I have a dataset that I need to write to a text file out on my server.

The text file will not exist and will need to have the current datetime timestamp in the name.  So, essentially,  I pull data from sql and create a series of datasets.  I need to output the datasets to text files that look like the following.


Any and all information is so greatly appreciated...

You can output the a dataset's contents in XML format like this:

Dim strm As New IO.StreamWriter("C:\dataset1_" & Now.ToString("MM-dd-yyyy_HHmmtt") & ".txt", False, System.Text.Encoding.Unicode)

Im already doing this in xml and it is not a feasible solution...

The project requires that the files get output directly to pipe delimited text files...

In that case:

Dim strRow As String
Dim i As Integer
Dim strm As New IO.StreamWriter("C:\dataset1_" & Now.ToString("MM-dd-yyyy_HHmmtt") & ".txt", False, System.Text.Encoding.Unicode)

For Each dt As DataTable In ds.Tables
      For Each dr As DataRow In dt.Rows
            strRow = Nothing
            For Each col As DataColumn In dt.Columns
                  strRow &= dr(col) & "|"
            strRow = strRow.Remove(strRow.Length - 1, 1)
