Problem in reading XML

Hello Guys can you help me solving my problem in reading xml. I'm just new in xml. Here's the sample xml.

<Org>
    <Org ID="1">
        <OrgNum>1</OrgNum>
        <OrgName>sample1</OrgName>
    </Org>
    <Org 开发者_Python百科ID="2">
        <OrgNum>2</OrgNum>
        <OrgName>sample2</OrgName>
    </Org>
</Org>

I want to get only the OrgName with an Org ID = 2. Here's my sample code but it's read all the text. Help me plz..Tnx

string xml = Application.StartupPath + "\\OrgName.xml";
XmlDocument xmlDoc = new XmlDocument();
if (System.IO.File.Exists(xml))
{
    XmlTextReader textReader = new XmlTextReader(xml);
    textReader.Read();
    while (textReader.Read())
    {
        XmlNodeType nType = textReader.NodeType;
        if (nType == XmlNodeType.Text)
        {
            MessageBox.Show(textReader.Value);
        }
    }
}

A simple way to do it with linq:

 var doc = XDocument.Load(Application.StartupPath + "\\OrgName.xml");
 var result = doc.Root.Elements("Org").Where(x=>x.Attribute("id").ToString()=="2");

Maybe your life gets a lot easier if you start using tools like xdocument, xmldocument and xpath

If you want to use the classic .net Xml object model, you could try this:

    string xml = Application.StartupPath + "\\OrgName.xml";
    XmlDocument xmlDoc = new XmlDocument();
    if (System.IO.File.Exists(xml))
    {
       xmlDoc.Load(xml);
       XmlElement root = xmlDoc.DocumentElement;
       string orgName = root.SelectSingleNode(@"descendant::Org[@ID='1']/OrgName").InnerText;
       MessageBox.Show(orgName);
    }
