Determine how many records are in a DataSet
To determine how many records are in a dataset, you can use the Count method of the Rows in a table (last line in code).
// New DataSet
DataSet dbSet = new DataSet();
// Populate DataSet with data
dbAdapt.Fill(dbSet, "issueReport");
// Determine how many records we have
labelRecordCount.Text = dbSet.Tables["issueReport"].Rows.Count.ToString();
