I want to use RestAPI from D365. We tried following approached
• Use newtonsoft Dll.
• Use “FormJsonSerializer“ class
And we are facing the following issue
• Unable to serialize and deserialize objects using newtonsoft dll. Always return blank object.
• We are able to serialize and deserialize object using FormJsonSerializer but if rest call contains multiple List objects then its throwing error.
[DataContract]
public final class ExUnattachedReceipt
{
private Description name;
private int amount;
private str createdDate;[DataMember('name')]
public str parmName(str _name = name)
{
name = _name;
return name;
}[DataMember('amount')]
public int parmAmount(int _amount = amount)
{
amount = _amount;
return amount;
}[DataMember('createdDate')]
public str parmCreatedDate(str _createdDate = createdDate)
{
createdDate = _createdDate;
return createdDate;
}}
We can directly call FormJsonSerializer::serializeClass(ExUnattachedReceipt);
-------------------------------------------------------------------------------------------------------------------------------------------------------------
Now lets take their another scenerio where above class is added as Collection and we want to serialize outer class
[DataContract]
public final class ExUnattachedReceiptList
{
private List exReceipts = new List(Types::Class);[DataMember('exReceipts'),
DataCollection(Types::Class, classStr(ExUnattachedReceipt))]
public List parmExReceipts(List _exReceipts = exReceipts)
{
exReceipts = _exReceipts;
return exReceipts;
}
}
In case anyone finds this. The output is empty because Newtonsoft is deliberately ignoring your data members.
The x compiler takes each DataMember attribute and makes a dotnet property out of it. That property is marked as "compiler generated", and Json.net will ignore compiler generated properties by default.
So, to serialise/deserialise an x object you have to tell Json.net to include compiler generated properties.

public static str Serialise(Object _obj)
{
Newtonsoft.Json.Serialization.DefaultContractResolver resolver = new Newtonsoft.Json.Serialization.DefaultContractResolver();
resolver.SerializeCompilerGeneratedMembers = true;
Newtonsoft.Json.JsonSerializerSettings settings = new Newtonsoft.Json.JsonSerializerSettings();
settings.ContractResolver = resolver;
return Newtonsoft.Json.JsonConvert::SerializeObject(_obj, settings);
}
public class Product
{
public string Id { get; set; }
public str Name { get; set; }
}
YourCSharpLib.Product product = new YourCSharpLib.Product(); product.Id = "1"; product.Name = "Test"; str json = Newtonsoft.Json.JsonConvert::SerializeObject(product, Newtonsoft.Json.Formatting::Indented);
Show us please inbound JSON message.
If your message contain a list of your datacontracts (DC), then you have to wrap AX DC to another DC, like:
[DataContractAttribute]
class DataContractClass
{
DataAreaId dataAreaId;
List subContractList;
[DataMemberAttribute('DataAreaId')]
public Description parmDataAreaId(DataAreaId _dataAreaId = dataAreaId)
{
dataAreaId = _dataAreaId;
return dataAreaId;
}
[DataMemberAttribute('SubContractList'),
AifCollectionTypeAttribute('_subContractList', Types::Class, classStr(SubContractDataContract))]
public List parmSubContractList(List _subContractList = subContractList)
{
subContractList = _subContractList;
return subContractList;
}
}
====
To serialize/deserialize DC use:
DataContractClass dataContract = new DataContractClass();
dataContract.parmDataAreaId('ABCD');
List subContractDCList = new List(Types::Class);
SubContractDataContract subContractDC = new SubContractDataContract();
subContractDC.parmCustomerAccount('ABCD-000001');
subContractDCList.addEnd(subContractDC);
dataContract.parmProjContractList(subContractDCList);
//serialize DC -> JSON
str jsonSerializedContract = FormJsonSerializer::serializeClass(dataContract);
//deserialize JSON -> DC
Object deserializedDc = FormJsonSerializer::deserializeObject(classIdGet(dataContract), jsonSerializedContract);
List deserializedSubDcList = deserializedDc.parmSubContractList();
if (deserializedSubDcList)
{
ListEnumerator le_DeserializedSubDc = deserializedSubDcList.getEnumerator();
while (le_DeserializedSubDc.moveNext())
{
SubContractDataContract deserializedSubDc = le_DeserializedSubDc.current();
//Actions with subDC
}
}
Hi
There is another easy way to handle your case.. if you can consume web service from C# client and only get response on D365.
We have the same requirement previously in one of our project. To achieve this We created everything in C# project even the attribute classes and consume the services as well with in C#.
Then add the reference of the C# project DLLs in D365FO and call the method to consume the service. even all type of serialization we were performing on C# end.
If you are still facing any issue do let me know we can discuss this in detail.
We have created the Class as
[DataContractAttribute]
public class Product
{
private str id1;
Private str name1;
[DataMemberAttribute]
public str id(str _id=id1)
{
id1 = _id;
return id1;
}
[DataMemberAttribute]
public str name(str _name=name1)
{
name1 = _name;
return name1;
}
}
Create on runnable call and added following code
Str json;
product = new Product();
product.id("1");
product.name("Test");
json = Newtonsoft.Json.JsonConvert::SerializeObject(product,Newtonsoft.Json.Formatting::Indented);
info (json);
Newton soft always return blank Json string.
