Mvc中：
session:
if (!string .IsNullOrEmpty(find)) //设置 Session["oip"] = "无锡"; ViewBag.oip =Session["oip"]; if (Session["oip"] == null) //获取 Session["oip"] = null; //设为null
Session.Timeout = 1; //设置过期时间
<sessionState mode="InProc" timeout="30"/> //过期30分钟
或者：
存：
Session.Timeout = 960;
Session["customerUser"] = (from c in db.C_CustomerUser where c.Mobile == mobile select c).FirstOrDefault();
取：
private HttpSessionState session = HttpContext.Current.Session;
public C_CustomerUser GetCustomers()
{
if (session["customerUser"] != null)
{
C_CustomerUser customer = session["customerUser"] as
C_CustomerUser;
return customer;
}
cookie:
HttpCookie cookie = new HttpCookie("oip"); cookie.Expires = System.DateTime.Now.AddYears(1); cookie["oipp"] = "用户名"; Response.Cookies.Add(cookie); //设置 <sessionState mode="InProc" timeout="60"/> //设置过期时间 cookie["oipp"] =null; HttpCookie cookiee = Response.Cookies.Get("oip"); //获取 ViewBag.oip = cookiee["oipp"]; 或者 HttpCookie cookie = new HttpCookie("City"); //初使化并设置Cookie的名称 //设置 TimeSpan ts = new TimeSpan(1, 0, 0, 0, 0); //过期时间为 1天 cookie.Expires = dt.Add(ts); //设置过期时间 cookie.Values.Add("CityID", strCityID); cookie.Values.Add("CityOrg", strCityOrg); cookie.Values.Add("CityName", strCityName); HttpContext.Current.Response.AppendCookie(cookie); 取： HttpCookie cityCookie = System.Web.HttpContext.Current.Request.Cookies["City"]; if (cityCookie != null) { city = cityCookie["CityID"]; }
控件中：
Session["UserInfo"] //设置和获取
参考：http://www.cnblogs.com/kevin-top/archive/2010/07/04/1770726.html
cookie: C# 计算时间差 用timespan函数http://www.blogjava.net/AndyZhang/archive/2012/05/02/377157.html
HttpCookie cookie=new HttpCookie("MyCook");//初使化并设置Cookie的名称 //设置 DateTime dt=DateTime.Now; TimeSpan ts = new TimeSpan(0, 0, 1,0,0);//过期时间为1分钟 cookie.Expires = dt.Add(ts);//设置过期时间 cookie.Values.Add("userid", "userid_value"); cookie.Values.Add("userid2","userid2_value2"); Response.AppendCookie(cookie);
if(Request.Cookies["MyCook"]!=null) //获取 { //Response.Write("Cookie中键值为userid的值:" + Request.Cookies["MyCook"]["userid"]);//整行 //Response.Write("Cookie中键值为userid2的值" + Request.Cookies["MyCook"]["userid2"]); Response.Write(Request.Cookies["MyCook"].Value);//输出全部的值 }
//获取客户端的Cookie对象 HttpCookie cok = Request.Cookies["MyCook"]; //修改 新增 if (cok != null) { //修改Cookie的两种方法 cok.Values["userid"] = "alter-value"; cok.Values.Set("userid", "alter-value"); //往Cookie里加入新的内容 cok.Values.Set("newid", "newValue"); Response.AppendCookie(cok); }
HttpCookie cok = Request.Cookies["MyCook"]; if (cok != null) { if (!CheckBox1.Checked) { cok.Values.Remove("userid");//移除键值为userid的值 } else { TimeSpan ts = new TimeSpan(-1, 0, 0, 0); cok.Expires = DateTime.Now.Add(ts);//删除整个Cookie，只要把过期时间设置为现在 } Response.AppendCookie(cok); }
一般处理程序：
session:
context.Session["ws_user"].ToString() Session["UserInfo"] = currentUser;
cookie:
HttpCookie cookie = HttpContext.Current.Request.Cookies["info"]; // cookie = null; if (cookie == null ) { cookie = new HttpCookie("Info"); //设置 cookie["CityID"] = HttpContext.Current.Server.UrlEncode(cityID); //编码 cookie["CityName"] = HttpContext.Current.Server.UrlEncode(CityName); cookie.Expires = DateTime.Now.AddDays(10);// HttpContext.Current.Response.Cookies.Add(cookie); }else{ //直接读值，注意编码 解码、不然汉字会出现乱码。
Server.UrlDecode()
}
# 用来标志特定的文档位置 %23 % 对特殊字符进行编码 %25 & 分隔不同的变量值对 %26 + 在变量值中表示空格 %2B 表示目录路径 %2F = 用来连接键和值 %3D ? 表示查询字符串的开始 %3F
HttpCookie cookie = new HttpCookie("Test");//初使化并设置Cookie的名称 TimeSpan ts = new TimeSpan(0, 0, 1, 0, 0);//过期时间为1分钟 cookie.Expires = DateTime.Now.Add(ts);//设置过期时间 cookie.Values.Add("userid", "123456"); cookie.Values.Add("test", "THIS_IS_TEST"); context.Response.AppendCookie(cookie); context.Response.Write(context.Request.Cookies["Test"].Value); //获取
