有段程序, 是控制行下的,需要用到System.Web.HttpContext.using System;
using System.Diagnostics;
using System.Threading;
using System.Reflection;
using System.Web;
using System.Runtime.Remoting.Messaging;private HttpContext _httpContext;//这行报错,Error CS0246: The type or namespace name 'HttpContext' could not be found (are you missing a using directive or an assembly reference?) 请问怎么解决?

对的，要添加System.Web 的引用。
