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

Question

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了这个错误但是我很困惑我可能缺少哪个程序集作为引用。

Answer 1

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

改成

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

这会解决你的问题
