使用JsonConvert.Deserialize时，变量显示“无”

问题描述 投票：0回答：1

使用JsonConvert.DeserializeObject时，我遇到变量显示“无”的问题。我搜索了其他论坛，每个人似乎建议使用下面的代码snippit，但每次我实现和测试值显示为“无”。任何人都可以指出我正在做的正确方向导致这个问题吗？

Dim userid As Workers.Person = JsonConvert.DeserializeObject(Of Workers.Person)(str)

班级结构如下。修剪以适应，省略某些类型和数据。

您正在尝试将JSON直接反序列化为Workers.Person。它无法正确反序列化，因为您的JSON从Workers.Worker数组开始。您应该按如下方式修改反序列化

Dim workers = JsonConvert.DeserializeObject(Of Rootobject)(str)

然后，您可以浏览您的工作人员，因为它们将存储在Workers.Worker类型的数组中

Dim worker = workers[0]

并且可以按如下方式访问person属性

Dim person = worker.person
