Removing rows from a dataset (i.e. achieving TOP functionality when you can't use SQL)

This might sound really obvious, but i couldn't find a better way.  Normally i would use TOP in the SQL query to limit the number of records i want to retrieve, but in my case, this value is parameterised and Access won't allow me to parameterise that value.  I tried using a DataView but TOP isn't one of it's supported functions.  So i just loop through the dataset and keep removing rows until the right number of records is reached.

int maxItems = 5;
while(ds.Tables[0].Rows.Count > MaxItems)
