addressInfo or ChainStats is null So it appears that there's something wrong with the JSON deserialization Can you show the structure of AddressInfo? And what does the JSON string look like?

wdym json string look like?

public class AddressInfo
    {
        public string Address { get; set; }
        public ChainStats ChainStats { get; set; }
    }

public class AddressInfo
    {
        public string Address { get; set; }
        public ChainStats ChainStats { get; set; }
    }

You are deserializing a string. It's value is in the format of json . Copy the value of the string you are deserializing And paste it here

x0rld•2y ago

the json should look like that in json variable

{
"address": ""
"ChainStats": {..}
}

{
"address": ""
"ChainStats": {..}
}

Denis•2y ago

The value of the json variable at line 87 to be specific

tf why it just work out of thin air

Connection issue?

slotsclassic•2y ago

all i added since then was a "with balance capture" put into my if(balance > 0) withBal++.ToString();

x0rld•2y ago

don't do a ++ and another operation ( ToString) at same time it's a really make it super harder to read

Thinker•2y ago

Could be that, since you're calling an external API, that the API just happened to return null or unauthorized or something at that point

slotsclassic•2y ago

thats always how i capture int values, how would you be doing it? so an error from the API and not my code

Thinker•2y ago

perhaps

x0rld•2y ago

you want to have the string before or after adding +1 to your variable ?

Thinker•2y ago

You should probably do a null check after the AddressInfo addressInfo = ... line.

x0rld•2y ago

I just say do that instead of one line it it's much easier to read

withBal++;
withBal.ToString();

withBal++;
withBal.ToString();

Denis•2y ago

Less lines != Good code

btw you could use directly this method to deserialize instead of getting string, then read it, then deserialize it https://learn.microsoft.com/en-us/dotnet/api/system.net.http.json.httpclientjsonextensions.getfromjsonasync?view=net-7.0

slotsclassic•2y ago

well, shits fixed now. Now i just have to add proxy support so i wont get timeout

Buddy•2y ago

What are you making?

slotsclassic•2y ago

tbh project is useless, but a good practise thing its just gens a mnemonic and checks for the balance through an API

Buddy•2y ago

eh, ok lol

slotsclassic•2y ago

but the chance of actually finding a lost crypto wallet with it is 0.00000000000000000000000000000000000000684%

Buddy•2y ago

So what does it actually achieve?

slotsclassic•2y ago

My practise skills with web requests only tbh nothing else practise using loops
