| | I would suggest using a List<string> to store your rows. You could also create a CLASS to hold your rows and store the rows in a List<CLASS> or a Dictionary<string, CLASS> where the key to the dictionary is the student ID. If you're into creating classes, it will make keeping … |

| | Re: Reading in XML When I use XML, I use the System.Xml.Linq namespace. It seems to be easier. [CODE] using System; using System.Collections.Generic; using System.Linq; using System.Xml.Linq; namespace DW_393489 { class Program { static void Main(string[] args) { XDocument doc = XDocument.Load("c:/science/DaniWeb/DW_393489/XMLFile1.xml"); List<XElement> lstElements = doc.Descendants("SYMBOL").ToList(); lstElements.ForEach(xe => Console.WriteLine(xe.Attribute("Code").Value)); } } } [/CODE] |
