Serialize problem with cookie
- by cagin
Hi there,
I want use cookie in my web project. I must serialize my classes. Although my code can seralize an int or string value, it cant seralize my classes. This is my seralize and cookie code :
public static bool f_SetCookie(string _sCookieName, object _oCookieValue, DateTime _dtimeExpirationDate)
{
bool retval = true;
try
{
if (HttpContext.Current.Request[_sCookieName] != null)
{
HttpContext.Current.Request.Cookies.Remove(_sCookieName);
}
BinaryFormatter bf = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
bf.Serialize(ms, _oCookieValue);
byte[] bArr = ms.ToArray();
MemoryStream objStream = new MemoryStream();
DeflateStream objZS = new DeflateStream(objStream, CompressionMode.Compress);
objZS.Write(bArr, 0, bArr.Length);
objZS.Flush();
objZS.Close();
byte[] bytes = objStream.ToArray();
string sCookieVal = Convert.ToBase64String(bytes);
HttpCookie cook = new HttpCookie(_sCookieName);
cook.Value = sCookieVal;
cook.Expires = _dtimeExpirationDate;
HttpContext.Current.Response.Cookies.Add(cook);
}
catch
{
retval = false;
}
return retval;
}
And here is one of my classes:
[Serializable]
public class Tahlil
{
#region Props & Fields
public string M_KlinikKodu{ get; set; }
public DateTime M_AlinmaTarihi { get; set; }
private List<Test> m_Tesler;
public List<Test> M_Tesler
{
get { return m_Tesler; }
set { m_Tesler = value; }
}
#endregion
public Tahlil() {}
Tahlil(DataRow _rwTahlil){}
}
I m calling my Set Cookie method:
Tahlil t = new Tahlil();
t.M_AlinmaTarihi = DateTime.Now;
t.M_KlinikKodu = "2";
t.M_Tesler = new List<Test>();
f_SetCookie("Tahlil", t, DateTime.Now.AddDays(1));
I cant see cookie in Cookie folder and Temporary Internet Files but if i will call method like that:
f_SetCookie("TRY", 5, DateTime.Now.AddDays(1));
I can see cookie. What is the problem? I dont understand.
Thank you for your helps.
