Question

I have a datatable with 17 columns and a bunch of data.

I wnat a datatable with only 6 of the columns and the data for those 6 columns.

So I need a subset of the original datatable.

How do I loop through the original datatable with 17 columns and end up with a datatable with only the 6 columns I want with the corresponding data for those 6 columns?

Answer 1

Without knowing more about how generic this needs to be its really just…

foreach (DataRow dr in dt.Rows)
{
  newDt.Rows.Add(dr["col1"],dr["col5"],etc);
}
