*.ASHX file cannot access Session value solution _ Practical Tips

This example describes a workaround for *.ashx files that do not have access to session values. Share for everyone to use for reference. The specific methods are as follows:

The instance code is as follows:

<%@ WebHandler language= "C #" class= "Producthandler"%> using System; 
Using System.Web; 
Using JBTCard.Entity.CompanyEntity; 
Using JBTCard.Business.CompanyBS; 
Using System.Collections.Generic; 
Using Newtonsoft.json; 

Using System.Web.SessionState;  public class Producthandler:ihttphandler, irequiressessionstate, ireadonlysessionstate{public void ProcessRequest (HttpContext context) {String ModuleID = context. request.form["ModuleID"]. 
  ToString (); 
  String message = ""; Switch (moduleid) {case "getptypelist": ilist<producttypeidnameentity> list = Producttypebs.getptypelistid 
  Name (); 
  message = Javascriptconvert.serializeobject (list); 
  Break Case "Getcompanybyid": Int cid = Convert.ToInt32 (context.  session["CID"]); 
  Companyentity Company = Companybs.getcompanyentybyid (1); 
  Message = Javascriptconvert.serializeobject (company); 
  Break Case ' Insert ': string CoNDIS = context. request.form["Condi"]. 
  ToString (); ProductEntity model = (productentity) 

  Javascriptconvert.deserializeobject (CoNDIS, typeof (ProductEntity)); 
  BOOL B = productbs.addproduct (model); 
  if (b) {message = ' {success:true} '; else {throw new Exception ("Product add failed!") 
  "); 
  } break; } context. 
  Response.ContentType = "Text/javascript"; Context. 
  Response.Write (message); 
    public bool IsReusable {get {return false;

 } 
  } 
}

In fact, just add this sentence is good:

Using System.Web.SessionState;

I hope this article will be helpful to our ASP.net program design.
