how to read a xml file and also how to store the read value in string variable in asp.net

string value1;
string value2;

protected void Page_Load(object sender, EventArgs e)
{
   Read_Xmlfile();
}

public void Read_Xmlfile()
{
   XmlTextReader reader = new XmlTextReader("D:\\WebSite2008\\WebSite3Tierdemo2\\file\\myxml.xml");
   while (reader.Read())
   {
      XmlNodeType nodeType = reader.NodeType;
      switch (nodeType)
      {
         case XmlNodeType.Element:
            if (reader.HasAttributes)
            {
               for (int i = 0; i < reader.AttributeCount; i++)
               {
                  reader.MoveToAttribute(i);
                  //value2=reader.Value;
                  //Response.Write("Attribute is {0} with Value {1}: ", reader.Name, reader.Value);
               }
            }
            break;
         
         case XmlNodeType.Text:
            //Response.Write(reader.Value);
            value1 = reader.Value;
            Response.Write(value1);
            break;
      }
   }
   //Label1.Text = value1;
   //Label2.Text = value2;
}

Let me start with the end: "store… value in string variable" is something done by assigning a value to a variable. If you did not understand it, I am not sure if it make any sense to talk about XML or not. :-)

Anyway, there are at least three ways to read XML supported by standard .NET libraries. Here is my short review of them:

1. Use System.Xml.XmlDocument class. It implements DOM interface; this way is the easiest and good enough if the size if the document is not too big.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^].
2. Use the class System.Xml.XmlTextReader; this is the fastest way of reading, especially is you need to skip some data.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmlreader.aspx[^].
3. Use the class System.Xml.Linq.XDocument; this is the most adequate way similar to that of XmlDocument, supporting LINQ to XML Programming.
   See http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.aspx[^], http://msdn.microsoft.com/en-us/library/bb387063.aspx[^].
