How do I read and parse an XML file in C#?

Answer 1

  public void ReadXmlFile()
    {
        string path = HttpContext.Current.Server.MapPath("~/App_Data"); // Finds the location of App_Data on server.
        XmlTextReader reader = new XmlTextReader(System.IO.Path.Combine(path, "XMLFile7.xml")); //Combines the location of App_Data and the file name
        while (reader.Read())
        {
            switch (reader.NodeType)
            {
                case XmlNodeType.Element:
                    break;
                case XmlNodeType.Text:
                    columnNames.Add(reader.Value);
                    break;
                case XmlNodeType.EndElement:
                    break;
            }
        }
    }

You can avoid the first statement and just specify the path name in constructor of XmlTextReader.
