One of the features in NewtonSoft's Json.Net parser is the support of unquoted property name, for example {test:"abc"}. Is it possible to turn off this feature so the json parser will throw an error when it parses a json string with unquoted property name?
回答1:
What you can do is to deserialize and then serialize again and compare with original input. That will detect missing quotes. Even if this is not performance efficient, it is very simple and serves well when the relevant code performance does not matter much.
