DataSet and DataTable both implement IDisposable, so, by conventional best practices, I should call their Dispose() methods.
However, from what I’ve read so far, DataSet and DataTable don’t actually have any unmanaged resources, so Dispose() doesn’t actually do much.
Plus, I can’t just use using(DataSet myDataSet...) because DataSet has a collection of DataTables.
So, to be safe, I’d need to iterate through myDataSet.Tables, dispose of each of the DataTables, then dispose of the DataSet.
So, is it worth the hassle to call Dispose() on all of my DataSets and DataTables?
Addendum:
For those of you who think that DataSet should be disposed:
In general, the pattern for disposing is to use using or try..finally, because you want to guarantee that Dispose() will be called.
However, this gets ugly real fast for a collection. For example, what do you do if one of the calls to Dispose() thrown an exception? Do you swallow it (which is “bad”) so that you can continue on to dispose the next element?
Or, do you suggest that I just call myDataSet.Dispose(), and forget about disposing the DataTables in myDataSet.Tables?
