How to Serialize CookieContainer in wp7 applications? - serialization

Question

I tried to Serialize cookie to save it and Deserialize at next time I start my application.But the result of Deserialize is empty.What's wrong?
void SaveCookie() {
var appStorage = IsolatedStorageFile.GetUserStoreForApplication();
if (this.checkBox_save_passowrd.IsChecked == true)
{
CookieContainer cc = SEC_Services.Httprequest.cookie;
string fileName = "usercookie.xml";
using (var file = appStorage.OpenFile(fileName, System.IO.FileMode.OpenOrCreate, System.IO.FileAccess.Write))
{
using (var writer = new StreamWriter(file))
{
System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(CookieContainer));
xs.Serialize(writer, cc);
writer.Close();
}
}
}
else {
if (appStorage.FileExists("usercookie.xml"))
{
appStorage.DeleteFile("usercookie.xml");
}
}
}
void ReadCookie() {
var appStorage = IsolatedStorageFile.GetUserStoreForApplication();
if (appStorage.FileExists("usercookie.xml"))
{
using (System.IO.StreamReader reader = new StreamReader(appStorage.OpenFile("usercookie.xml", FileMode.Open)))
{
System.Xml.Serialization.XmlSerializer xs = new System.Xml.Serialization.XmlSerializer(typeof(CookieContainer));
CookieContainer obj = (CookieContainer)xs.Deserialize(reader);
reader.Close();
SEC_Services.Httprequest.cookie = obj;
if (obj.Count != 0) {
NavigationService.Navigate(new Uri("/PanoramaPage.xaml", UriKind.Relative));
}
}
}
}
I also found this simple
C#: Writing a CookieContainer to Disk and Loading Back In For Use
shows that CookieContainer could be Serialize.But there is no SoapFormatter in wp7 library

Answer 1

IsolatedStorageSettings.ApplicationSettings["index"] = yourcookie;
So you don't need to serialize it.
I'm using it in a project

Answer 2

As the question is "How to Serialize CookieContainer" and the accepted answer doesn't really answer this. This is how to do it with serialization:
Write to disk:
public static void WriteCookiesToDisk(string file, CookieContainer cookieJar)
{
using(Stream stream = File.Create(file))
{
try {
Console.Out.Write("Writing cookies to disk... ");
BinaryFormatter formatter = new BinaryFormatter();
formatter.Serialize(stream, cookieJar);
Console.Out.WriteLine("Done.");
} catch(Exception e) {
Console.Out.WriteLine("Problem writing cookies to disk: " + e.GetType());
}
}
}
Read from disk:
public static CookieContainer ReadCookiesFromDisk(string file)
{
try {
using(Stream stream = File.Open(file, FileMode.Open))
{
Console.Out.Write("Reading cookies from disk... ");
BinaryFormatter formatter = new BinaryFormatter();
Console.Out.WriteLine("Done.");
return (CookieContainer)formatter.Deserialize(stream);
}
} catch(Exception e) {
Console.Out.WriteLine("Problem reading cookies from disk: " + e.GetType());
return new CookieContainer();
}
}
