Question

我正在尝试使用以下代码

发布使用Web客户端从用户收到的消息

包括：

using System;
using System.Net;
using System.Threading;
using Newtonsoft.Json;

using Microsoft.Bot.Builder.Azure;
using Microsoft.Bot.Builder.Dialogs;
using Microsoft.Bot.Connector;

代码：

 URIBase = new Uri("https://somedomain.com/");
 var builder = new UriBuilder($"{UriBase}/analytics/message?");

 using (WebClient webclient = new WebClient())
 {
     //Set the encoding to UTF8
     webclient.Encoding = System.Text.Encoding.UTF8;
     webclient.Headers.Add("Content-Type", "application/json");

     var postBody = $"{{\"message\": \"{this.answer}\", \"key\": \"7F02D18E-88E7-486D-B51F-550118491CB1\"}}";

     webclient.UploadString(builder.Uri, postBody);
  }

在编译过程中，我收到以下错误：

2017-09-08T15:06:55.842 D:\home\site\wwwroot\messages\RootDialog.csx(98,17): error CS0103: The name 'URIBase' does not exist in the current context

从错误中看来它找不到WebClient和UriBase，但我认为它们在System.Net，所以我不确定发生了什么。我在其他帖子中读过使用WebClient的人，所以似乎有办法。谁能看到我做错了什么？

URIBase需要一种类型而且你有拼写错误。将这两行更改为：

var uriBase = new Uri("https://somedomain.com/");
var builder = new UriBuilder($"{uriBase}/analytics/message?");

请注意var上的uriBase，允许变量假定其已分配的类型。您也可以明确声明变量类型，如下所示：

Uri uriBase = new Uri("https://somedomain.com/");

由于这个原因，可能发生了其余的错误。

Microsoft Bot Framework C＃Web Client在当前上下文中不存在
