JSON DeserializeObject to Model without Key Name

I currently have JSON coming in as follows:
{"36879":[{"min_qty":1,"discount_type":"%","csp_price":10}],"57950":[{"min_qty":1,"discount_type":"flat","csp_price":650}]}
This contains a list of the following records
ProductId
MinQty
DiscountType
Price
I need to deserialize this into the following model:
public class CustomerSpecificPricing
{
string productId { get; set; }
public virtual List<CustomerSpecificPricingDetail> CustomerSpecificPricingDetails { get; set; }
}
public class CustomerSpecificPricingDetail
{
public string min_qty { get; set; }
public string discount_type { get; set; }
public string csp_price { get; set; }
}
The problem is that the "productId" of each record is missing the key name.
If I run my JSON through J2C, I get the following:
public class 36879 {
public int min_qty { get; set; }
public string discount_type { get; set; }
public int csp_price { get; set; }
}
public class 57950 {
public int min_qty { get; set; }
public string discount_type { get; set; }
public int csp_price { get; set; }
}
public class Root {
public List<_36879> _36879 { get; set; }
public List<_57950> _57950 { get; set; }
}
Which is obviously incorrect.
How would I deserialize my object correctly?

You would need to deserialize it into a dictionary first and then map it into the format you require after. Something like this should work:
var dict = JsonConvert.DeserializeObject<Dictionary<string, IEnumerable<CustomerSpecificPricingDetail>>>();
var result = dict.Select(kvp => new CustomerSpecificPricing { ProductId = Int32.Parse(kvp.Key), CustomerSpecificPricingDetails = kvp.Value });
Id also recommend you follow the conventional standards of naming. In this case properties in classes should be PascalCase,
e.g. your classes now become:
public class CustomerSpecificPricing
{
[JsonProperty("productId ")]
public string ProductId { get; set; }
public virtual List<CustomerSpecificPricingDetail> CustomerSpecificPricingDetails { get; set; }
}
and
public class CustomerSpecificPricingDetail
{
[JsonProperty("min_qty")]
public string MinQty { get; set; }
[JsonProperty("discount_type ")]
public string DiscountType { get; set; }
[JsonProperty("csp_price ")]
public string CspPrice { get; set; }
}

How to use json.net to Deserialize a nested class?

I have the following class
public class CallbackResultsJson
{
public class CallbackResults
{
public string Status { get; set; }
public string Message { get; set; }
public string Data { get; set; }
public string Log { get; set; }
public string StatusText { get; set; }
public string TransactionToken { get; set; }
}
}
I am trying to use Json.Net to Deserialize requestbody but I am always getting a null for status,data. any ideas why ?
var requestbody =#"
{
"CallbackResults":
{
"TransactionToken":"b65524-qwe",
"Status":0,
"Message":"Publish Application to QaLevel Operation Completed",
"Data":[],
"Log":["sucess"
},
"RequestNumber":"REQ1234"
}"
var TransactionResult = JsonConvert.DeserializeObject<CallbackResultsJson.CallbackResults>(requestBody);

Just a little bit of change should be done.
Your class:
public class CallbackResultsJson
{
public CallbackResultsClass CallbackResults { get; set; }
public string RequestNumber { get; set; }
public class CallbackResultsClass
{
public int Status { get; set; }
public string Message { get; set; }
public string[] Data { get; set; }
public string Log { get; set; }
public string TransactionToken { get; set; }
}
}
Your data:
var requestbody = #"
{
""CallbackResults"":
{
""TransactionToken"":""b65524-qwe"",
""Status"":0,
""Message"":""Publish Application to QaLevel Operation Completed"",
""Data"":[""Data1"", ""Data2""],
""Log"":""sucess""
},
""RequestNumber"":""REQ1234""
}";
var result = JsonConvert.DeserializeObject<CallbackResultsJson>(requestbody);

Your class needs to have a property of the sub-type,
public class CallbackResultsJson
{
public CallBackResults CallbackResults { get; set; }
public string RequestNumber { get; set; )
public class CallbackResults
{
public string Status { get; set; }
public string Message { get; set; }
public string Data { get; set; }
public string Log { get; set; }
public string StatusText { get; set; }
public string TransactionToken { get; set; }
}
}
var result = JsonConvert.DeserializeObject<CallbackResultsJson>(requestBody);

