问题 I have a JSON response (which I have no control over) similar to this: {"response":{ "a" : "value of a", "b" : "value of b", "c" : "value of c", ... }} Where: "a", "b", "c" are unknown names upfront. The number of items can vary. All I need at the end is an array of strings for all the values. Keeping the names is a bonus (Dictionary?) but I need to browse values by the order in which they appear. How would you achieve this using JSON.NET? 回答1: You can use the JObject class from the

问题 I'm using the custom JsonSerializer as mentioned in the Readme file in the RestSharp package.

To use Json.NET for serialization, copy the code from
