使用JsonConvert.Deserialize时，变量不显示任何内容

Question

使用JsonConvert.DeserializeObject时，变量显示“无”的问题。我搜寻了其他论坛，每个人似乎都建议使用下面的代码片段，但是每次我实现并测试这些值时，显示为“无”。谁能指出我正在导致此问题的正确方向？

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

类结构如下。修剪以适合，省略了一些类型和数据。

Answer 1

您正在尝试将JSON直接反序列化为Workers.Person。由于您的JSON以Workers.Worker数组开头，因此无法正确反序列化。您应按以下步骤修改反序列化

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

然后，您可以浏览工作人员，因为他们将存储在Workers.Worker类型的数组中

Dim worker = workers[0]

可以通过以下方式访问person属性

Dim person = worker.person
