<%@ 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
