用匹配的花括号分割字符串的最佳方法

问题描述

我现在正在C#中工作，并且正在使用JSON.Net将JSON字符串解析为C#对象.我的问题的部分原因是我得到了一些像这样的字符串:

I'm working in C# right now and I'm using JSON.Net to parse json strings to well, C# objects. Part of my problem is that I'm getting some strings like this:

{"name": "John"}{"name": "Joe"}

当我尝试使用JsonConvert.DeserializeObject<>反序列化时，会引发异常.

When I try to deserialize with JsonConvert.DeserializeObject<>, it throws an exception.

我想知道将这个较大的字符串拆分为较小的json字符串的最佳方法是什么.

I'm wondering what would be the best way to split of this bigger string into smaller json strings.

我正在考虑遍历字符串并匹配级别0"的花括号.这似乎是个好主意吗?还是有更好的方法来做到这一点?

I was thinking about going through the string and matching curly braces of "level 0". Does this seem like a good idea? Or is there some better method to do this?

推荐答案

您可以将SupportMultipleContent标志设置为true的JsonTextReader来读取此非标准JSON.假设您有一个如下所示的类Person:

You can use a JsonTextReader with the SupportMultipleContent flag set to true to read this non-standard JSON. Assuming you have a class Person that looks like this:

class Person
{
    public string Name { get; set; }
}

您可以像这样反序列化JSON对象:

You can deserialize the JSON objects like this:

string json = @"{""name"": ""John""}{""name"": ""Joe""}";

using (StringReader sr = new StringReader(json))
using (JsonTextReader reader = new JsonTextReader(sr))
{
    reader.SupportMultipleContent = true;

    var serializer = new JsonSerializer();
    while (reader.Read())
    {
        if (reader.TokenType == JsonToken.StartObject)
        {
            Person p = serializer.Deserialize<Person>(reader);
            Console.WriteLine(p.Name);
        }
    }
}
