将JObject添加到JObject [英] Add JObject to JObject

问题描述

我有一个像这样的json结构:

I have a json structure like this:

var json = 
{
  "report": {},
  "expense": {},
  "invoices": {},
  "projects": {},
  "clients": {},
  "settings": {
    "users": {},
    "companies": {},
    "templates": {},
    "translations": {},
    "license": {},
    "backups": {},
  }
}

我想向json添加一个新的空对象，例如"report":{}.

I would like to add a new empty Object like "report":{} to the json

我的C#代码是这样的:

My C# code is like this:

JObject json = JObject.Parse(File.ReadAllText("path"));
json.Add(new JObject(fm.Name));

但是它给了我一个例外:无法将Newtonsoft.Json.Linq.JValue添加到Newtonsoft.Json.Linq.JObject

But it it gives me a exception: Can not add Newtonsoft.Json.Linq.JValue to Newtonsoft.Json.Linq.JObject

所以，如何将新的空JObject添加到json

So, how can I add a new and empty JObject to the json

预先感谢

推荐答案

出现此错误的原因是，您试图使用字符串构造JObject(该字符串将转换为JValue).为此，JObject不能直接包含JValue，也不能包含另一个JObject.它只能包含JProperties(依次包含其他JObjects，JArrays或JValues).

You are getting this error because you are trying to construct a JObject with a string (which gets converted into a JValue). A JObject cannot directly contain a JValue, nor another JObject, for that matter; it can only contain JProperties (which can, in turn, contain other JObjects, JArrays or JValues).

要使其正常运行，请将第二行更改为:

To make it work, change your second line to this:

json.Add(new JProperty(fm.Name, new JObject()));
