Parsing xml in C#

Question

I am struggling to read this xml file as list of friends. I need the result as List of friend (List<Friend>) where Friend is

public class Friend
{
    public string UID {get;set;}
    public string Provider {get;set;}
    public string PhotoUrl {get;set;}
    public string ProfileUrl {get;set;
} 


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

Also specify which version of .NET you're using. If you're able to use LINQ to XML, it'll make your life simpler. — Jon Skeet

If you want to use XML serialization, you have two options: use the classes in the System.Xml.Serialization namespace, and create a class structure which will hold the data you need; or have a tool such as xsd.exe to generate the classes for you. Using the former you'll get a concise data model, with the latter you may get more classes than you really need (the price for auto-generation).

If you want to use xsd.exe, you'd first save your XML in a file (say "file.xml"), then run it to create the schema for the file:

xsd.exe file.xml

This will create a file called file.xsd which contains the schema for that XML. Then you run xsd.exe again to generate the classes which can be used by the XmlSerializer to consume that XML:

xsd.exe /c file.xsd

You can try something like this.

XDocument doc = XDocument.Parse(@" ... XML ... ");
Func<XElement, string, string> get = 
    (el, name) => (string)el.Element(XName.Get(name, "urn:com:gigya:api"));
var friends =
    from el in doc.Descendants(XName.Get("friend", "urn:com:gigya:api"))
    select new Friend
        {
            UID = get(el, "UID"),
            PhotoUrl = get(el, "photoURL"),
            ProfileUrl = get(el, "profileURL"),
        };
List<Friend> friendList = friends.ToList();

    public class FriendList
    {
      public List<Friend> friends;
      public FriendList()
      {
        friends= new List<Friend>();
      }
    }

public class Friend
{  
  public string UID {get;set;} 
  public string Provider {get;set;}  
  public string PhotoUrl {get;set;}   
  public string ProfileUrl {get;set;}
}

Public class ParseFriends
{
  FriendList p = new FriendList();
  public ReadFriends()
  {
    DirectoryInfo dir = new DirectoryInfo("../path to your xml file");
    FileInfo[] files = dir.GetFiles("*.*"); // read all xml file from a folder
    XmlDocument doc = new XmlDocument();

    foreach (FileInfo f in files)
            {
                Friend e = new Friend();
                doc.Load(f.FullName);
                e.UID = doc.GetElementsByTagName("UID")[0].InnerText;
                e.Provider = doc.GetElementsByTagName("Provider")[0].InnerText;
                e.PhotoUrl = doc.GetElementsByTagName("PhotoUrl")[0].InnerText;
                e.ProfileUrl = doc.GetElementsByTagName("ProfileUrl")[0].InnerText;
                p.empDetails.Add(e);
            }
            return p;
  }
}

Try this...
