Use the XDocument class.
DiscoCoder 7-Jul-15 13:15pm
I don't know how to do...and also not understanding...if i was know about it a little bit then i may not ask it here.

anyway thanks for your suggestion.

Just google for c# read xml file, or c# xdocument examples. You'll find tons.

Hello Dear,
Thank you again for your suggestion.This time your suggestion works for me.Thank you a lot. Thank you so much..

XmlDocument xmlDoc = new XmlDocument();
XmlNodeList nodeList = xmlDoc.DocumentElement.SelectNodes("/Table/Product");
string proID = "", proName = "", price="";
foreach (XmlNode node in nodeList)
proID = node.SelectSingleNode("Product_id").InnerText;
proName = node.SelectSingleNode("Product_name").InnerText;
price = node.SelectSingleNode("Product_price").InnerText;
MessageBox.Show(proID + " " + proName + " " + price);

but is there any other best way to do same thing ? if yes then pls suggest me.

If you only want a single node you can change your xpath query. Or you can also use XDocument, not XmlDocument. They are different.

You'll want to also add error handling of course in case it doesn't find the path you are expecting.

thanks again for your response.

could you give few line codes pls...if you have 1 min for me.

There are different XML parsers offered by .NET FCL. The one which allows you to skip some part of data without overhead and extract only the data you need is implemented by this class:[^].

Thank you so much for also your suggestion...
I got my solution...thanks
You are welcome, but will you accept the answer formally? This is really the best way to read a fragment of XML.

+5 I use the XMLReader on any file where I don't know what the size will be or if the file size is over a few megabytes. The solution I gave was more in reply to the user's comment to RyanDev. I think this user is still struggling with all of this based on some of the comments.
Thank you.

Good luck, call again.

XML reader ? XML Package ? I means can i get everything there ?
I don't understand what you are talking about. I gave you precise reference to what you can use.
First, your XML nodes can't start with number like what you have. Take a look at the XML Elements[^] at W3 Schools and look at the XML Naming Rules. You will need to do something like this:
<?xml version="1.0" encoding="utf-8"?>
		<Text>Hi World</Text>
		<Text>Hi World</Text>

Second, RyanDev was pointing you to use the XDocument for you to research and learn so that when someone puts code like this:
var documentRoot = XDocument.Load(@"C:\MyXmlFile.xml").Root;

var textNode = (from nodes in documentRoot.Elements("Node")
                where nodes.Element("Value").Value == "1"
                select nodes.Element("Text")).FirstOrDefault();


You would be able to understand it. The XDocument in .NET is very easy to use and understand. I recommend that you take some time to learn it. For small XML documents, it is all I use. Below are a few tutorials that should get you started.

<pre lang="xml"><!--?xml version="1.0" encoding="utf-8"?-->
<val c="AMP">

then how do i can read String AAA in Messagebox ?</pre>
virusstorm 7-Jul-15 14:44pm
Basically, you need to parse the XML document, either by using the solution I gave or by using Sergey's solution, find your node, extract the value and assign it to the text box. There are a lot of examples here, give it a try and if you are running into a new problem, post a new question.
DiscoCoder 7-Jul-15 14:57pm
thank you for your comments. you are absolutely right.

<!--?xml version="1.0" encoding="utf-8"?-->
