用于数据库词典的ASP.NET通用控制器（使用实体框架）

Question

I've got some models that only have two fields: Id and Name. All this models inherit from IDbDictionary interface.

My goal is to make "universal" controller for CRUD operations for this models. My problem is how to (using EF) modify database table by name. For example, there is method

    [HttpPost]
    public ActionResult Create(IDbDictionary newRecord, string collectionName)
    {
        if (ModelState.IsValid)
        {
            db.<collectionName>.Add(newRecord);
            db.SaveChanges();
            return View("Success");
        }

        return View("Create", newRecord);
    }

Is there a way to do it the way I described? I thought about reflection, but I've no idea how to do this.

Usually you would have a Service that would handle your generic database operations which you can call from all your methods. Example:

public class DataService
{
    public readonly ApplicationDbContext dbContext;

    public DataService(ApplicationDbContext dbContext)
    {
        this.dbContext = dbContext;
    }

    public void Create<TEntity>(TEntity entity) where TEntity : IDbDictionary 
    {
        this.dbContext.Set<TEntity>().Add(entity);
        this.dbContext.SaveChanges();
    }
}

Then in your method you would use:

var dataService = new DataService(this.dbContext);
dataService.Create<ClassName>(newEntity);
