JObject SelectToken 解析路径索引器时出现意外字符
JObject SelectToken Unexpected character while parsing path indexer
我需要解析 API json 响应以提取特定值。直到今晚，这种方法对我来说一直很有效，没有问题。尝试执行此代码时：
JObject oR = JObject.Parse(response2.Content);
if (oR.SelectToken("[response][0][assignment][current][channelId]") != null)
{
ChannelId = oR.SelectToken("[response][0][assignment][current][channelId]").ToString();
}
我收到此错误：
Unexpected character while parsing path indexer: r
这是我正在尝试解析的 api 的完整 json 响应：

不幸的是，我无法控制从网络服务 API 返回的 json。我能找到的最好的结果是 json 键之一有问题，但我似乎无法弄清楚如何修复它或解释它。
在此先感谢您的帮助。
正确的 JSONPath 语法是：
response[0].assignment.current.channelId
...或使用 enquoted 属性 名称：
['response'][0]['assignment']['current']['channelId']
我个人更喜欢前一种语法，因为它更清晰易读。
此外，您的程序也很低效，因为您正在评估 JSONPath 两次。而是使用 C# 的 is var 运算符来存储结果：
JObject oR = JObject.Parse(response2.Content);
if (oR.SelectToken("response[0].assignment.current.channelId") is JToken channelIdToken)
{
this.ChannelId = channelIdToken.ToString();
}
