已经按照下面的方式配置了它，但我得到了一个错误，看起来它仍在尝试使用OracleDataClientDriver。我做错了什么？

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

这是一个错误，它仍在寻找Oracle.DataAccess，我正试图摆脱它。

使用System.Data.OracleClient配置Fluent NHibernate

使用OracleClientConfiguration和OracleClientDriver而不是OracleDataClientConfiguration和OracleDataClientDriver

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