本文翻译自：[Cannot find JavaScriptSerializer in .Net 4.0][]

*This is how to get JavaScriptSerializer available in your application, targetting `.NET 4.0` (full)* **这是如何在您的应用程序中使用JavaScriptSerializer，目标是`.NET 4.0` （完整版）**

using System.Web.Script.Serialization;

*This should allow you to create a new `JavaScriptSerializer` object!* **这应该允许您创建一个新的`JavaScriptSerializer`对象！**

*You have to add the reference to the project.* **您必须添加对项目的引用。**

*In Assemblies, there is a System.Web.Extensions Add that.* **在Assemblies中，有一个System.Web.Extensions添加它。**

*Once that is done put:* **一旦完成，就把：**

using System.Web;
        using System.Web.Script;
        using System.Web.Script.Serialization;

*That worked for me.* **这对我有用。**

1.  *Right click `References` and do `Add Reference` , then from `Assemblies->Framework` select `System.Web.Extensions` .* **右键单击`References`并执行`Add Reference` ，然后从`Assemblies->Framework`选择`System.Web.Extensions` 。**
2.  *Now you should be able to add the following to your class file:* **现在您应该能够将以下内容添加到您的类文件中：**

using System.Web.Script.Serialization;

*For those who seem to be following the answers above but still have the problem (eg, see the first comment on the poster's question):* **对于那些似乎遵循上述答案但仍有问题的人（例如，请参阅海报问题的第一条评论）：**

*You are probably working in a solution with many projects.* **您可能正在使用许多项目的解决方案。** *The project you appear to be working in references other projects, but you are actually modifying a file from one of the other projects.* **您似乎正在使用的项目引用其他项目，但实际上您正在修改其他项目之一的文件。** *For example:* **例如：**

*  *project A references `System.Web.Extensions`* **project A引用`System.Web.Extensions`**
 *  *project A references project B* **项目A参考项目B.**

*But if the file you are modifying to use `System.Web.Script.Serialization` is in project B, then you will need to add a reference to `System.Web.Extension` in project B as well.* **但是，如果要修改的文件使用`System.Web.Script.Serialization`在项目B中，那么您还需要在项目B中添加对`System.Web.Extension`的引用。**
