DataTable Reset method

[Coding123456]

The MSDN documentation states that the Reset method 'Resets the DataTable to its original state' Now I may be a bit paranoid here thinking there could be a few interpretations of 'original' but here goes. Does anyone know what is classified as the 'Original State'? If the datatable contained data and then the Reset method was called. Do they mean it is the state when it was declared which has the structure of the datatable object but no data, or some other state?

It's the state that the original records were in before any changes were made. It basically throws out all the changes to the dataset/datatable it's called on. So, if you have a bunch of records in a databtable, let the user makes changes, you can throw out all the changes by calling Reset. If you call the Update method on a dataadapter, it will look at all the changes that have to be made, as tracked by the datatable, and update the database with each change appropriately. Reset throws out all those changes before you can attempt to update the database.
