将用户 ASP.NET 网页表迁移到 MVC 6

Question

信息
我想通过重新开始将我的 ASP.NET 网页项目“升级”为 ASP.NET MVC 项目，它只有几页，非常适合学习。

问题
当前项目持有几个用户进行身份验证 ASP.NET 在我的数据库中创建了一些表：

• 角色
• 个人资料
• 用户
• ...

但是当我使用 MVC 项目时，我看到它为身份验证创建了不同的表：

• AspNetUserLogins
• AspNetUserRoles
• AspNetUser
• ...

问题
如何迁移我的用户或如何告诉 ASP.net 使用旧表？

Answer 1

您可能想从 MVC-Core 中的数据库优先方法开始，但它与您目前看到的有点不同，让我解释一下添加数据库的步骤：

• 安装实体框架：

运行Install-Package Microsoft.EntityFrameworkCore.SqlServer

要从现有数据库启用逆向工程，我们还需要安装几个其他软件包。

1. 运行安装包Microsoft.EntityFrameworkCore.Tools –Pre
2. 运行安装包Microsoft.EntityFrameworkCore.Design
3. 运行安装包Microsoft.EntityFrameworkCore.SqlServer.Design

现在对您的模型进行逆向工程：

• 运行以下命令从现有模型创建模型 数据库。如果您收到说明术语的错误 'Scaffold-DbContext' 未被识别为 cmdlet 的名称，则 关闭并重新打开 Visual Studio。

Scaffold-DbContext "Server=(localdb)\mssqllocaldb;Database=DataBaseName;Trusted_Connection=True;" Microsoft.EntityFrameworkCore.SqlServer -OutputDir Models

逆向工程过程基于现有数据库的架构创建实体类和派生上下文。实体类是简单的 C# 对象，代表您将要查询和保存的数据。现在您可以创建一个DbContext 类并开始使用您的数据库，至此关于数据库的问题已经结束，现在我建议您阅读有关Identity In Asp.NET Core 的内容。
