代碼如下:
public class BsCookie
{
//操作的cookie
private HttpCookie _theCookie;
//對(duì)應(yīng)的cookie的名稱
private string _cookieName;
private bool _httpOnly = true;
/// <summary>
/// 是否只允許在服務(wù)器端訪問,默認(rèn)只允許在服務(wù)端訪問
/// </summary>
public bool HttpOnly
{
get { return _httpOnly; }
set { _httpOnly = value; }
}
private double _expireMinutes;
/// <summary>
/// Cookies有效的存放時(shí)間,以分鐘表示

public double ExpireMinutes
{
get { return _expireMinutes; }
set { _expireMinutes = value; }
}

{

}
