Hello all !
![:)]( ":)")
I'm just making an app that will contact a JSON webservice and return an odject to NAV 2013 R2.
But an issue is occuring when i try to use it in NAV : unable to serialize an instance of the object .NET Framework....
My assembly is in the GAC, and in the Add-in folder, signed.
I don't have this issue while trying to debug in VS2012.
I think the problem comes from my NAV C/AL Code... but can't find a solution
![:(]( ":(")
I hope someone will be able to help me

I'm using a dotnet component which one returns a collection of spécific objects created in the dev :
Objects :
public class Trade
{
public string time { get; set; }
public int type { get; set; }
public string price { get; set; }
public string amount { get; set; }
public string total { get; set; }
}
public class Trades
{
public int count { get; set; }
public List<Trade> trades { get; set; }
//public TradeList trades{get;set;}
public Trade GetTradeItem(int P_Index)
{
return trades[P_Index];
}
}
Method that return the Trade collection object after JSON serialization :
public class Stat
{
public Trades GetMarket()
{
try
{
string url = GetURL();
WebRequest request = WebRequest.Create(url);
request.Method = "GET";
WebResponse ws = request.GetResponse();
Stream s = ws.GetResponseStream();
DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(Trades));
Trades retour = (Trades)jsonSerializer.ReadObject(s);
//DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(StatItem));
//StatItem retour = (StatItem)jsonSerializer.ReadObject(s);
return retour;
}
************************ (others methods not described here) *************
}
}
NAV Code :
/////// Vars /////
Stat ==> My C# Stat Class
Item ==> My C# Trade Class
ListItem ==> My C# Trades Class
//// End var ////
Stat := Stat.Stat;
Item := Item.Trade;
ListItem := ListItem.Trades;
ListItem := Stat.GetMarket;
FOR I:=0 TO (ListItem.count-1) DO
BEGIN
Item := ListItem.GetTradeItem(I);
MESSAGE(Item.amount);
END;
But always receive the same error message :
Unable to serialize an instance of this .NET Framework object : Assembly : tradetest ......... , type Tradetest.Trades
Many thanks to my future helpers
