Parsing List of JSON Elements as List With JSON.Net

You can use simple Jsonconvert.Deserialize<yourType>(jsonString) to get the typed object from the JSON. But this can throw an error if the items in JSON have a field with an incorrect value. Let's an int field have some alphabetic character. The exception will be thrown for parsing and you'll have very little details on the error.

Now if you need to parse it as a list and let's say you want to find elements with fields that are not of the correct type as it should be then we can filter them out and log them somewhere. And so you will get a complete list of correct items and corrupted data.

We'll use a JArray class from the namespace Newtonsoft.Json.Linq to parse the data as a list of arrays of objects and then we'll convert one by one each item to a typed object and add it to the list. Here's the sample generic deserializer that can parse JSON and get the valid and invalid elements.

Usage

So here you can see that you'll have valid items in the list and invalid errors. For an example of the preceding JSON data, the last element has an invalid value to an int field major as '1AAA'.
