实体框架核心2.0 - 逐步运行迁移

Question

在EF6中，我可以检索迁移并​​逐步运行 有没有办法在EF Core中做类似的事情？

EF 6代码

public static void RunMigration(this DbContext context, DbMigration migration, string providerName, string manifest)
{
    var prop = migration.GetType().GetProperty("Operations", BindingFlags.NonPublic | BindingFlags.Instance);
    if (prop != null)
    {
        IEnumerable<MigrationOperation> operations = prop.GetValue(migration) as IEnumerable<MigrationOperation>;
        MigrationSqlGenerator generator = (new DbMigrationsConfiguration()).GetSqlGenerator(providerName);
        var statements = generator.Generate(operations, manifest);
        foreach (MigrationStatement item in statements)
            context.Database.ExecuteSqlCommand(item.Sql);
    }
}

您可以使用DatabaseFacade类的GetMigrations扩展方法（由Database的{​​{1}}属性返回）来获取待处理迁移名称的列表。< / p>

然后，您可以获取IMigrator服务并使用Migrate方法传递每个目标迁移名称：
