使用 Json.Net 在 json 对象后丢弃垃圾字符

问题描述

我必须使用一个由愚蠢的猴子实现的所谓 Web 服务，它在正确的 Json 响应后返回一些垃圾.像这样的:

I have to consume a so called web service implemented by a dumb monkey which is returning some garbage after the proper Json response. Something like this:

{
  "Property1": 1,
  "Property2": 2,
  "Property3": 3
}<?xml version='1.0' ?>Maybe some other gibberish nonsense I wish to discard.

现在，我可以搜索 "<?xml" 并拆分，但我想知道是否可以使用流阅读器或其他东西来阅读最多关闭 } 然后丢弃其余部分.

Now, I could just search for "<?xml" and split, but I was wondering if I can use a stream reader or something to read up to the closing } and then discard the rest.

我正在使用 C# 和 Json.Net.

I'm using C# and Json.Net.

推荐答案

你也可以设置JsonSerializerSettings.CheckAdditionalContent = false 告诉序列化器忽略反序列化 JSON 对象结束后的任何内容:

You can also set JsonSerializerSettings.CheckAdditionalContent = false to tell the serializer to ignore any content after the end of the deserialized JSON object:

var result = JsonConvert.DeserializeObject<Dictionary<string, long>>(json, new JsonSerializerSettings { CheckAdditionalContent = false })

奇怪的是，尽管默认值似乎已经是 false，但还是有必要明确地执行此操作，因为 基础字段可以为空.

Oddly enough it is necessary to do this explicitly despite the fact that the default value seems to be false already, since the underlying field is nullable.
