I would like to parse an XML file and save this information into object. What is the best way to do this? Please let me know.
Thank you..

I am guessing you mean you want to serialize xml into an object not just load it into an xmlDocument object, correct?CSharpAtl– CSharpAtl2009-10-08 13:42:03 +00:00Commented Oct 8, 2009 at 13:42

You could use XmlSerializer to deserialize it.
using System;
using System.IO;
using System.Xml.Serialization;
[XmlRoot("Root")]
public class MyType
{
[XmlElement("Id")]
public string Id { get; set; }
[XmlElement("Name")]
public string Name { get; set; }
}
static class Program
{
static void Main()
{
string xml = @"<Root>
<Id>1</Id>
<Name>The Name</Name>
</Root>";
MyType obj = (MyType) new XmlSerializer(typeof(MyType))
.Deserialize(new StringReader(xml));
Console.WriteLine(obj.Id);
Console.WriteLine(obj.Name);
}
};
If you are using .Net 3.5, I would suggest using LINQ-To-XML.
A simple example...
XML file
<?xml version="1.0" ?>
<People>
<Person>
<Name> ABC </Name>
<SSN> 111111 </SSN>
<Address> asdfg </Address>
</Person>
</People>
LINQ query
XDocument doc = XDocument.Load(pathToFile);
var query = from d in doc.Root.Descendants("Person")
select d;
foreach (var q in query)
{
string name = q.Element("Name").Value;
string ssn = q.Element("SSN").Value;
string address = q.Element("Address").Value;
}

- Take the schema (or an xml file) and generate a class from that with xsd.exe. The generated code will be ugly, you may need to clean it up by hand.
- Use XmlSerializer to deserialize into an instance.
The advantage of this method over others is that you get a strongly typed object (and IntelliSense working on your object). Among other things it means that the "node lookup" is faster than at other solutions (which mostly use a dictionary).
Or you might give a try to dynamic keyword of C# 4.0, it may give you a choice to avoid generating the code and just deserialize at runtime. I'm not sure about that though. That way you lose strong typing, but keep the syntax.
