What does who mean ? Is this a response to an answer, or an article ?

You should consider reading some basic books on C#, because it's clear you don't really understand it well enough to be working in it. ds is a DataSet, as you can see. It has a Tables property. It is an array. The first table in the array has an index of 0. ds.Tables[0] returns the first table in the dataset.

Solution 2

Get familiar with the concept of a Dataset.
Essentially, a dataset is a collection of datatable objects (each of which could correspond to a table in the database).

When you say ds.tables[0], you are accessing the first table in the dataset.
You are then assigning it to the datasource of the GridView.
