I am creating a web blog where i will store xml files in a folder called entries, the page that will display the xml files i named as hotelweblog.aspx, and the page that will enter the data to create new xml files in the entries folder i named as Edit.aspx. I can create new xml files with the edit page but when displaying in the hotelweblog page it returns the below error.

FileStream file = new FileStream(filepath, FileMode.Open);
XmlSerializer serializer = new XmlSerializer(typeof(Entry));
Entry newEntry = (Entry)serializer.Deserialize(file);
file.Close();
newEntry.Timestamp = new FileInfo(filepath).LastWriteTime;
newEntry.Filename = filename;
return newEntry;
}
public static Entry[] LoadAllEntries()
{
DirectoryInfo entryFolder = new DirectoryInfo(EntryFilePath);
FileInfo[] files = entryFolder.GetFiles();
Entry[] entries = new Entry[files.Length];
int index = files.Length -1;
foreach(FileInfo file in files)
