如何使用Json.NET读取带有注释的JSON内容? [英] How can I read JSON content with a comment with Json.NET?

问题描述

为了将外部扩展安装到Google Chrome浏览器中，我尝试更新Chrome外部扩展JSON文件.使用Json.NET似乎很容易:

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);

但是我得到一个Newtonsoft.Json.JsonReaderException话:

"Error parsing comment. Expected: *, got /. Path '', line 1, position 1."

在调用JObject.Parse时，因为此文件包含:

when calling JObject.Parse because this file contains:

// This JSON file will contain a list of extensions that will be included
// in the installer.

{
}

注释不是JSON的一部分(如

And comments are not part of JSON (as seen in How do I add comments to Json.NET output?).

我知道我可以使用正则表达式(

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.

有没有一种方法可以读取带注释的JSON内容而不删除它们并能够重写它们?

Is there a way to read JSON content with comments without removing them and be able to rewrite them?

推荐答案

Json.NET仅支持阅读多行JavaScript注释，即/*注释*/

Json.NET only supports reading multi-line JavaScript comments, i.e. /* commment */

更新:Json.NET 6.0支持单行注释

Update: Json.NET 6.0 supports single line comments
