我试图在Visual Basic 2013中将反序列化的json数据插入sqlite表。但是，我在反序列化json数据时遇到了问题。Json数据结构如下-

我甚至试过

JObject

和

List（JToken的）

-

---

但是，以上这些似乎都不起作用我被困在这里超过2天，但无法确定如何反序列化此Json并插入sqlite表。

错误消息的关键部分是：

将反序列化类型更改为数组或实现类似列表的集合接口（例如ICollection、IList）的类型

这两种方法中的任何一种都适用于校正后的数据：

' get a List<T>
Dim myQAs = JsonConvert.DeserializeObject(Of List(Of JSON_Questions))(jstr)

' deser to an array:
Dim myQAs = JsonConvert.DeserializeObject(Of JSON_Questions())(jstr)

输入点后，Intellisense将显示字段，您可以选择所需内容

如果

选项\u 01

…等是选项的集合或数组，而不是一次又一次地详细说明，那么整个事情将更容易处理。

关键是：

无法将当前JSON数组（例如[1,2,3]）反序列化为类型 “quick_Maker.JSON_Questions”，因为该类型需要一个JSON对象

反序列化程序需要一个JSON对象，但您正在传递一个JSON数组。只需删除开头和结尾的方括号，代码就会开始工作

或者你也可以使用

Dim jResults As JArray = JArray.Parse(rawresp)

而不是

Dim jResults As JObject = JObject.Parse(rawresp)

希望这能有所帮助，尽管它还没有经过测试。

根据www.jsonlint.com，它不是有效的Json

“这是一个演示问题”“

有一个额外的尾随引号“为什么您使用

WebRequest.Create（URL）

而不是

HttpWebRequest.Create（URL）

？@Protoix json是在php中使用

$json=json_encode（$resultArray）；

生成的，我也在发布我的php代码。不确定是谁、什么或在哪里创建的，

”问题\文本“：“这是一个演示问题”“

无效-请注意额外的引号，并注意此时语法高亮显示是如何阻塞的。您的代码似乎正常工作，但现在我无法将变量

jd

中的列/行插入sqlite之前我可以使用

jsonQuestion.QID

等等。是的，你是对的，如果我有一系列的选择会更容易，这会更容易，但是作为一名医生，现在我不能给适当的时间来学习这些。现在它们在一个数组或列表中，所以使用

jd（0）。QID

Intellisense将引导你感谢你的耐心，我现在知道了，很抱歉还有更多问题。但最后两个问题-1我应该使用哪一个-

列表

或

数组

，因为这两个问题对我来说都很好，我不知道它们的优缺点。2（有点离题）当我将这个json输出插入sqlite时，会有更快的方法吗。目前我正在一行一行地循环。但是10公里的问题要花很多时间。谢谢。很抱歉，我真的很想知道，即使没有你的提及，我也在搜索webrequest和httpwebrequest之间的差异。。我只是把它投了更高的票，事实上这似乎是一个很好的问题。不过，我不确定这里是否还没有答案。它们之间的微妙之处并不是我的强项step

Dim jResults，因为JArray

为我工作，但这对进一步反序列化没有帮助。而与此同时，普罗泰克斯的回答对我起了作用。
