MVC, controls, session and cookie in general processing programs, mvcsession

In Mvc:

Session:

If (! String. isNullOrEmpty (find) // sets Session ["oip"] = "Wuxi"; ViewBag. oip = Session ["oip"]; if (Session ["oip"] = null) // obtain Session ["oip"] = null; // set to null

Session. Timeout = 1; // set the expiration time

<SessionState mode = "InProc" timeout = "30"/> // 30 minutes after expiration

Cookie:

HttpCookie cookie = new HttpCookie ("oip"); cookie. expires = System. dateTime. now. addYears (1); cookie ["oipp"] = "username"; Response. cookies. add (cookie); // set
<SessionState mode = "InProc" timeout = "60"/> // set the expiration time
Cookie ["oipp"] = null;
HttpCookie cookiee = Response. Cookies. Get ("oip"); // Get
ViewBag. oip = cookiee ["oipp"];

Control:

Session ["UserInfo"] // set and obtain

Cookie: C # Calculate time difference using the timespan function http://www.blogjava.net/AndyZhang/archive/2012/05/02/377157.html

HttpCookie cookie = new HttpCookie ("MyCook"); // The Name Of The first-made Cookie and the cookie is set // DateTime dt = DateTime. now; TimeSpan ts = new TimeSpan (0, 0, 1, 0, 0); // The expiration time is 1 minute cookie. expires = dt. add (ts); // set the cookie expiration time. values. add ("userid", "userid_value"); cookie. values. add ("userid2", "userid2_value2"); Response. appendCookie (cookie );Set if (Request. Cookies ["MyCook"]! = Null) // obtain {// Response. write ("the key value of Cookie is userid:" + Request. cookies ["MyCook"] ["userid"]); // The whole line // Response. write ("the key value of Cookie is userid2" + Request. cookies ["MyCook"] ["userid2"]); Response. write (Request. cookies ["MyCook"]. value); // output all values}Get // obtain the client's Cookie object HttpCookie cok = Request. Cookies ["MyCook"]; // modify the new if (cok! = Null) {// two methods for modifying a Cookie, cok. values ["userid"] = "alter-value"; cok. values. set ("userid", "alter-value"); // Add the new content cok to the Cookie. values. set ("newid", "newValue"); Response. appendCookie (cok );}Modify and add HttpCookie cok = Request. Cookies ["MyCook"]; if (cok! = Null) {if (! CheckBox1.Checked) {cok. values. remove ("userid"); // Remove the value whose key value is userid} else {TimeSpan ts = new TimeSpan (-1, 0, 0, 0); cok. expires = DateTime. now. add (ts); // Delete the entire Cookie, as long as the expiration time is set to now} Response. appendCookie (cok );}Delete

General handler:

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 "); // set cookie ["CityID"] = HttpContext. current. server. urlEncode (cityID); // encode cookie ["CityName"] = HttpContext. current. server. urlEncode (CityName); cookie. expires = DateTime. now. addDays (10); // HttpContext. current. response. cookies. add (cookie);} else {// read the value directly. Note the encoding and decoding. Otherwise, garbled characters may occur.
Server. UrlDecode ()
}

# Used to mark a specific document LOCATION % 23% encode special characters % 25 & separate different variable value pairs % 26 + in the variable value, the space % 2B \ represents the directory path % 2F = used to connect the key and Value % 3D? Start % 3F of the query string

 

HttpCookie cookie = new HttpCookie ("Test"); // The name TimeSpan ts = new TimeSpan (0, 0, 1, 0, 0) of the First-made Cookie ); // The expiration time is 1 minute cookie. expires = DateTime. now. add (ts); // set the cookie expiration time. values. add ("userid", "123456"); cookie. values. add ("test", "THIS_IS_TEST"); context. response. appendCookie (cookie); context. response. write (context. request. cookies ["Test"]. value); // get
