✅ Newtonsoft.Json JsonSerializationException

As the title says, I keep getting a JsonSerializationException. I have no idea how to view the Exception details so if anyone could tell me that'd be nice. I've followed a few tutorials on this topic, but absolutely none have worked. Two exceptions occur in System.Private.CoreLib.dll and one in Newstonesoft.Json.dll

private async Task LoadData()
 {
 var clientJson = System.IO.File.ReadAllText(clientDataPath);
 Classes.Spark.DebugLog(clientJson);
 var clientData = JsonConvert.DeserializeObject<ClientData(clientJson);
}

public class ClientData
{
    public string Client_ID { get; set; }
    public string Client_Secret {  get; set; }

    public string Refresh_Token { get; set; }
    public string Access_Token { get; set; }
}

private async Task LoadData()
 {
 var clientJson = System.IO.File.ReadAllText(clientDataPath);
 Classes.Spark.DebugLog(clientJson);
 var clientData = JsonConvert.DeserializeObject<ClientData(clientJson);
}

public class ClientData
{
    public string Client_ID { get; set; }
    public string Client_Secret {  get; set; }

    public string Refresh_Token { get; set; }
    public string Access_Token { get; set; }
}

Btw here is the the string that clientJson prints [{"Client_ID":"SECRET","Client_Secret":"SECRET","Refresh_Token":"%null%","Access_Token":"%null%"}]

well that is not ClientData and you're missing a > in your code [] represents a list/array so List<ClientData>

mandatory use System.Text.Json instead of Newtonsoft.Json

FumetsuOP•2d ago

Oh the second > is just gone in the message for some reason Is there a good reason not to use Newtonsoft? I heard it was faster than the default JsonSerializer

ero•2d ago

no, it's the other way around, by a long shot

FumetsuOP•2d ago

Ohhh okay, that's great actually because there's more tutorials on the default lol. Thanks for that information

because nsj was created when there was nothing standardized to do the job or in the BCL now there is, which is STJ which was created by the same people who made nsj. so yes prefer STJ over NSJ unless you have a very specific use case and fked up json to deal with.

FumetsuOP•2d ago

Ahhh okay thank you very much. I'll try using STJ and see how it fares

leowest•2d ago

anyway the json u posted is not just ClientData so u need to either use array or list

FumetsuOP•2d ago

Ahhh sorry I'm not well versed in this stuff, how would I go about that?

ero•2d ago

.Deserialize<ClientData[]>

FumetsuOP•2d ago

Ahh okay thank you. Using that it made progress, I just have to adjust some other stuff now
