问题 I want to convert a Json string to an Object in C#. the string is like this: {"dealName":"name1","properties":{"a":"1", "b":"2"}} I define the class like this: public class DealInfo { public string dealName; public Dictionary<string, string> properties; } And I use this code to convert: DealInfo dl = JsonConvert.Import(typeof(DealInfo), jsonString) as DealInfo; I found it just converted the dealName field, but the properties count is 0. So, what's the problem? How to fix it? Many thanks! 回答1:
