cefsharp ChromiumWebBrowser，我如何将 json object 返回到 javascript，而不是字符串

Question

browser.JavascriptObjectRepository.Register("BrowerFunc", new BrowerFunc(), isAsync: false, options: bo);

 public class BrowerFunc
        {
            public string readIniData(string Section, string iniFilePath) {
                string Contentjson = JsonConvert.SerializeObject(OperateIniFile.ReadIniDataAll(Section, iniFilePath));
                return Contentjson;
            }

        }

I want the method 'readIniData' return json object,not json string.

I tried return Dictionary<string,object>,but throw some exceptions:

Uncaught Error: System.ServiceModel.CommunicationException: 读取管道时出错: 管道已结束。 (109, 0x6d)。 ---> System.IO.PipeException: 读取管道时出错: 管道已结束。 (109, 0x6d)。

My CefSharp version is 79.1.360.0,is this version too low?

You can use Json.Net for this.

JObject json = JObject.Parse(Contentjson) ;
