问题描述

我试图用WebClient的工作，但它给我的错误，所以我在几个论坛上检查（包括这一次），并在那里他们告诉把

I am trying to work with WebClient but it is giving me errors so I check in several forums (included this one) and they where telling to put

在该文件的顶部：

using System.Net 

和之后，我想使用Web客户端：

And after where I want use the WebClient:

 WebClient webClient = new WebClient();
 webClient.DownloadFile ("http://mysite.com/myfile.txt", @"c:\myfile.txt");

和我得到这个错误：

类型或命名空间名称'的WebClient'找不到（是否缺少using指令或程序集引用？）

The type or namespace name 'WebClient' could not be found (are you missing a using directive or an assembly reference?)

在其他论坛我刚写的代码上面似乎是解决办法，但不是为我工作。

In the other forums the code that I just wrote above seems to be the solution but is not working for me.

推荐答案

鉴于你的标签，这听起来像你可能会构建Windows商店应用 - 在这种情况下，你需要使用<一个HREF =http://msdn.microsoft.com/en-us/library/system.net.http.httpclient.aspx> 的HttpClient 代替 Web客户端。

Given your tags, it sounds like you may be building a Windows Store app - in which case you need to use HttpClient instead of WebClient.
