Dataset copy() memory leak

Question

Hi

I have an application that needs to frequently backup a dataset and revert to that backup if the users decides to cancel an action.

There is a global dataset created at the top of the class:

DataSet database = null;

Every time a form is opened the main dataset is copied into the created variable:

database = AppModel.Instance.Data.Data.Copy();

The problem is that every time the form is opened the memory increases by quite a lot and is never released.

I've tried disposing the database variable after it's been used but the memory still remains high - This has left me to believe that the DataSet.Copy() method allocates to new memory every time.

Any suggestions to free up the memory would be greatly appreciated.

Regards,

Jason
