如何在实体框架核心中的运行时上创建迁移 [英] How to Create Migration on Runtime in Entity Framework Core

问题描述

是否有任何可能的方法可以在efcore中的运行时上创建迁移.

Is there any possible way to create migration on runtime in efcore.

context.Database.Migrate();

在此代码之前，我需要一个代码，当我启动我的应用程序时，应在postgresql数据库表和ef模型之间创建有关diff的迁移.

Before this code, I need a code that, when I started my app, should create a migration about diff between postgresql database tables and ef models.

有什么办法吗?

PM> enable-migrations
PM> add-migration initial
PM> update-database

我不想使用这些.我想在运行时执行这些代码的工作.我希望我能清楚地解释自己.

I dont want to use these ones. I want to make these code's jobs on runtime. I hope I could explain myself clearly.

推荐答案

注意，您需要在调用Add-Migration之后重新编译应用程序.在应用运行时很难做到这一点.

Note, you need to re-compile the app after calling Add-Migration. It's very difficult to do this while the app is running.
