Deserialize placeOrders json response?

[doctormike]

I'm struggling to create classes enabling me to deserialize the json response to placeOrders. I would use the development teams classes from their example app (which work) but these are related to each other in intuitively convoluted ways at my skill level, and are therefore of limited value for ongoing development. A typical json response is:

[{"jsonrpc":"2.0","result":{"status":"SUCCESS","mar ketId":"1.115796712","instructionReports":[{"status":"SUCCESS","instruction":{"selectionId":8 443714,"handicap":0.0,"limitOrder":{"size":2.0,"pr ice":1.01,"persistenceType":"LAPSE"},"orderType":" LIMIT","side":"LAY"},"betId":"42088480817","placed Date":"2014-10-07T07:17:48.000Z","averagePriceMatched":0.0,"sizeM atched":0.0}]},"id":1}]

I've created classes which I thought were consistent with this response but am making mistake(s) somewhere in specifying name/value pairs, as they fail to deserialize. Has anyone created appropriate classes they would be prepared to share (ideally in Visual Basic but C# would be OK).
With regards

Does this help?

interesting link there, ty for posting
found two similar ones which output VB.net as well

Json generators

Many thanks both. These are excellent tools & have enabled me to create the appropriate classes to match the response. However, deserialization of the json object still fails. I'm reproducing request, response, classes, and my attempt to deserialize below. Thank you in advance for your patience and any help you can offer!

' DESERIALIZATION CODE
placebetResponse = CreateRequest(strKey, strSessTok, strRequest)
Dim makebet As String
makebet = placebetResponse.ToString
Dim objJson = Newtonsoft.Json.JsonConvert.DeserializeObject(Of RootObject)(makebet)

Any advice on this would be greatly appreciated!

Found answer

I've managed to sort this out. Because the json response string is wrapped in square brackets it's interpreted as an array/list instead of a single object. All I had to do was change the deserialization code line to:

Dim objJson = Newtonsoft.Json.JsonConvert.DeserializeObject(Of List(Of RootObject))(makebet)

Many thanks for your help all the same. The json decoders are really useful.

With regards

Glad you got it sorted.

Interestingly, I never get a response that is wrapped in square brackets, so I wonder where they are coming from?

[doctormike]

Square brackets

Thanks, betdynamics. Square brackets in the response may be a consequence of something I'm doing in my code - if I find out why it occurs I'll be sure to let you know!

Square brackets wrapper again

Hi betdynamics, I've just looked at the sample json response for placeOrders in API-NG Reference guide - 28th July.pdf & it also includes square brackets. Their sample request is also wrapped in square brackets, and this is what governed my json request (see earlier post on this thread for my original request spec). I’ve now tried the request without square brackets & the response returns without them, deserializing with my initial code. In the interests of parsimony I’ll now forget about square brackets altogether (at least in this context). Thanks for the prompt!
With regards
Mike
