添加到JArray的JSON.NET

我有一个json数组要添加到其中，然后将内容写入一个文件。将内容添加到数组中没有问题，但使用JsonSerializer.Serialize方法写入文件时会出现异常：

例外情况： 无法将Newtonsoft.Json.Linq.JObject添加到Newtonsoft.Json.Linq.JObject

这发生在我下面代码的最后一行。jSerializer.Serialize（o.CreateWriter（），o）

JSON

操作JSON对象的代码

JContainer o = (JObject)JToken.ReadFrom(new JsonTextReader(reader));
JArray x = (JArray)o["ArrayToManipulate"];
ContentObject newObject = new ContentObject(){Name="Value"};
JToken tokenToAdd = JToken.Parse(JsonConvert.SerializeObject(newObject, Formatting.Indented));
x.Add(tokenToAdd);
JsonSerializer jSerializer = new JsonSerializer();
jSerializer.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
jSerializer.Serialize(o.CreateWriter(), o);

我这样做是错误的吗？

通过调用

JContainer.CreateWriter

得到的writer不会像您希望的那样写入文件-它是一个写入容器本身的writer。您需要类似以下代码的东西-基于文件创建一个“常规”文本编写器，然后基于该文件创建一个

JsonWriter

const string JSON = "{\"ArrayToManipulate\":[{\"Name\":\"Value\"},{\"Name\":\"value\"}]}";
var reader = new StringReader(JSON);
JContainer o = (JObject)JToken.ReadFrom(new JsonTextReader(reader));
JArray x = (JArray)o["ArrayToManipulate"];
ContentObject newObject = new ContentObject() { Name = "Value" };
JToken tokenToAdd = JToken.Parse(JsonConvert.SerializeObject(newObject, Formatting.Indented));
x.Add(tokenToAdd);
JsonSerializer jSerializer = new JsonSerializer();
jSerializer.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
using (var w = File.CreateText(@"C:\temp\a.json"))
{
    using (var jw = new JsonTextWriter(w))
    {
        jSerializer.Serialize(jw, o);
    }
}

如何从a.json文件**反序列化？

const string JSON = "{\"ArrayToManipulate\":[{\"Name\":\"Value\"},{\"Name\":\"value\"}]}";
var reader = new StringReader(JSON);
JContainer o = (JObject)JToken.ReadFrom(new JsonTextReader(reader));
JArray x = (JArray)o["ArrayToManipulate"];
ContentObject newObject = new ContentObject() { Name = "Value" };
JToken tokenToAdd = JToken.Parse(JsonConvert.SerializeObject(newObject, Formatting.Indented));
x.Add(tokenToAdd);
JsonSerializer jSerializer = new JsonSerializer();
jSerializer.Converters.Add(new Newtonsoft.Json.Converters.StringEnumConverter());
using (var w = File.CreateText(@"C:\temp\a.json"))
{
    using (var jw = new JsonTextWriter(w))
    {
        jSerializer.Serialize(jw, o);
    }
}
