Dynamically Parse Child Nodes in JSON - json.net

Question

I have a deserialized object that I want to dynamically loop through to return the related results. The response package looks like so:
{"RatingResponse":
{"Success":"true",
"Message":"",
"QuoteID":"57451",
"LoadNum":"57451",
"Rates":
{"Rate":
[
{"SCAC":"test1",
"CarrierName":"TEST1",
"TransitTime":"1",
"ServiceLevel":"D",
"TotalCost":"1,031.82",
"ThirdPartyCharge":"1,031.82",
"Accessorials":
{"Accessorial":
[
{"Code":"400",
"Cost":"1,655.55",
"Description":"Freight"
},
{"Code":"DSC",
"Cost":"-952.77",
"Description":"Discount"
},
{"Code":"FUE",
"Cost":"329.04",
"Description":"Fuel Surcharge"
}
]
},
"QuoteNumber":""
},
{"SCAC":"test2",
"CarrierName":"TEST2",
"TransitTime":"1",
"ServiceLevel":"D",
"TotalCost":"1,031.82",
"ThirdPartyCharge":"1,031.82",
"Accessorials":
{"Accessorial":
[
{"Code":"400",
"Cost":"1,655.55",
"Description":"Freight"
},
{"Code":"DSC",
"Cost":"-952.77",
"Description":"Discount"
},
{"Code":"FUE",
"Cost":"329.04",
"Description":"Fuel Surcharge"
}
]
},
"QuoteNumber":""
}
]
},
"AverageTotalCost":"1,031.82"
}
}
I have parsed the response data so that there is less information to work with, especially since I only need the Accessorial Costs. The parsed response looks like
[
{
"SCAC": "test1",
"CarrierName": "TEST1",
"TransitTime": "1",
"ServiceLevel": "D",
"TotalCost": "1,031.82",
"ThirdPartyCharge": "1,031.82",
"Accessorials": {
"Accessorial": [
{
"Code": "400",
"Cost": "1,655.55",
"Description": "Freight"
},
{
"Code": "DSC",
"Cost": "-952.77",
"Description": "Discount"
},
{
"Code": "FUE",
"Cost": "329.04",
"Description": "Fuel Surcharge"
}
]
},
"QuoteNumber": ""
},
{
"SCAC": "test2",
"CarrierName": "TEST2",
"TransitTime": "1",
"ServiceLevel": "D",
"TotalCost": "1,031.82",
"ThirdPartyCharge": "1,031.82",
"Accessorials": {
"Accessorial": [
{
"Code": "400",
"Cost": "1,655.55",
"Description": "Freight"
},
{
"Code": "DSC",
"Cost": "-952.77",
"Description": "Discount"
},
{
"Code": "FUE",
"Cost": "329.04",
"Description": "Fuel Surcharge"
}
]
},
"QuoteNumber": ""
}
]
The problem I am facing is that I will never know how many Rate items will come back in the response data, nor will I know the exact amount of Accessorial Costs. I'm hoping to capture the Rate child node counts and the Accessorial child node counts per Rate. Here's what I have so far.
Root rootObject = Newtonsoft.Json.JsonConvert.DeserializeObject<Root>(responseFromServer);
//rate stores the parsed response data
JArray rate = (JArray)JObject.Parse(responseFromServer)["RatingResponse"]["Rates"]["Rate"];
var rate2 = rate.ToString();
//this for loop works as expected. it grabs the number of Rate nodes (in this example, 2)
for (int i = 0; i < rate.Count(); i++)
{
dynamic test2 = rate[i];
//this is where I'm struggling
dynamic em = (JArray)JObject.Parse(test2)["Accessorials"]["Accessorial"].Count();
for (int j = 0; j < em; j++)
{
string test3 = test2.Accessorials.Accessorial[j].Cost;
System.IO.File.AppendAllText(logPath, Environment.NewLine + test3 + Environment.NewLine);
}
}
I apologize in advance for the bad formatting and odd variable names - I'm obviously still testing the functionality, so I've been using random variables.
Where I'm struggling (as notated above) is getting to the Accessorial node to count how many items are in its array. I was thinking I could parse the first array (starting with SCAC data) and extend down to the Accessorial node, but I'm not having any luck.
Any help is GREATLY appreciated, especially since I am new to this type of code and have spent the majority of the day trying to resolve this.

Answer 1

you can try this
var rates = (JArray)JObject.Parse(json)["RatingResponse"]["Rates"]["Rate"];
var costs = rates.Select(r => new
{
CarrierName = r["CarrierName"],
Costs = ((JArray)((JObject)r["Accessorials"])["Accessorial"])
.Where(r => (string)r["Description"] != "Discount")
.Select(r => (double)r["Cost"]).Sum()
}).ToList();
result
[
{
"CarrierName": "TEST1",
"Costs": 1984.59
},
{
"CarrierName": "TEST2",
"Costs": 1984.59
}
]
