使用 HttpUtility.UrlEncode() 会使程序集的命名空间“消失”？

发布于 2024-10-23 22:21:07 字数 528 浏览 6 评论 0原文

我有 2 个 C# 项目（我们称它们为 A 和 B）。项目A被编译为类库，项目B被编译为Windows应用程序。项目B添加了对项目A的引用。正常情况下，它们运行良好，没有任何问题。

我添加了一行使用 HttpUtility.UrlEncode() 来项目 A：

字符串编码 = HttpUtility.UrlEncode(queryString);

我还添加了“使用 System.Web”和对 System.Web.dll 的引用。虽然项目 A 仍然可以成功构建，但是当我构建项目 B 时，它给出了错误，说项目 A 的命名空间不存在。删除使用 HttpUtility.UrlEncode() 的行可以解决问题，但我确实需要该方法。

请帮我！提前致谢。

编辑：我发现问题：我将项目B的“目标框架”属性设置为“.net Framework 4 client profile”，这似乎不支持System.Web。只需将其更改为“.net Framework 4”即可正常工作。

I have 2 C# projects (let's call them A and B). Project A is compiled to Class library and project B is compiled to Windows Application. Project B is added a reference to project A. Normally, they run well, without any problem.

I added a line that use HttpUtility.UrlEncode() to project A:

string encoded = HttpUtility.UrlEncode(queryString);

and I also added 'using System.Web' and a reference to System.Web.dll. While project A still be built successfully, when I build project B, it gave me errors said that the namespace of project A does not exist. Removing the line that use HttpUtility.UrlEncode() solve the problem, but I really need that method.

Please help me! Thanks in advance.

Edit: I've found the problem: I set the "target framework" property of project B as ".net framework 4 client profile", which seems not support System.Web. Just change it to ".net framework 4" and it works fine.
