创建不带数组缩进的JSON [英] Creating JSON without array indentation

问题描述

我通常会得到非常大的JSON，其中包含很多列表以及列表中的许多元素.我的目标是得到左边的结构，而不是右边的结构. 正确的结构是我从Newtonsoft得到的. 是否有另一个库可以让我像这样打印它?

I usually get very big JSON with a lot of lists and a lot of elements inside the lists. My goal is to get the left structure instead of the right one. The right structure is what I get from Newtonsoft. Is there another library that gives me the control to print it like this?

推荐答案

如果您将JsonTextWriter类子类化并重写WriteIndent方法，则可以使用Json.Net(又名Newtonsoft Json)获得所需的缩进:

You can get the indenting you want with Json.Net (a.k.a. Newtonsoft Json) if you subclass the JsonTextWriter class and override the WriteIndent method like this:

public class CustomJsonTextWriter : JsonTextWriter
{
    public CustomJsonTextWriter(TextWriter writer) : base(writer)
    {
    }

    protected override void WriteIndent()
    {
        if (WriteState != WriteState.Array)
            base.WriteIndent();
        else
            WriteIndentSpace();
    }
}

然后创建一个小的辅助方法，以使其易于使用自定义编写器:

Then create a small helper method to make it easy to use the custom writer:

public static class JsonHelper
{
    public static string SerializeWithCustomIndenting(object obj)
    {
        using (StringWriter sw = new StringWriter())
        using (JsonWriter jw = new CustomJsonTextWriter(sw))
        {
            jw.Formatting = Formatting.Indented;
            JsonSerializer ser = new JsonSerializer();
            ser.Serialize(jw, obj);
            return sw.ToString();
        }
    }
}
