IEnumerable<XElement> 比较不一样

Question

I read an XML file by following two techniques.

1. By reading the entire XML using Parse XElement XElement.Parse(File.ReadAllText(xmlfile)) Note: I know I shouldn't have used this technique.
2. By using Load of XDocument XDocument.Load(xmlfile);

Then I tried creating a list of XElement by the following code snippet. To me, results look same but when I try to compare the two IEnumerable object, they aren't same.

What I am overlooking. Here is the code snippet

            // Read the xml db file.
            XElement xEle = XElement.Parse(File.ReadAllText(xmlfile));
            XDocument xDoc = XDocument.Load(xmlfile);


            List<XElement> xElementCollection = xEle.Elements("Map").ToList();
            List<XElement> xDocumentCollection = xDoc.Descendants("Map").ToList();

            bool bCompare = xElementCollection.Equals(xDocumentCollection);

bCompare results to false, however when I look at the data to both the lists. They look same.

You basically need to go through each element in both lists and compare them to each other by value using the XNode.DeepEquals method.

if (xElementCollection.Count != xDocumentCollection.Count)
{
  bCompare = false;
}
else
{
   bCompare = true;
   for (int x = 0, y = 0; 
     x < xElementCollection.Count && y < xDocumentCollection.Count; x++, y++)
   {
     if (!XNode.DeepEquals(xElementCollection[x], xDocumentCollection[y]))
       bCompare = false;
   }
}
