1 lut 2020 · This solution uses a custom JsonConverter in System.Text.Json. If some_object is an array then it will return an empty object (or null if you prefer), and no exception will be thrown. Otherwise it will correctly deserialize the json.
8 paź 2014 · The exception depends on what actually failed, for example, I took some valid JSON and removed the closing '}' and it threw a JsonSerializationException. Yet if I change it to be not JSON like at all (i.e. just a word or even HTML), it threw JsonReaderException .
The result of deserializing the JSON is three successfully deserialized dates and three error messages: one for the badly formatted string ("I am not a date and will error!"), one for the nested JSON array, and one for the null value since the list doesn't allow nullable DateTimes.

A simpler workaround, which may not be performant, involves using JsonElement to handle the brute force checking of each item: JsonElement jsonArray = JsonSerializer.Deserialize<JsonElement>(jsonString); List<Person> people = new List<Person>(); foreach (var element in jsonArray.EnumerateArray()) { try ...

For example, we can use the JsonSerializerDefaults class to choose the Web option. // camelCase var web = JsonSerializer.Deserialize<Person []> (json, new JsonSerializerOptions (JsonSerializerDefaults.Web)); Console.WriteLine ($"web: {web? [0]}");
