Extracting column names from a DataView

I found an answer here that uses the DataView.Table property to get the column names.  This is valid if all of the columns are used in the DataView.  However, I have DataView instances that do not always show all of the columns.  Both the .Table property and the ToTable() method return a DataTable with ALL of the columns of the underlying table.  Is there a way to extract the column names from the DataView itself so that I can only show those that pertain to the DataView?  Is there some way to isolate that information?

try with the following:
Extract a row from the dataview, any.
this DataRow object has a DataTable property
Look at the components of this datatable

that is:

foreach (DataColumn col in yourview.Rows[0].DataTable.Columns)
{
        string name = col.Name
}
0

Actually the correct way to get there is myView[0].Row.Table.Columns.  But it is a moot point.  I misinterpretted the data that was bweing sent to my part of the application.  I was under the impression that the displayed data (in a grid in another section of the app) showed ALL of the data in the DataView that my Excel export function received.  Some of the fields are not displayed and the information I am extracting from the underlying table is correct.  Thanks to those who put some brain on this one, but my question was bad to begin with.
