如何用Newtonsoft.Json序列化VB对象生成含点字段的API请求JSON

要让你的Person类序列化后生成API要求的"member.id"字段，只需要给MemberId属性添加Newtonsoft.Json库的JsonProperty特性，显式指定对应的JSON键名即可。

修改后的Person类代码： #

Imports Newtonsoft.Json

Public Class Person
    Public first_name As String
    Public last_name As String
    <JsonProperty("member.id")>
    Public MemberId As String
End Class

序列化示例代码： #

Dim person As New Person With {
    .first_name = "john",
    .last_name = "doe",
    .MemberId = "1234"
}

Dim json As String = JsonConvert.SerializeObject(person, Formatting.Indented)

执行后生成的JSON就是API要求的格式：

{
  "first_name": "john",
  "last_name": "doe",
  "member.id": "1234"
}
