【问题描述】：
尝试将 JSON 反序列化为数据集时，我在下面收到此错误。可能是什么问题呢？任何帮助表示赞赏。
错误：Newtonsoft.Json.JsonSerializationException：读取 DataTable 时出现意外的 JSON 令牌。预期 StartArray，得到 StartObject。路径“状态”，第 1 行，位置 11。
Dim ds As DataSet = JsonConvert.DeserializeObject(Of DataSet)(strJSON)
以下是 JSON 的示例：

【问题讨论】：
-
能否请您添加您正在使用的语言/环境？ （我想它是 VisualBasic，不是吗？）正确标记问题。谢谢。
-
是的，对不起它的 vb.net。谢谢
-
该错误表示您正在尝试反序列化为数组 (
Expected StartArray)，但输入的 JSON 字符串表示一个对象（它以{开头）。您需要先反序列化为一个对象，然后使用字段property（一个数组）来构建数据集。 -
我对vb .net不熟悉所以我不知道你是怎么做的，但是网上应该有一些资源。
