使用 Newtonsoft 在值中使用引号反序列化 JSON

Question

I am retrieving JSON from an API and have the following problem: Some Json-values look like this and cannot be serialized the standard way

"key": "This is just a "dummy" value to show the problem",

The problem are the quotes around dummy. Newtonsoft obviously thinks the value ends with the quote before dummy, but it actually ends after problem. Is there a way to ignore those quotes or somehow remove them automatically?

I've tried to remove them with a StringBuilder and String-Replace, but that didn't work because such a pattern occures mutliple times in the JSON-File and sometimes the nested quotes quote a single word, sometimes a whole sentence.

The whole JSON from the API has around 50.000 lines, so it's impossible to correct the error by hand.

Can this be solved somehow in C#?

Answer 1

Update: You have to write a custom parser to parse since its clearly not JSON then. What you have to do is fix the serialized object before you deseriliaze it. You have to iterate through the entire string and remove the unrequired quotes.

An example would be when the value property of a JSON ends and next one begins there is a comma character in the middle.

Its basically a huge nested if condition, to fix this.

As you can see, it does not parse as an valid JSON. You have to represent quotes as below. If its not someting in your control, you have to come up with a custom parser.
