How to read dynamic returned JSON string in c#?

Question

I have a an Apple API which returns the Apple Device information using the SerialNumber/IMEI number and returns the JSON string.

And have successfully have created a Classes using JSON to C# Class Converter and it works fine. But, the problem is, when i make a call for Out of Warranty[the device which has passed warranty it returns different JSON] device it returns JSON with different Key,Values hence the casting of RootObject fails.

JSON 1: [For in Warranty Device]

}

Source Code:

public class AppleAPI
{
    public IosInfo ios_info { get; set; }
    public ProductInfo product_info { get; set; }

    public bool error { get; set; }
    public string error_message { get; set; }
    public AppleAPI()
    {
        //
        // TODO: Add constructor logic here
        //
    }
    public string VerifyAppleESN(string esn)
    {
        string responseText = string.Empty;
    //Apple API code here
        return responseText;
    }
}
public class IosInfo
{
    public string serialNumber { get; set; }
    public string imeiNumber { get; set; }
    public string meid { get; set; }
    public string iccID { get; set; }
    public string firstUnbrickDate { get; set; }

    public string bluetoothMacAddress { get; set; }
    public string partDescription { get; set; }
}

public class ConsumerLawInfo
{
    public string serviceType { get; set; }
    public string popMandatory { get; set; }
    public string allowedPartType { get; set; }
}

public class ProductInfo
{
    public string serialNumber { get; set; }
    public string warrantyStatus { get; set; }
    public string coverageEndDate { get; set; }
    public string coverageStartDate { get; set; }
    public string daysRemaining { get; set; }

    public string manualURL { get; set; }
    public string productDescription { get; set; }
    public string configDescription { get; set; }
    public string slaGroupDescription { get; set; }
    public string contractCoverageEndDate { get; set; }
    public string contractCoverageStartDate { get; set; }
    public string contractType { get; set; }
    public string laborCovered { get; set; }
    public string limitedWarranty { get; set; }
    public string partCovered { get; set; }
    public string notes { get; set; }
    public string acPlusFlag { get; set; }
    public ConsumerLawInfo consumerLawInfo { get; set; }
}

Deserialisation of JSON:

string responseText = string.Empty;
AppleAPI appobj = new AppleAPI();
responseText = appobj.VerifyAppleESN(newEsn);
//Below line works only wen Device is in Warranty & if Out of Warranty it gives error.
var resobj = JsonConvert.DeserializeObject<AppleAPI>(responseText);

So, i want to know whether we can read the Dynamic returned JSON string and display in html table without knowing its key and number of items.

NOTE: I am using .NET Framework 3.5 so can't use dynamic key word as many samples are available using version 4.0

Update:

var resDict = JsonConvert.DeserializeObject<Dictionary<string, object>>(responseText);
  string sdict = string.Empty;
  string innertval = string.Empty;
  foreach (string key in resDict.Keys)
  {
      sdict += "<br/> " +key+" "+ resDict[key].ToString();
  }

After trying the suggested code from @tt_emrah and modifying at certain extent i got the following STRING :

ios_info Provided serial number does not belong to an iOS Device.Please Enter an ios serial number.
product_info { "serialNumber": "C02HW2LGDKQ", "warrantyStatus": "Out Of Warranty (No Coverage)", "daysRemaining": "0", "estimatedPurchaseDate": "07/20/12", "purchaseCountry": "United States", "registrationDate": "", "imageURL": "http://service.info.apple.com/parts/service_parts/na.gif", "explodedViewURL": "http://service.info.apple.com/manuals-ssol.html", "manualURL": "http://service.info.apple.com/manuals-ssol.html", "productDescription": "MacBook Pro (Retina, Mid 2012)", "configDescription": "MBP 15.4/2.3/8GB/256GB FLASH", "slaGroupDescription": "", "acPlusFlag": "", "consumerLawInfo": { "serviceType": "", "popMandatory": "", "allowedPartType": "" } }

But how to get the values as Key:Value format.

NOTE: The returned JSON string may change. so Independent of returned JSON string just want to display it as Key:Values

Example:

     serialNumber:C02HW2LGDKQ
     warrantyStatus:Out of Warranty(No Coverage)
     .
     (n) key:values

Help Appreciated!

You might have to inspect the string before you deserialize to determine if it's in or out of warranty and then deserialize to a different class for out-of-warranty. — Matt Burland

hi @MattBurland! YES! I have already created different class for Out of warranty and it works. But, what if wen i get some other JSON string other than these two? As its "Undetermined" and "UNKNOWN". So, i need something that will just read any JSON string and display in HTML Table. Any idea? — SHEKHAR SHETE

Without dynamic types, that's pretty tough. You might be able to convert your string to a dictionary perhaps? This question might help: stackoverflow.com/questions/14886800/… — Matt Burland

why not deserialize the string into a dictionary, and then iterate through it's keys for the display part?

    private string GetKeyValuePairs(string jsonString)
    {
        var resDict = JsonConvert.DeserializeObject<Dictionary<string, object>>(jsonString);
        string sdict = string.Empty;
        foreach (string key in resDict.Keys)
        {
            sdict += "<br/> " + key + " : " + (resDict[key].GetType() == typeof(JObject) ? GetKeyValuePairs(resDict[key].ToString()) : resDict[key].ToString());
        }
        return sdict;
    }

hi @tt_emrah, please check the "Update" in main post! Help Appreciatd!

tt_emrah Over a year ago

you can do it in a recursive method, and check every value if it is also an instance of JObject. i modified my code above.
