<g class="gr_ gr_20 gr-alert gr_tiny gr_spell gr_inline_cards gr_run_anim ContextualSpelling multiReplace" id="20" data-gr-id="20">i</g> am having an issue converting <g class="gr_ gr_34 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="34" data-gr-id="34">json</g> to an array:

this code works:

Dim jsJson As JsonSerializer = New JsonSerializer
Dim joContent As Newtonsoft.Json.Linq.JObject = Newtonsoft.Json.Linq.JObject.Parse(ResponseFromServer)
Dim jsonResult = (Newtonsoft.Json.JsonConvert.DeserializeObject(Of Object)(ResponseFromServer))

the problem arises with

Dim jsonArrRateResponses As Newtonsoft.Json.Linq.JArray = jsonResult("rate_responses")

For Each Rate_Response As Object In jsonArrRateResponses

next

the error is: System.NullReferenceException: Object reference not set to an instance of an object

classes:

Public Class <g class="gr_ gr_85 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="85" data-gr-id="85">Rootobject</g>

thx for ur help

The data is Json being returned from GetProjsByUserIdApi, because the GetProjsByUserIdApi is getting the data from an ASP.NET WebAPI with its default data being Json. So a Json array of DtoProjects is being returned, which is deserialized in the Dtoproject type that is loaded into a List(of Dtoproject) that is a collection.

my issue is this:

<g class="gr_ gr_33 gr-alert gr_tiny gr_spell gr_inline_cards gr_run_anim ContextualSpelling multiReplace" id="33" data-gr-id="33">i</g> am getting the <g class="gr_ gr_32 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" id="32" data-gr-id="32">json</g> response and deserializing it.

Dim jsonResult = (Newtonsoft.Json.JsonConvert.DeserializeObject(Of Object)(ResponseFromServer)) 'works fine

next, i want to convert int an array:

Dim jsonArrRateResponses As Newtonsoft.Json.Linq.JArray = jsonResult("rate_responses") 'issue jsonArrRateResponses  appears to be null

For Each rate_response As Object In jsonArrRateResponses
      Dim objshipment_id As Object = rate_response("shipment_id")

You can do that yourself.  Copy the JSON.  Paste the JSON into a Visual Studio class file by clicking the Edit -> Paste Special -> Paste Json as Classes.

It seems that the Newtonsoft deserializer expects a collection type of list.  I'm not sure why it does not like the VB array syntax, C# works fine.

Please avoid to post the same question multiple times.

So you would go rarther for strongly typed classes as suggested in the other thread as well ?

hi,

i implemented the classes as you posted  - i am still haveing the same issue

Dim jsonResultRateResponse = JsonConvert.DeserializeObject(Of Object)(strResponseFromServerRateResponse)

Dim jsonArrRateResponses As Json.Linq.JArray = jsonResultRateResponse("Rate_Response")

Your goal is not clear adn your code does not make sense.

The following code populates the Rootobject object model shown above.  I pulling the data from a file, pulling the file content in a string, and deserializing to a ,NET object.

Dim ResponseFromServer As String = System.IO.File.ReadAllText("json1.json")
Dim jsonResult = (Newtonsoft.Json.JsonConvert.DeserializeObject(Of Rootobject)(ResponseFromServer))

This syntax drills into the the Rate_Response object.

Dim ratResponse As Rate_Response = jsonResult.rate_response

This syntax creates a JArray

Dim ResponseFromServer As String = System.IO.File.ReadAllText("json1.json")
Dim array As Json.Linq.JArray = New Linq.JArray(ResponseFromServer)

I just don't understand your approach the shipment_id is a property of the reate_response and the root object.  Simply use standard VB dot notation to fetch property values.

Dim ResponseFromServer As String = System.IO.File.ReadAllText("json1.json")
Dim root As Rootobject = (Newtonsoft.Json.JsonConvert.DeserializeObject(Of Rootobject)(ResponseFromServer))

Console.WriteLine(root.rate_response.shipment_id)
Console.WriteLine(root.shipment_id)

I assume your JSON source has a bug.  You'll need to fix that on your own.  I simply took the JSON you posted above and put it in a file and named it json1.json.  If you mindlessly copied my code, without putting the JSON in a file, then I would expect a null exception error.

yzidell, you need to put on your developer hat...

You are not following the example code at all... not sure what else I can do for you.

Can you explain why you keep using this syntax...

Dim jsonArrRateResponses As Newtonsoft.Json.Linq.JArray = New Linq.JArray(strResponseFromServerRateResponse)

Rather than just grabbing the data using standard .NET syntax?

I have no idea what you are trying to do...  A few posts ago you where looking for the shipping_id and I provided the code to get that value.  Now you're doing something else...

the rate_respone object contains multiple rate objects and individual child values as well

I'm not familiar with shipengine API but I'm sure you can visit there support site for assistance.  More importantly, you have the object so all you have to do is use standard "dot" notation to fetch property values.  I have no idea what properties you want.  You need to figure that out...

        Dim ResponseFromServer As String = System.IO.File.ReadAllText("json1.json")
        Dim root As Rootobject = (Newtonsoft.Json.JsonConvert.DeserializeObject(Of Rootobject)(ResponseFromServer))

        Dim rates As List(Of Rate) = root.rate_response.rates
        For Each r As Rate In rates
            Console.WriteLine("{0} - {1}", r.shipping_amount.amount, r.shipping_amount.currency)
        Next

hi

Dim rates As List(Of Rate) = root.rate_response.rates 

is generating this error:

Object reference not set to an instance of an object.

thx

Dim rates As List(Of Rate) = root.rate_response.rates 

is generating this error:

Object reference not set to an instance of an object.

It's work perfectly for me give the JSON in your post.  It's not possible to determine the source of your error given the one line of code but I suspect there is an issue with fetching the data.  Run your code through the debugger.
