c# - "The name does not exist in the current context"

我收到以下错误；
当前上下文中不存在名称“请求”

using System;
using System.Web;
using System.Web.UI;
using System.Collections.ObjectModel;
using System.Collections.Specialized;
using Microsoft.Exchange.WebServices.Data;

namespace Exchange101
{
    // This sample is for demonstration purposes only. Before you run this sample, make sure that the code meets the coding requirements of your organization.
    class Ex15_CreateMeetingOnBehalfOfPrinciple_CS
    {
        static ExchangeService service = Service.ConnectToService(UserDataFromConsole.GetUserData(), new TraceListener());
        protected void Page_Load(object sender, EventArgs e)
        {
            var request = HttpContext.Current.Request.QueryString["source"];
            HttpRequest q = Request;
            NameValueCollection n = q.QueryString;
            if (n.HasKeys())
            {
                string k = n.GetKey(0);
                if (k == "one")
                {
                    string v = n.Get(0);
                }
                if (k == "two")
                {
                    string v = n.Get(0);
                }
            }
        }

我是一个绝对的新手并且已经研究过这个错误，但是对于我可能缺少哪个程序集作为引用感到困惑。

最佳答案

问题可能在这里

 var request = HttpContext.Current.Request.QueryString["source"];
 HttpRequest q = Request;

你的变量名是 request bt 你正在使用 Request

将此更改为

 var request = HttpContext.Current.Request.QueryString["source"];
 HttpRequest q = request;

这将解决您的问题
