*.ashx一般處理程序不能訪問session值的解決方法

<%@ WebHandler Language="C#" Class="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("商品添加失敗！");     } break;     }     context.Response.ContentType = "text/javascript";     context.Response.Write(message);     }     public bool IsReusable {         get {             return false;         }     } } 

問了程序人生的站長，他說：

加上這句就好了：using System.Web.SessionState;
