使用“ node：child”表示法搜索json属性的最佳方法

Question

在基于MSI的安装过程中，我们将通过参数和/或安装程序表格获取设置值。

我正在尝试动态更新应用程序appsettings文件的json属性，但不确定如何在任何深度使用“ node：child：child”键格式来搜索json。 所有选项都在表上，我们能够序列化该对象并使用反射，linq解决方案或其他任何方法。这与JSON替换之类的东西在Azure构建或发布管道中的工作原理非常相似。

除了我无法从IConfiguration中提取json字符串以将其写回到文件中之外，目前非常接近。

public static ActionResult ModifySettings(Session session)
        {
            session.Log("Begin ModifySettings");

            try
            {
                string[] customData = session.CustomActionData.Keys.ToArray();
                string[] customValues = session.CustomActionData.Values.ToArray();

                ///Product.wxs -> BinDir=[BinDir]
                var installDirectory = customValues[1];
                string file = Path.Combine(installDirectory, "appsettings.json");

                session.Log(string.Format($"Updating file: {file}.{Environment.NewLine}."));

                if (File.Exists(file))
                {
                    session.Log($"Updating Settings file: {file}.{Environment.NewLine}");

                    var configFile = new ConfigurationBuilder().AddJsonFile(file).Build();                    

                    for (int i = 3; i < customData.Count(); i++)
                    {
                        if (!ReplaceSetting(configFile, customData[i], customValues[i], session))
                            throw new ArgumentException($"Error during settings replacement of {customData[i]} with {customValues[i]}",customData[i]);
                    }

                    var settingsAsString = configFile.ToString();//DOES NOT WORK
                    session.Log($"Updated settings{Environment.NewLine}{settingsAsString}{Environment.NewLine}");
                    File.WriteAllText(file, settingsAsString);
                }
                else
                {
                    session.Log($"Failed to update file {file}.{Environment.NewLine}Exiting.");
                    return ActionResult.Failure;
                }

                return ActionResult.Success;
            }catch(Exception ex)
            {
                session.Log(ex.Message);
                return ActionResult.Failure;
            }
        }
 private static bool ReplaceSetting(IConfigurationRoot settings, string settingName, string settingValue, Session session)
        {
            try
            {
                session.Log(string.Format($"Updating Setting: {settingName}{Environment.NewLine}Value: {settingValue}{Environment.NewLine}"));
                settings[settingName] = settingValue; //<- THIS IS THE PART I NEED TO MIMIC WHEN SETTINGNAME FORMAT IS SOMETHING:SOMETHINGELSE:PROPERTY!!!
            }
            catch(Exception ex)
            {
                session.Log(ex.Message);
                return false;
            }
            return true;
        }

使用JObject的EDIT工作解决方案

 public static ActionResult ModifySettings(Session session)
        {
            session.Log("Begin ModifySettings");

            try
            {
                string[] customData = session.CustomActionData.Keys.ToArray();
                string[] customValues = session.CustomActionData.Values.ToArray();

                ///Product.wxs -> BinDir=[BinDir]
                var installDirectory = customValues[1];
                string file = Path.Combine(installDirectory, "appsettings.json");

                session.Log(string.Format($"Updating file: {file}.{Environment.NewLine}."));

                if (File.Exists(file))
                {
                    session.Log($"Updating Settings file: {file}.{Environment.NewLine}");

                    var configFile = new ConfigurationBuilder().AddJsonFile(file).Build();
                    JObject settings = JObject.Parse(File.ReadAllText(file));

                    for (int i = 3; i < customData.Count(); i++)
                    {
                        if (!ReplaceSetting(ref settings, customData[i], customValues[i], session))

                    }

                    session.Log($"Updated settings{Environment.NewLine}{settings.ToString()}{Environment.NewLine}");
                    File.WriteAllText(file, settings.ToString());
                }
                else

                return ActionResult.Failure;
            }
        }

private static bool ReplaceSetting(ref JObject settingFile, string settingName, string settingValue, Session session)
        {
