How to find the count of records in a dataset?

Answer Posted / eduardo belmonte

Regarding answer # 3 : It is correct.

Regarding answer # 2 : It is not correct, remember a
dataset contains datatables, and those datatables each can
have its own amount of datarows.

So to know "all" datarows in a dataset you have to add how
many rows "each" of its component datatables may have.

Is This Answer Correct ?    6 Yes 0 No
