I'm trying to read values from System.Web.Helpers.DynamicJsonObject. I can see the values in the debugger but I can't figure out how to access them. I have tried this
我正在尝试从System.Web.Helpers.DynamicJsonObject中读取值。我可以在调试器中看到这些值，但我无法弄清楚如何访问它们。我试过这个
item.GetType().GetProperty("batch_id").GetValue(item, null);
item.GetType（）。GetProperty（“batch_id”）。GetValue（item，null）;
but when I try that I get this response in the debugger "item.GetType().GetProperty("batch_id")' is null"
但是当我尝试在调试器中得到这个响应“item.GetType（）。GetProperty（”batch_id“）'为null”
I have attached a picture from my solution

It is dynamic so you can just do:
这是动态的，所以你可以这样做：
string batchId = item.batch_id;
If for some reason you have the property name in a string, and don't know it at compile time, the indexing operator will work:
如果由于某种原因，您在字符串中具有属性名称，并且在编译时不知道它，则索引操作符将起作用：
string value = item["batch_id"];

Try enumerating the values DynamicJsonObject.GetDynamicMemberNames Method. It returns an IEnumerable of string.
尝试枚举值DynamicJsonObject.GetDynamicMemberNames方法。它返回一个IEnumerable字符串。

It doesn't work because they are fields, not properties. And, yeah, it is dynamic, so you can use just item.batch_id.
它不起作用，因为它们是字段，而不是属性。而且，是的，它是动态的，所以你可以只使用item.batch_id。
