JSON.NET无法处理简单的数组反序列化? [英] JSON.NET cannot handle simple array deserialization?

问题描述

我创建了一个只有一个字段的简单类. class Test{int value;}

I created a simple class with one field. class Test{int value;}

如果我使用保留引用"功能并将其设置为全部"(即对象和数组)，那么当我简单地序列化Test对象的数组时，它将被序列化为带有特殊"$"的JSON对象. 值"成员与数组值，以及预期的"$ id"属性来保留数组引用.没关系，但是整个过程在反序列化时再次中断.

If I use the "preserve references" feature and set it to "all" (i.e. both objects and arrays), then when I simply serialize an array of Test objects, it gets serialized as a JSON object with a special "$values" member with the array values, along with the expected "$id" property to preserve the array reference. That much is fine, but once again the whole thing breaks on deserialization.

单步执行源代码，我发现仅因为对"IsReadOnlyOrFixedSize"的测试为真，所以将标志"createdFromNonDefaultConstructor"设置为true，这甚至没有任何意义，因为尽管它是一个固定大小的数组，它是从默认构造函数创建的，除非它将任何固定大小的数组构造函数视为非默认构造函数.最重要的是，它应该能够处理如此基本的内容，但会引发此错误:"Cannot preserve reference to array or readonly list, or list created from a non-default constructor".

Stepping through the source code, I discovered that simply because the test for "IsReadOnlyOrFixedSize" is true, it sets a flag "createdFromNonDefaultConstructor" to true, which doesn't even make any sense, because although it is a fixed size array, it is created from a default constructor, unless it considers any fixed size array constructor a non-default constructor. The bottom line is that it should be able to handle something so basic, and yet it throws this error: "Cannot preserve reference to array or readonly list, or list created from a non-default constructor".

如何在保留JSON.NET中所有引用的同时反序列化基本数组，而不会出现错误?

How can I deserialize a basic array while preserving all references in JSON.NET without getting an error?

推荐答案

遇到了同样的问题，我使用了List<T>而不是T[]来解决它.

Got the same issue, I used List<T> instead of T[] to fix it.
