If you determine whether the dataset has changed

smokingfish

In the operation, I first read the data into the dataset, then operated the datatable in the dataset, and finally submitted to the database. In the middle, I may only change a column of values ​​in a row, but as long as the changes are made, it is necessary to determine whether the changes have occurred. , Experts please give pointers, how to determine whether there has been a change.
