Hi,
do you want to remove this columns from database table or from DataTable object?
in first case you have to use SMO:

in second case just split this string into array and loop through this array :
DataTable t = ...
foreach(string col in cols)
{
t.Columns.Remove(col);
}
cols
variable represents string array of column names
