是否可以使用实体框架插入多个子记录？

Question

Using entity framework. Is it possible to insert multiple child records. At the moment I am iterating through a list and adding to entity object, but only one/the last object is saved to the database. Should I just create a sproc, or is this possible with EF? eg

            //dc = datacontext
            var fileList = Session["FileNames"];
            string[] sA = fileList.ToString().Split('|');
            for (int i = 0; i < sA.Count(); i++)
            {                  
                wcc.ID = id; //which has been supplied through a previous 
          //dc.SaveChanges
                wcc.FileName = sA[i];
                dc.AddTotbObject(wcc);                   
            }
            dc.SaveChanges();
            dc.Dispose();

You're only ever adding a single instance. You'll need to do something along these lines within your loop:

wcc = new tbObject();
wcc.ID = id;
wcc.FileName = sA[i];
dc.AddTotbObject(wcc);
