Question

 for (int i = 0; i < 1000; i++)
 {
      PrivateMessage privateMessage = new PrivateMessage()
      {
          id=i
      };
      dc.PrivateMessages.InsertOnSubmit(privateMessage);
      dc.SubmitChanges(); 
 }

This method is suitable for insert 1000 records?

There are better ways to do this?

Answer 1

Yeah– probably best not to do your InsertOnSubmit in a loop. Try:

List<PrivateMessage> messages = new List<PrivateMessage>();

for (int i = 0; i < 1000; i++)
{
   messages.Add(new PrivateMessage() { id=i });
}

dc.PrivateMessages.InsertAllOnSubmit(messages);
dc.SubmitChanges();
