Question

Okay, so I have this LINQ to SQL situation. I have a DataContext object which links to an SQL database and I can get tables and… all of that business. This is all inside a WCF service inside IIS.

Now I connect the DataContext object when I declare it, which is at the top of the class, as follows:

DataContext dc = new DataContext([ConnectionString]);

Then, later, I have methods to do things like inserting a Client (that is a type of entity), and that looks something like this:

public void InsertClient(Client client)
{
   if(client.ClientID > 0)
      return;

   dc.Clients.InsertOnSubmit(client);

   dc.SubmitChanges();
}

The problem is basically… is there some way to test that connection? What if someone pulled a plug or something before SubmitChanges? It’s not like it returns anything, so it couldn’t tell me there was a particular error.

How would people recommend I do this?

Thanks.

Answer 1

DataContext.SubmitChanges will throw if there is an error.
