缺少System.Net.WebClient [英] Missing System.Net.WebClient

问题描述

你好

我需要在开发中使用System.Net.WebClient类，但是当我开始编写"using System.Net"时，我发现Visual Studio的IntelliSense列表中缺少类.我尝试将.NET Framework Client Profile更改为.NET Framework，也尝试 在此处添加响应式引用，但仍然没有任何类.我使用Windows 7，Visual Studio 2010和.NET Framework 4.

I needed to use System.Net.WebClient class in my development, but when I started write "using System.Net", I found a lack of classes in IntelliSense list in my Visual Studio. I tried to change .NET Framework Client Profile to .NET Framework, also I tried to add the responsive reference there, but there were no classes still. I use Windows 7, Visual Studio 2010 and .NET Framework 4.

谢谢.

推荐答案

您是否添加了对System.dll程序集的引用?

have you added reference to System.dll assembly ?
