问题描述
我正在尝试使用.NET的System.Web.Script.Serialization.JavaScriptSerializer在MacOS上的MonoDevelop中将JSON文件读入字典中.
I'm trying to use .NET's System.Web.Script.Serialization.JavaScriptSerializer to read a JSON file into a Dictionary in Unity with MonoDevelop on MacOS.
到目前为止，我已经在MonoDevelop中添加了System.Web.Extensions程序集，这使得它可以很好地构建"Assembly-CSharp"项目.
So far I've added the System.Web.Extensions assembly to MonoDevelop which makes it build the "Assembly-CSharp" project fine.
但是当我回到Unity时，它仍然显示错误:错误CS0234:名称空间"System"中不存在类型或名称空间名称"Web".您是否缺少程序集参考?
But when I go back to Unity, it still shows the error: error CS0234: The type or namespace name `Web' does not exist in the namespace `System'. Are you missing an assembly reference?
然后我在网上阅读到将DLL添加到资产文件夹中的任何位置都可以，因此我在MonoDevelop的路径中找到文件System.Web.Extensions.dll的某些版本，它们位于:/Applications/Unity/MonoDevelop.app/Contents/Frameworks/Mono.framework/Versions/2.10.2/lib/mono/gac/System.Web.Extensions
Then I read on the web that adding the DLL anywhere into the assets folder would do, so I found some versions of the file System.Web.Extensions.dll inside MonoDevelop's path, they are in: /Applications/Unity/MonoDevelop.app/Contents/Frameworks/Mono.framework/Versions/2.10.2/lib/mono/gac/System.Web.Extensions
有3个文件夹，其文件版本不同:1.0.61025.0__31bf3856ad364e35，3.5.0.0__31bf3856ad364e35和4.0.0.0__31bf3856ad364e35
There are 3 folders with different versions of the file: 1.0.61025.0__31bf3856ad364e35, 3.5.0.0__31bf3856ad364e35 and 4.0.0.0__31bf3856ad364e35
尝试了所有这些方法，但均无效果，Unity给出此错误:
Tried all of them, but none works, Unity gives this error:
Internal compiler error. See the console log for more information. output was:
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies.

那么，现在怎么办?
推荐答案
Unity使用了不支持.NET 4的旧版Mono.我相信，由于System，他们也删除了System.Web.dll以使其精简. Web主要包含ASP.NET，它与游戏开发人员并没有真正的联系.
Unity uses an old version of Mono that does not support .NET 4. I believe they also remove System.Web.dll to slim it down, since System.Web mostly contains ASP.NET which isn't really relevant to game developers.
您也许可以复制Mono的dll，但是请确保使用System.Web.dll的v2.0和System.Web.Extensions.dll的v3.5.
You might be able to copy over Mono's dlls, however make sure you use v2.0 of System.Web.dll and v3.5 of System.Web.Extensions.dll.
或者，您可以尝试JSON.NET.
Alternatively you might try JSON.NET.