I have used json2csharp.com to convert requestbody to c# classes and it generated these classes.it worked
public class CallbackResults
{
public string TransactionToken { get; set; }
public int Status { get; set; }
public string Message { get; set; }
public List<string> Data { get; set; }
public List<string> Log { get; set; }
}
public class CallbackResultsRootObj
{
public CallbackResults VdiCallbackResults { get; set; }
public string RequestNumber { get; set; }
}
var vdiTransactionResult = JsonConvert.DeserializeObject<CallbackResultsRootObj>(requestBody);

c# load Json into inherited class

I have a C# classes and I need to parse JSON into it.
The class has a List<> from another class.
The class structure is like this.
public class OrderFund {
public int OrderID { get; set; }
public int BrokerID { get; set; }
public string SettlementMethod { get; set; }
public List<SettlementSap> SettlementsSap { get; set; }
}
public class SettlementSap {
public string SapMonetaryAccountNo { get; set; }
public string SapMonetaryAccountType { get; set; }
public string SapMonetaryAccountOffice { get; set; }
}
My JSON is like this.
{
"settlementMethod": "SAP",
"BrokerID": 1,
"OrderID": 1,
"Settlements": [
{
"SapMonetaryAccountNo": "400245892464",
"SapMonetaryAccountType": "CA",
"SapMonetaryAccountOffice": "AR"
}
]
}
I load my JSON file like this...
static OrderFund LoadJson(string file) {
string dire = Directory.GetCurrentDirectory();
using (StreamReader r = new StreamReader(dire + "\\" + file)) {
string json = r.ReadToEnd();
OrderFund items = JsonConvert.DeserializeObject<OrderFund>(json);
return items;
}
}
The data load fine into OrderFun Class but OrderFund.SettlementsSap is null.
How can I load Settlements into SettlementsSap?

That's because you have named the field SettlementsSap but your Json field is called Settlements...
You could rename the field in your class;
public class OrderFund
{
public int OrderID { get; set; }
public int BrokerID { get; set; }
public string SettlementMethod { get; set; }
public List<SettlementSap> Settlements { get; set; }
}
or add a [JsonProperty("Settlements")]
attribute to the field like so;
public class OrderFund
{
public int OrderID { get; set; }
public int BrokerID { get; set; }
public string SettlementMethod { get; set; }
[JsonProperty("Settlements")]
public List<SettlementSap> SettlementsSap { get; set; }
}

You just use a function of Visual Studio which convert your json into a model class
Goto: Edit -> Paste special -> Paste JSON as Class
The model class created by this feature will solve your problem
So, visiblely, you must rename SettlementsSap by Settlements
public class OrderFund
{
public string settlementMethod { get; set; }
public int BrokerID { get; set; }
public int OrderID { get; set; }
public Settlement[] Settlements { get; set; }
}
public class Settlement
{
public string SapMonetaryAccountNo { get; set; }
public string SapMonetaryAccountType { get; set; }
public string SapMonetaryAccountOffice { get; set; }
}

The problem is with the naming. In the JSON, the name is Settlements. But in the class definition of OrderFund it is named as SettlementsSap

How to specify a class that may contain another class

I want to create a class that have a class but this second class may be different each time the first class is called. For example:
public class ServerResponseObject
{
public string statusCode { get; set; }
public string errorCode { get; set; }
public string errorDescription { get; set; }
public Object obj { get; set; }
public ServerResponseObject(Object obje)
{
obj = obje;
}
}
public class TVChannelObject
{
public string number { get; set; }
public string title { get; set; }
public string FavoriteChannel { get; set; }
public string description { get; set; }
public string packageid { get; set; }
public string format { get; set; }
}
public class ChannelCategoryObject
{
public string id { get; set; }
public string name { get; set; }
}
How can I do it to call the ServerResponseObject with different objects each time, once with TVChannelObject and once with ChannelCategoryObject?

What you're looking for is a generic type parameter:
public class ServerResponseObject<T>
{
public ServerResponseObject(T obj)
{
Obj = obj;
}
public T Obj { get; set; }
}

Generate C# object from Json string and parse Json string to generated object

I am trying to generate C# class using the JSON string from here http://json2csharp.com/ this works fine. But I can't parse the JSON to the object generated by the website.
Here is the JSON string

Here is the code I use to convert to the object.
JavaScriptSerializer js = new JavaScriptSerializer();
var xx = (PersonsearchVM)js.Deserialize(jsonstr, typeof(PersonsearchVM));
Is there any other wat to generate the object and parse?

I think you have some invalid characters in your JSON string. Run it through a validator and add the necessary escape characters.
http://jsonlint.com/

You aren't casting it to the right object. Cast it to the type RootObject.
Eg
JavaScriptSerializer js = new JavaScriptSerializer();
var xx = (RootObject)js.Deserialize(jsonstr, typeof(RootObject));
The code that json 2 csharp creates is this:

The following function will convert JSON into a C# class where T is the class type.
public static T Deserialise<T>(string json)
{
T obj = Activator.CreateInstance<T>();
using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json)))
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType());
obj = (T)serializer.ReadObject(ms); //
return obj;
}
}
You need a reference to the System.Runtime.Serialization.json namespace.
The function is called in the following manner;
calendarList = Deserialise<GoogleCalendarList>(calendarListString);
calendarlist being the C# class and calendarListString the string containing the JSON.
