There is no "natural" string representation for a DataRow. You need to write it out in whatever format you desire, i.e., comma-separated list of values, etc. You can enumerate the columns and print their values, for instance:

foreach (DataRow row in table.Rows)
{
    bool firstCol = true;
    foreach (DataColumn col in table.Columns)
    {
        if (!firstCol) sw.Write(", ");
        sw.Write(row[col].ToString());
        firstCol = false;
    }
    sw.WriteLine();
}
