Unified Session management in ASP. NET

In my actual work, ASP. the definitions and cancellation of sessions in NET are sometimes scattered. When everyone in the Working Group defines sessions differently and the names are random, a Session is managed in a unified manner to facilitate the standardization of sessions.

The Code is as follows:

1. Define the interface: you only need to implement ToString.

View sourceprint? 1 // Interface for Session

2 public interface ISession {

3 string ToString ();

4}

2. Session

View sourceprint? // ManagerInfo is a class in the Model and inherits directly

// When an object is put into the Session, the object must be serializable.

[Serializable]

Public class LoginSession: ManagerInfo, ISession

{

Public LoginSession (): base ()

{

SessionID = "";

}

Public string SessionID {get; set ;}

Public override int GetHashCode ()

{

Return SessionID. GetHashCode ();

}

Public override string ToString ()

{

If (! String. IsNullOrEmpty (SessionID ))

Return SessionID;

Else

Return "";

}

}

3. Session assignment

View sourceprint? 1 LoginSession currentManager = new LoginSession ();

2 currentManager. username = "Admin ";

3 currentManager. permission = "all ";

4 currentManager. SessionID = HttpContext. Current. Session. SessionID; <BR> HttpContext. Current. Session [deleetting. GlobalSessionName] = currentManager;

5 HttpContext. Current. Session. Timeout = 200;

4. Get the Session Value

View sourceprint? 01 public static T GetGlobalSessionValue <T> (string _ propertyName)

02 {

03 return GetSessionValue <T> (Common. Const. deleetting. GlobalSessionName, _ propertyName );

04}

05

06 public static T GetSessionValue <T> (string _ sessionName, string _ propertyName)

07 {

08 T retVal = default (T );

09 string propertyName = _ propertyName. ToLower ();

10

11 if (Convert. ToString (HttpContext. Current. Session [_ sessionName])! = "")

12 {

13 object SessionObject = (object) HttpContext. Current. Session [_ sessionName];

14

15 if (SessionObject is ISession)

16 {

17 PropertyInfo [] propertyInfos = SessionObject. GetType (). GetProperties ();

18

19 foreach (var pi in propertyInfos)

20 {

21 string refName = pi. Name. ToLower ();

22 if (propertyName = refName)

23 {

24 retVal = (T) pi. GetValue (SessionObject, null );

25 break;

26}

27}

28}

29}

30

31 return retVal;

32}

5. You can obtain the value of a Session in the program as follows:

View sourceprint? String _ tmpstr = Utilities. GetGlobalSessionValue <string> ("username ");

Int _ tmpint = Utilities. GetGlobalSessionValue <int> ("pagesize ");

Model. Manager = Utilities. GetGlobalSessionValue <Manager> ("ManagerDetail ");
