How to test if a DataSet is empty?

Question

I'm modifying someone else's code where a query is performed using the following:

DataSet ds = new DataSet(); SqlDataAdapter da = new SqlDataAdapter(sqlString, sqlConn); da.Fill(ds); 

How can I tell if the DataSet is empty (i.e. no results were returned)?

Answer 1

If I understand correctly, this should work for you

if (ds.Tables[0].Rows.Count == 0) {     // }
