Code for assigning values to sessions and obtaining session values in asp.net

Asp tutorial. 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.

// Interface for session
Public interface isession {
String tostring ();
}

2. session

// 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 "";
}
}

Session assignment

Loginsession currentmanager = new loginsession ();
Currentmanager. username = "admin ";
Currentmanager. permission = "all ";
Currentmanager. sessionid = httpcontext. current. session. sessionid; <br> httpcontext. current. session [apps tutorial etting. globalsessionname] = currentmanager;
Httpcontext. current. session. timeout = 200;

Get the session Value

Public static t getglobalsessionvalue <t> (string _ propertyname)
{
Return getsessionvalue <t> (common. const. deleetting. globalsessionname, _ propertyname );
}

Public static t getsessionvalue <t> (string _ sessionname, string _ propertyname)
{
T retval = default (t );
String propertyname = _ propertyname. tolower ();

If (convert. tostring (httpcontext. current. session [_ sessionname])! = "")
{
Object sessionobject = (object) httpcontext. current. session [_ sessionname];

If (sessionobject is isession)
{
Propertyinfo [] propertyinfos = sessionobject. gettype (). getproperties ();

Foreach (var pi in propertyinfos)
{
String refname = pi. name. tolower ();
If (propertyname = refname)
{
Retval = (t) pi. getvalue (sessionobject, null );
Break;
}
}
}
}

Return retval;
}

In the program, you can obtain the value of a certain item in the session.

String _ tmpstr = utilities. getglobalsessionvalue <string> ("username ");
Int _ tmpint = utilities. getglobalsessionvalue <int> ("pagesize ");
Model. manager = utilities. getglobalsessionvalue <manager> ("managerdetail ");
