Question

I am wondering how to use the linq retrieving an XML which looks exactly like this?

 <int xmlns="http://schemas.microsoft.com/2003/10/Serialization/">20</int>

Should I use the linq? I don’t know how to retrieve this number.

This is the code I try to use, I’m stuck after the select. Can someone help me?

public void wc_DownloadTopFolder(object sender, DownloadStringCompletedEventArgs e)
    {
        if (e.Error == null)
        {
            try
            {
                // Retrieving the Top Folders
                XDocument xdoc = XDocument.Parse(e.Result, LoadOptions.None);
                int i = from query in xdoc.Descendants("int")
                        select new int
                            {

                            };
            }

You can use this:

var number = int.Parse(xdoc.Root.Value);

If you are not sure the returned value is a number, you should use this:

int number;
if(int.TryParse(xdoc.Root.Value, out number))
{
    // you got a number
}
