What Good way to keep some different data in Cookies in asp.net?
- by Dmitriy
Hello!
I want to keep some different data in one cookie file and write this class, and want to know - is this good? For example - user JS enable.When user open his first page on my site, i write to session his GMT time and write with this manager JS state. (GMT time is ajax request with js). And i want to keep some data in this cookie (up to 10 values). Have any advices or tips?
/// <summary>
/// CookiesSettings
/// </summary>
internal enum CookieSetting
{
IsJsEnable = 1,
}
internal class CookieSettingValue
{
public CookieSetting Type { get; set; }
public string Value { get; set; }
}
/// <summary>
/// Cookies to long time of expire
/// </summary>
internal class CookieManager
{
//User Public Settings
private const string CookieValueName = "UPSettings";
private string[] DelimeterValue = new string[1] { "#" };
//cookie daat
private List<CookieSettingValue> _data;
public CookieManager()
{
_data = LoadFromCookies();
}
#region Save and load
/// <summary>
/// Load from cookie string value
/// </summary>
private List<CookieSettingValue> LoadFromCookies()
{
if (!CookieHelper.RequestCookies.Contains(CookieValueName))
return new List<CookieSettingValue>();
_data = new List<CookieSettingValue>();
string data = CookieHelper.RequestCookies[CookieValueName].ToString();
string[] dels = data.Split(DelimeterValue, StringSplitOptions.RemoveEmptyEntries);
foreach (string delValue in dels)
{
int eqIndex = delValue.IndexOf("=");
if (eqIndex == -1)
continue;
int cookieType = ValidationHelper.GetInteger(delValue.Substring(0, eqIndex), 0);
if (!Enum.IsDefined(typeof(CookieSetting), cookieType))
continue;
CookieSettingValue value = new CookieSettingValue();
value.Type = (CookieSetting)cookieType;
value.Value = delValue.Substring(eqIndex + 1, delValue.Length - eqIndex-1);
_data.Add(value);
}
return _data;
}
public void Save()
{
CookieHelper.SetValue(CookieValueName, ToCookie(), DateTime.UtcNow.AddMonths(6));
}
#endregion
#region Get value
public bool Bool(CookieSetting type, bool defaultValue)
{
CookieSettingValue inList = _data.SingleOrDefault(x => x.Type == type);
if (inList == null)
return defaultValue;
return ValidationHelper.GetBoolean(inList.Value, defaultValue);
}
#endregion
#region Set value
public void SetValue(CookieSetting type, int value)
{
CookieSettingValue inList = _data.SingleOrDefault(x => x.Type == type);
if (inList == null)
{
inList = new CookieSettingValue();
inList.Type = type;
inList.Value = value.ToString();
_data.Add(inList);
}
else
{
inList.Value = value.ToString();
}
}
public void SetValue(CookieSetting type, bool value)
{
CookieSettingValue inList = _data.SingleOrDefault(x => x.Type == type);
if (inList == null)
{
inList = new CookieSettingValue();
inList.Type = type;
inList.Value = value.ToString();
_data.Add(inList);
}
else
{
inList.Value = value.ToString();
}
}
#endregion
#region Private methods
private string ToCookie()
{
StringBuilder sb = new StringBuilder();
for (int i = 0; i < _data.Count; i++)
{
sb.Append((int)_data[i].Type);
sb.Append("=");
sb.Append(_data[i].Value);
sb.Append(DelimeterValue[0]);
}
return sb.ToString();
}
/// <summary>
/// Cookie length in bytes. Max - 4 bytes
/// </summary>
/// <returns></returns>
private int GetLength()
{
return System.Text.Encoding.UTF8.GetByteCount(ToCookie());
}
#endregion
}
P.S. i want to keep many data in one cookies file to compress data and decrease cookies count.
