How can I read JSON content with a comment with Json.NET?
c#, json.net
Solution
Json.NET only supports reading multi-line JavaScript comments, i.e. /* commment */
Update: Json.NET 6.0 supports single line comments
Problem
In order to install an external extension into Google Chrome browser, I try to update a Chrome external extension JSON file. Using `Json.NET` it seems to be easy: ``` string fileName = "..."; // Path to a Chrome external extension JSON file string externalExtensionsJson = File.ReadAllText(fileName); JObject externalExtensions = JObject.Parse(externalExtensionsJson); ``` but I get a `Newtonsoft.Json.JsonReaderException` saying: ``` "Error parsing comment. Expected: *, got /. Path '', line 1, position 1." ``` when calling `JObject.Parse` because this file contains: ``` // This JSON file will contain a list of extensions that will be included // in the installer. { } ``` And comments are not part of JSON (as seen in How do I add comments to Json.NET output?). I know I can remove comments with a regular expression (Regular expression to remove JavaScript double slash (//) style comments), but I need to rewrite JSON into the file after modification and keeping comment can be a good thing. Is there a way to read JSON content with comments without removing them and be able to rewrite them?
