问题描述
我开发了一个简单的网络应用程序，并且在未来我想将其作为多租户来实现.
I develop a simple web app and, in the future, I want to do it as multi-tenancy.
所以我想把连接字符串直接写到OnConfiguring方法中:
So I want to write the connection string straight into OnConfiguring method:
public class ApplicationContext : DbContext
{
public DbSet<User> Users { get; set; }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
optionsBuilder.UseSqlServer("connection string from appsettings.json");
base.OnConfiguring(optionsBuilder);
}
}
创业班:
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext<ApplicationContext>();
services.AddMvc();
}
如何将连接字符串从 appsettings.json 提取到 ApplicationContext 类中?
How can I extract connection string from appsettings.json into ApplicationContext class?
我不想为 ApplicationContext 类创建任何构造函数.
I wouldn't like to create any constructors for ApplicationContext class.

您可以通过 IOptions 使用 Options Pattern 但最简单的方法是在 ApplicationContext 构造函数中使用 DI ;)
You could use Options Pattern via IOptions but the easiest way is using DI in ApplicationContext constructor ;)
