Json转换反序列化对象错误 [英] Json convert deserialize object error

问题描述

我一直收到这个错误。



无法反序列化当前的JSON对象

I keep getting this error.

Cannot deserialize the current JSON object

Public Class Header
    Public deviceEnrollmentTransactionID As String
    Public completedOn As String
    Public orders As List(Of OrdersDetails)
    Public statusCode As String
    Public errorCode As String
    Public errorMessage As String
    Public transactionId As String


End Class

Public Class OrdersDetails
    Public Property orderNumber As String
    Public Property orderPostStatus As String
    Public Property orderPostStatusMessage As String
    Public Property deliveries As List(Of DeliveriesDetails)

End Class

Public Class DeliveriesDetails
    Public Property deliveryNumber As String
    Public Property deliveryPostStatus As String
    Public Property devices As List(Of DevicesDetails)

End Class

Public Class DevicesDetails
    Public Property deviceId As String
    Public Property devicePostStatus As String
    Public Property devicePostStatusMessage As String

End Class

Dim varses = JsonConvert.DeserializeObject(Of Header())(content)

内容

content

"{
	"deviceEnrollmentTransactionID":"5b1354db-60de-4a77-8bb2-cec0357c0cd0_1529483946450",

推荐答案

我将代码改为下面并解决问题。

I changed the code to below and solve the issue.

Dim varses As header = JsonConvert.DeserializeObject(Of header)(content)

看起来下面的语句希望转换为字符串到标题的列表/数组但字符串（内容）的格式不正确。

Look like the below statement is expecting to convert the string into list/array of header but the string (content) is not in correct format.

Dim varses = JsonConvert.DeserializeObject(Of Header())(content)

尝试用[]包装内容字符串。例如，见下面。

Try wrap the content string with []. see below for example.

Dim content = "[{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-60De-4a77-8bb2-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-06-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""xxx.""" _
        + "}]," _
    + """statusCode"":""ERROR""" _
+ "}]"
        Dim varses = JsonConvert.DeserializeObject(Of Header())(content)

转换带有多个标题的字符串。

Convert a string with multiple header.

Dim content = "[{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-xxxx-4444-yyyy-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-07-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""YYY.""" _
        + "}]," _
    + """statusCode"":""WHAT""" _
+ "},{" _
    + """deviceEnrollmentTransactionID"" : ""5b1354db-60De-4a77-8bb2-cec0357c0cd0_1529483946450""," _
    + """completedOn"":""2018-06-20T0839:14Z""," _
    + """orders"":" _
    + "[{""orderNumber"":""SO_1234"", " _
    + """orderPostStatus"":""abc""," _
        + """orderPostStatusMessage"":""xxx.""" _
        + "}]," _
    + """statusCode"":""ERROR""" _
+ "}]"
        Dim varses = JsonConvert.DeserializeObject(Of Header())(content)
