当我使用 WebSecurity.InitializeDatabaseConnection(parameters) 时出现错误（Npgsql.PostgresException: '42601: syntax error at or near "[" ）

Question

我可以将 WebSecurity.InitializeDatabase 与 PostgreSQL 一起使用吗？ 当我使用 WebSecurity.InitializeDatabaseConnection("PGConn", "userlogin", "user", "username", true); 我的 Web.config 文件：

我的 Glabal.asax.cs 代码是：

 using DapperExtensions; using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Optimization; using System.Web.Routing; using System.Web.Security; using WebMatrix.WebData; namespace PayrollContractual { public class MvcApplication : System.Web.HttpApplication { protected void Application_Start() { AreaRegistration.RegisterAllAreas(); FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters); RouteConfig.RegisterRoutes(RouteTable.Routes); BundleConfig.RegisterBundles(BundleTable.Bundles); InitializeAuthenticationProcess(); } private void InitializeAuthenticationProcess() { if(!WebMatrix.WebData.WebSecurity.Initialized) { WebMatrix.WebData.WebSecurity.InitializeDatabaseConnection("PGConn", "userlogin", "user", "username", true); // Error generates here. PGConn is the connection string name of Postgre Database,Compiler execute this statement as SQL server database string and appending "[" and "]" that's why generates error. But it works well if we connect it to the SQL server connection string that is SQLConn... // WebSecurity.InitializeDatabaseConnection("SQLConn", "Users", "UserId", "UserName", autoCreateTables: false); WebSecurity.CreateUserAndAccount("admin", "admin123"); if (!Roles.RoleExists("Administrator")) { Roles.CreateRole("Administrator"); } if (!Roles.RoleExists("Manager")) { Roles.CreateRole("Manager"); } if (!Roles.RoleExists("User")) { Roles.CreateRole("User"); } // WebSecurity.InitializeDatabaseConnection(connectionStringName: "PGConn", userTableName: "public].[UserLogin", userIdColumn: "user_id", userNameColumn: "user_name", autoCreateTables: true); } } } }

我需要做什么更改才能使编译器为 postgreSQL 而不是 SQL Server 语句执行此代码？ 请帮我解决这个问题。 我想现在我已经分享了所有的代码。 提前致谢。 也请参考截图。 在此处输入图像描述

默认的脚手架 ASP.NET Identity 项目包含为 SQL Server 生成的现成迁移； 试图在 PostgreSQL 上应用它们会失败。 您需要删除迁移目录并为 PostgreSQL 重新生成迁移。
