c#将类转换为json文件

我正在使用这个类：

 class message
    {
        public content Content { get; set; }
        public from From { get; set;  }
        public personalizations Personalizations { get; set; }
    }


    public class content
    {
        public string type = "text/html";
        public string value = "html";
    }

    public class from
    {
        public string email = "example@example.com";
        public string name = "example";

    }
    public class personalizations
    {
        public List<to> tos { get; set; }
    }
    public class to
    {
        public string subject { get; set; }
        public string email { get; set; }
    }

但我确实想要这种格式：

{
  "content": [
    {
      "type": "text/html", 
      "value": "Html"
    }
  ], 
  "from": {
    "email": "", 
    "name": ""
  }, 

  "personalizations": [
    {
      "subject": "",
      "to": [ { "email": "" }]
    },
    {
        "subject": "",
        "to": [{ "email": "" }]
    },
    {
        "subject": "",
        "to": [{ "email": "" }]
    }

    ]

}

如何将格式更改为最后一种格式

提前谢谢

编辑：

我想更改格式，而不是值 例如：

---

在上一个json示例中，我有一个personalization对象，其中包含多个json，但在第一个示例中，我只有一个对象

，根据您最近的评论，您希望更改输出格式。您可以通过将属性“publicstringsubject”从“to”类移动到“personalizations”类来实现这一点，如下所示：

顺便说一句，你应该看看

你可以把你想要的JSON复制到你的剪贴板上。然后，您可以从“编辑”菜单转到Visual Studio中的任何.cs文件，您可以展开“粘贴特殊”菜单。选择“将JSON粘贴为类”选项，您将得到以下结果：

public class Rootobject
{
    public Content[] content { get; set; }
    public From from { get; set; }
    public Personalization[] personalizations { get; set; }
}

public class From
{
    public string email { get; set; }
    public string name { get; set; }
}

public class Content
{
    public string type { get; set; }
    public string value { get; set; }
}

public class Personalization
{
    public string subject { get; set; }
    public To[] to { get; set; }
}

public class To
{
    public string email { get; set; }
}

null！=“

…请看@shurik您是对的。。。显然，OP知道如何从JSON构造类，以及如何将对象表示为单元素数组——重新打开并等待澄清它们到底有什么问题。是他试图处理的空值，还是JSON本身的结构？“个性化”在这两个示例中有不同的结构。@shurik不，我不是说值，而是说格式

{
  "content": [
    {
      "type": "text/html", 
      "value": "Html"
    }
  ], 
  "from": {
    "email": "", 
    "name": ""
  }, 

  "personalizations": [
    {
      "subject": "",
      "to": [ { "email": "" }]
    },
    {
        "subject": "",
        "to": [{ "email": "" }]
    },
    {
        "subject": "",
        "to": [{ "email": "" }]
    }

    ]

}

public class Rootobject
{
    public Content[] content { get; set; }
    public From from { get; set; }
    public Personalization[] personalizations { get; set; }
}

public class From
{
    public string email { get; set; }
    public string name { get; set; }
}

public class Content
{
    public string type { get; set; }
    public string value { get; set; }
}

public class Personalization
{
    public string subject { get; set; }
    public To[] to { get; set; }
}

public class To
{
    public string email { get; set; }
}
