Question

How can I insert data into my database using Entity Framework ?

I’m trying this code bellow, but, in the method AddObject I have to pass 2 parameter:

• string entitySetName
• object entity

What is the entitySetName ?
The object entity is my model ?

EntityNetimoveis.San2011Entities db = new EntityNetimoveis.San2011Entities();
Model.Gerenciar.UsuarioCurso us = new Model.Gerenciar.UsuarioCurso();

public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/plain";
try
    {
        us.Usuario_Id = Convert.ToInt32(context.Request["id"]);
        db.San_UsuarioCurso.Context.AddObject(us);
        db.SaveChanges();
        context.Response.Write("ok");
    }
    catch (Exception e)
    {
        context.Response.Write("");            
    }            
}

Answer 1

It’s the name of your ObjectSet, in your case San_UsuarioCurso.

You’re going back and forth in your references however.

In db.San_UsuarioCurso.Context. You’re referencing your context (db) and then going to your objectset (San_UsuarioCurso) and then going back to your context (Context).

You can add directly to the object set like this, and not have to define the name of the entity set:

db.San_UsuarioCurso.AddObject(us);

Or if you want to use your function this should work as well:

db.San_UsuarioCurso.Context.AddObject("San_UsuarioCurso", us)
