How To Create And Query Json Documents In Oracle 12c Learn how to read an external local json file in javascript using different methods and techniques. The pretty picture also lists all of the legitimate escape sequences within a json string: \" \\ \ \b \f \n \r \t \u followed by four hex digits note that, contrary to the nonsense in some other answers here, \' is never a valid escape sequence in a json string. it doesn't need to be, because json strings are always double quoted. Bson is the binary encoding of json like documents that mongodb uses when storing documents in collections. it adds support for data types like date and binary that aren't supported in json. in practice, you don't have to know much about bson when working with mongodb, you just need to use the native types of your language and the supplied types (e.g. objectid) of its driver when constructing. The main issue seems to be that the original solution treats the json purely as a dictionary, when in fact it is a dictionary within a list, within a dictionary, within a dictionary.

It's unfortunate that the answers all seem to answer the question "how do i serialize a class?" rather than the action question "how do i make a class serializable?" these answers assume that you're doing the serialization yourself, rather than passing the object along to some other module that serializes it. There's json in system.web.helpers, there's jsonquerystringconverter in system.servicemodel.web, there's javascriptserializer in system.web.script.serialization, datacontractjsonserializer in system.runtime.serialization.json, heck ms has even decided to include third party json in its asp web api. if you thought that wasn't enough, ms is coming up with system.json but currently is. Json dump will write the json as string in the file. how can i get a json file that is not in the form of string, but just dictionary like? is it possible?.
