How do you equate:

C#

db.Data1 = del.thistable;???

This works:

C#

del.thistable= db.Data1.ToList();

How do you do the reverse?

XML

public class HomeController : Controller
{
    private testContext db = new testContext();
    private DeleteModel del = new DeleteModel();
    public ActionResult Delete(int testID)
    {
        del.thistable= db.Data1.ToList();
        del.thistable.Remove(del.thistable.SingleOrDefault(o => o.testID == testID));
        db.Data1 = del.thistable;???
    }
}

Class1.cs

XML

public class Table1
   {
       [Key]
       public int testID { get; set; }
       public string datetime { get; set; }
       public string col1 { get; set; }
       public string col2 { get; set; }
       public string col3 { get; set; }
   }
   public class DeleteModel
   {
       public string errorcode { get; set; }
       public List<Table1> thistable { get; set; }
   }
   public class testContext : DbContext
   {
       public DbSet<Table1> Data1 { get; set; }
   }

Solution 1

Try replacing your Delete method with the following and you should be good to go.

C#

public ActionResult Delete(int testId)
   {
            var table1 = new Table1() { testID = testId };
           db.Entry(table1).State=EntityState.Deleted;

              db.SaveChanges();
