本文实例讲述了*.ashx文件不能访问session值的解决方法。分享给大家供大家参考之用。具体方法如下:

实例代码如下:

<%@ 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.getptypelistidname(); 
  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("商品添加失败!"); 
  } 
break; 
  } 
  context.response.contenttype = "text/javascript"; 
  context.response.write(message); 
  } 

  public bool isreusable { 
    get { 
      return false; 
    } 
  } 
}

其实只要加上这句就好了:

using system.web.sessionstate;

希望本文所述对大家的asp.net程序设计有所帮助
