。C＃/。NET - 帮助，我只有三个班在我System.Web命名 [英] C#/.NET - Help, I have only three classes in my System.Web namespace

问题描述

我发现这个问题时，我有一个建议，使用System.Web.HttpUtility类特定的任务。

I discovered the problem when I got a suggestion to use the System.Web.HttpUtility class for a certain task.

综观文件，我应该有关于50班的System.Web，但我只有这些：

Looking at the documentation, I should have about 50 classes in System.Web, but I have only these:

AspNetHostingPermission
AspNetHostingPermissionAttribute 
AspNetHostingPermissionLevel

我做这样的假设，因为他们是展示智能感知了唯一的，我也得到构建错误尝试时使用任何其他类比这三种。

I make this assumption since they are the only ones showing up in intellisense, and I get build errors when trying to use any other classes than these three.

我使用.NET 3.5 SP1，并在参考对话框中，它说我必须对System.Web组件的2.0版本。

I'm using .NET 3.5 SP1, and in the reference dialog it says i have version 2.0 of the System.Web component.

我迷路了。可能是什么问题？

I'm lost. What could be wrong?

推荐答案

这是三个这是在系统参考。

These are the three which are in the System Reference.

让你在你的项目中加入的System.Web参考？

Have you added a reference to System.Web in your project?
