Returning from the scope of 'using'?

Question

I have a code that looks like this:

using (DBDataContext dc = new DBDataContext(ConnectionString)) { Main main = new Main { ClientTime = clientTime }; dc.Mains.InsertOnSubmit(main); dc.SubmitChanges(); return main.ID; } 

If I return from "use", will the cleanup still be used?

Answer 1

Yes, and this is one of the big advantages of using it.

Answer 2

Yes. This is really the equivalent of a try/finally - and finally blocks are executed, however the try block is completed, whether through an exception, the return statement or simply reaches the end of the block.

Answer 3

Yes it will.

Answer 4

Yes, all instances of objects that were initialized by the resource collection part in the using statement will automatically call the Dispose() method.

Answer 5

Yes, he will be cleansed. I see this as a failed C # attempt to support the Resource Initialization pattern.
