添加另一个DbContext的最佳方法

public class MySecondDbContext : DbContext
{
    public MySecondDbContext(DbContextOptions<MySecondDbContext> options) : base(options)
    {
    }

    // 定义实体类的DbSet和其他配置
    public DbSet<MyEntity> MyEntities { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        // 配置实体类的映射关系等
    }
}

services.AddDbContext<MySecondDbContext>(options =>
    options.UseSqlServer(Configuration.GetConnectionString("SecondDbConnection")));

public class MyController : Controller
{
    private readonly MySecondDbContext _secondDbContext;

    public MyController(MySecondDbContext secondDbContext)
    {
        _secondDbContext = secondDbContext;
    }

    // 在控制器中使用第二个DbContext进行数据操作
}
