Json.Net - 序列化不带引号的属性名称

问题描述

我正在尝试让 Json.Net 序列化不带引号的属性名称，并且发现很难在 Google 上找到文档.我该怎么做?

I'm trying to get Json.Net to serialise a property name without quote marks, and finding it difficult to locate documentation on Google. How can I do this?

它在大型 Json 渲染的很小一部分中，所以我更喜欢添加一个属性属性，或者覆盖类上的序列化方法.

It's in a very small part of a large Json render, so I'd prefer to either add a property attribute, or override the serialising method on the class.

目前，它呈现如下:

"event_modal":
{
    "href":"file.html",
    "type":"full"
}

我希望让它呈现如下:(href 和 type 没有引号)

And I'm hoping to get it to render like: (href and type are without quotes)

"event_modal":
{
    href:"file.html",
    type:"full"
}

来自班级:

public class ModalOptions
{
    public object href { get; set; }
    public object type { get; set; }
}

推荐答案

这是可能的，但 我不建议这样做，因为它会产生无效的 JSON，正如 Marcelo 和 Marc 在他们的评论中指出的那样.

It's possible, but I advise against it as it would produce invalid JSON as Marcelo and Marc have pointed out in their comments.

使用 Json.NET 库，您可以按如下方式实现:

Using the Json.NET library you can achieve this as follows:

[JsonObject(MemberSerialization.OptIn)]
public class ModalOptions
{
    [JsonProperty]
    public object href { get; set; }

    [JsonProperty]
    public object type { get; set; }
}

当序列化对象时，使用 JsonSerializer 类型而不是静态 JsonConvert 类型.

When serializing the object use the JsonSerializer type instead of the static JsonConvert type.

例如:

var options = new ModalOptions { href = "file.html", type = "full" };
var serializer = new JsonSerializer();
var stringWriter = new StringWriter();
using (var writer = new JsonTextWriter(stringWriter))
{
    writer.QuoteName = false;
    serializer.Serialize(writer, options);            
}
var json = stringWriter.ToString();

这将产生:

{href:"file.html",type:"full"}

如果您设置了 JsonTextWriter 实例的 QuoteName 属性为 false 将不再引用对象名称.

If you set the QuoteName property of the JsonTextWriter instance to false the object names will no longer be quoted.
