App crashes when deserializing JSON array of objects without name
I am currently working on a ListView which is showing several processes of our system. The system unfortunatedly only provide the json in the following format:
[
{
"f1": "w1",
"date": "2018.11.09"
},
{
"f1": "w2",
"date": "2018.11.09"
}
]
My app crashes if it starts the deserialization and I think the reason is, that the object has no "description". But how do I solve this?
this is my code for downloading and deserialize the json:
using (WebClient client = new WebClient())
{
client.Encoding = Encoding.UTF8;
json = client.DownloadString("http://x.x.x.x/test.json");
}
return JsonConvert.DeserializeObject<Query>(json);
Query:
public class Query
{
public List<Process> Processes { get; set; }
}
Process:
public class Process
{
[JsonProperty("f1")]
public string f1 { get; set; }
[JsonProperty("date")]
public string date { get; set; }
}

This is because JSON is trying to deserialise your values into a 'Query' object as specified:
{
"processes" :
}
When the result is a List, change the JsonConvert.DeserializeObject<Query> to JsonConvert.DeserializeObject<List<Process>>, and see if that helps :).
