Question

我想首先使用PowerTools对代码进行逆向工程。当我从本地MS-SQL数据库进行逆向工程时，它可以工作，但不能从Oracle DB中进行。我在输出控制台中收到以下错误：

  System.Data.ProviderIncompatibleException: The provider did not return a ProviderManifestToken string. ---> Oracle.DataAccess.Client.OracleException: ORA-1005: null password given; logon denied
   at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck)

我可以通过右键单击项目＆gt;来正常生成EF文件。添加＆gt; ADO.NET实体数据模型＆gt;从现有数据库中选择＆＃34;＆＃34;并按照向导的其余部分。我更喜欢powertools，原因有几个（主要是映射为.cs文件）。使用Oracle时为什么不能进行逆向工程？ TIA

我不确定我是否完全理解......在您尝试生成文件之前，您似乎需要检查“记住密码”框。（即使没有检查，测试也会恢复正常！）
