将 JSON 字符串转换为 C# 对象 [英] Convert JSON String To C# Object

问题描述

尝试将 JSON 字符串转换为 C# 中的对象.使用一个非常简单的测试用例:

Trying to convert a JSON string into an object in C#. Using a really simple test case:

JavaScriptSerializer json_serializer = new JavaScriptSerializer();
object routes_list = json_serializer.DeserializeObject("{ "test":"some data" }");

问题是 routes_list 永远不会被设置；这是一个未定义的对象.有什么想法吗?

The problem is that routes_list never gets set; it's an undefined object. Any ideas?

推荐答案

您似乎正在尝试反序列化为原始对象.您可以创建一个代表您要转换到的对象的类.这在您处理较大对象或 JSON 字符串的情况下最有用.

It looks like you're trying to deserialize to a raw object. You could create a Class that represents the object that you're converting to. This would be most useful in cases where you're dealing with larger objects or JSON Strings.

例如:

  class Test {

      String test; 

      String getTest() { return test; }
      void setTest(String test) { this.test = test; }

  }

那么你的反序列化代码将是:

Then your deserialization code would be:

   JavaScriptSerializer json_serializer = new JavaScriptSerializer();
   Test routes_list = 
          (Test)json_serializer.DeserializeObject("{ "test":"some data" }");
