I need to delete a row using ado.net entity data model. Already googling about this, but i still can't find out how to do it right.
Here's my code:
else if (mode == 3)
{
LaundryEntities1 db = new LaundryEntities1();
var query = (from user in db.Users
where user.UserID == textBoxID.Text
select user).First();
db.DeleteObject(query);
db.SaveChanges();
reload();
MessageBox.Show("Succesfully delete a user");
clear();
}
You can use
LaundryEntities1 db = new LaundryEntities1();
var query = (from user in db.Users
where user.UserID == textBoxID.Text
select user).First();
db.Entry(employer).State = EntityState.Deleted
if(db.SaveChanges())
MessageBox.Show("Succesfully delete a user");
I make a public class named Session
public class session
{
public static DatabaseEntities db = new DatabaseEntities();
public static User user = null;
}
and changed my code into
Users user = (from x in session.db.Users
where x.UserID == textBoxID.Text
select x).FirstOrDefault();
session.db.Users.DeleteObject(user);
session.db.SaveChanges();
