How to show XML File Data into textboxes

      static void Main(string[] args)
      {
         try
         {
            // Create an XML document instance.
            
            XmlDocument doc = new XmlDocument();

            // Load the XML data from a file.
            // This code assumes that the XML file is in the same folder.
            // the /bin/debug file of your project 

            doc.Load("Q317662.xml");  

XmlNodeList list = doc.GetElementsByTagName(string name)

for each (XmlNode item in list){
txtTextBoxOfYourChoise.Text = item.innerChild.value.ToString(); 
// or what ever you want in those text boxes 
}
             

         
         }
         catch(XmlException xmlEx)   // Handle the XML exceptions here.   
         {
            Console.WriteLine("{0}", xmlEx.Message);
         }
         catch(Exception ex)         // Handle the generic exceptions here.
         {
            Console.WriteLine("{0}", ex.Message);
         }
         
      }
   }

}

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.
