If you want to select the data before populating here is a good reference on advanced select statements. If you want to manipulate your data post populating your DataSet then here's how:

DataTable myTable = dataSet.Tables[0];

var myColumn = myTable.Columns["ColumnName"];

or

var myColumn = myTable.Columns[0];

To access a single field it would look something like this.

var field = myTable.Rows[0][myColumn];
