Deserialize Json String into my contract class.

Posted on by ShahzaibAhmed52 135
Hi, 
 
I am Desearlizing the response JSON from the API call but I get an empty contract class. below is the code that I am using to do so.
 
System.IO.StreamReader streamRead = new System.IO.StreamReader(exWeb.Response.GetResponseStream());str responseStr = streamRead.ReadToEnd();MyContract resultTopResponse = FormJsonSerializer::deserializeObject(classNum(MyContract), responseStr);
 
MyContract class contains four strings and one list. 
 
Here is the sample Response JSON.
 
{    /validationResults/: {        /infoMessages/: [],        /warningMessages/: [{                /type/: /WARNING/,                /code/: /BR-10/,                /category/: /EN_16931/,                /message/: /An Invoice shall contain the Buyer postal address (BG-8).Not applicable for simplified tax invoices and associated credit notes and debit notes (KSA-2, position 1 and 2 = 02)./,                /status/: /WARNING/            }, {                /type/: /WARNING/,                /code/: /BR-KSA-37/,                /category/: /KSA/,                /message/: /The seller address building number must contain 4 digits./,                /status/: /WARNING/            }, {                /type/: /WARNING/,                /code/: /BR-KSA-66/,                /category/: /KSA/,                /message/: /Seller postal code (BT-38) must be 5 digits./,                /status/: /WARNING/            }        ],        /errorMessages/: [{                /type/: /ERROR/,                /code/: /XSD_ZATCA_INVALID/,                /category/: /XSD validation/,                /message/: /Schema validation failed; XML does not comply with UBL 2.1 standards in line with ZATCA specifications/,                /status/: /ERROR/            }, {                /type/: /ERROR/,                /code/: /BR-16/,                /category/: /EN_16931/,                /message/: /An Invoice shall have at least one Invoice line (BG-25)/,                /status/: /ERROR/            }        ],        /status/: /ERROR/    },    /reportingStatus/: null,    /clearanceStatus/: /NOT_CLEARED/,    /qrSellertStatus/: null,    /qrBuyertStatus/: null}
 
Here is the code in MyContract Class:
[DataContractAttribute]class MyContract{    str reportingStatus, clearanceStatus, qrSellertStatus, qrBuyertStatus;    list  validationResults;    [DataMemberAttribute(/reportingStatus/)]    public str parmReportingStatus(str _reportingStatus = reportingStatus)    {        reportingStatus = _reportingStatus;        return reportingStatus;    }    [DataMemberAttribute(/clearanceStatus/)]    public str parmClearanceStatus(str _clearanceStatus = clearanceStatus)    {        clearanceStatus = _clearanceStatus;        return clearanceStatus;    }    [DataMemberAttribute(/qrSellertStatus/)]    public str parmQrSellertStatus(str _qrSellertStatus = qrSellertStatus)    {        qrSellertStatus = _qrSellertStatus;        return qrSellertStatus;    }    [DataMemberAttribute(/qrBuyertStatus/)]    public str parmQrBuyertStatus(str _qrBuyertStatus = qrBuyertStatus)    {        qrBuyertStatus = _qrBuyertStatus;        return qrBuyertStatus;    }    [DataMemberAttribute(/validationResults/), DataCollection(Types::Class, classStr(MyContract2))]    public list parmValidationResults(list _validationResults = validationResults)    {        validationResults = _validationResults;        return validationResults;    }}

    Hi Shahzib,

    What is exWeb.Response? you didn't show us full code
    and what is rac resultTopResponse? why you didn't replace it with your contract?

    it should be sth like this: 
    str response;
System.Net.HttpWebResponse hhtpResponse= request.GetResponse(); //assume request is defined (System.Net.WebRequest), maybe this is your exWeb.Response
 
using (System.IO.StreamReader streamReader  = new System.IO.StreamReader(hhtpResponse.GetResponseStream()))
{
   response = streamReader.ReadToEnd();
}

MyContract myContract= new MyContract();
myContract = FormJsonSerializer::deserializeObject(classNum(MyContract),  response) as MyContract;

    Thanks,
    Layan Jweihan

    Deserialize Json String into my contract class.
    In my case, It worked as I made the following changes in mycontract class.
     
    I changed 'validationResults' to Mycontract2 from a list. As my in my JSON 'validationResults' was not an array.
     
    [DataContractAttribute]
class MyContract
{
    str reportingStatus, clearanceStatus, qrSellertStatus, qrBuyertStatus;

    MyContract2 validationResults;

    [DataMemberAttribute("reportingStatus")]
    public str parmReportingStatus(str _reportingStatus = reportingStatus)
    {
        reportingStatus = _reportingStatus;
        return reportingStatus;
    }

    [DataMemberAttribute("clearanceStatus")]
    public str parmClearanceStatus(str _clearanceStatus = clearanceStatus)
    {
        clearanceStatus = _clearanceStatus;
        return clearanceStatus;
    }

    [DataMemberAttribute("qrSellertStatus")]
    public str parmQrSellertStatus(str _qrSellertStatus = qrSellertStatus)
    {
        qrSellertStatus = _qrSellertStatus;
        return qrSellertStatus;
    }

    [DataMemberAttribute("qrBuyertStatus")]
    public str parmQrBuyertStatus(str _qrBuyertStatus = qrBuyertStatus)
    {
        qrBuyertStatus = _qrBuyertStatus;
        return qrBuyertStatus;
    }

    [DataMemberAttribute("validationResults"), DataCollectionAttribute(Types::Class, classStr(MyContract2))]
    public MyContract2 parmValidationResults(MyContract2_validationResults = validationResults)
    {
        validationResults = _validationResults;
        return validationResults;
    }

}
