Question

首先我知道这个问题被问了好几百次，但我不知道我的问题是什么。

我试图使用NewtonSoft将json字符串反序列化为自定义对象。

var client = new RestClient(URL);
        var request = new RestRequest(Method.POST);
        request.RequestFormat = DataFormat.Json;
        request.AddJsonBody(retEmployeeFilters);
        var response = client.Execute(request);
        //Console.WriteLine(response.Content);
        return JsonConvert.DeserializeObject<RetrieveEmployeeResponse>(response.Content);

行

Console.WriteLine（response.Content）;

返回此json

{"response":[{"id":3,"name":"A","email":"sansdad32a.@ds.com","mobile_number":"41","address":"B","age":20,"role":"N","hiring_date":"2053-04-03","created_at":"2016-03-16 23:49:15","updated_at":"2016-03-16 23:49:15"},{"id":4,"name":"B","email":"sansda32d32a.@ds.com","mobile_number":"41321","address":"Q","age":20,"role":"C","hiring_date":"2053-04-03","created_at":"2016-03-16 23:49:24","updated_at":"2016-03-16 23:49:24"}]}

这里是RetrieveEmployeeResponse类

class RetrieveEmployeeResponse 

{
    public List<Employee> response { get; set; }
    public String success { get; set; }
}

员工类

class Employee
{
    public int id {get;set;}
    public String name {get;set;}
    public String email {get;set;}
    public String mobile_number {get;set;}
    public int age {get;set;}
    public String address {get;set;}
    public String role {get;set;}
    public String hiring_date {get;set;}
}

是我做的一切吗？

调试此处返回的对象

return JsonConvert.DeserializeObject<RetrieveEmployeeResponse>(response.Content);

有response = null和success = null

任何帮助？

Answer 1

通过评论中的讨论，以下代码修复了问题，但原始问题的内容仍然不清楚。如果有明确的话，我会更新这个答案。

将行return JsonConvert.DeserializeObject<RetrieveEmployeeResponse>(response.Content);更改为以下内容，解决了返回对象中null属性的问题。

var tempStr = response.Content;
var temp = JsonConvert.DeserializeObject<RetrieveEmployeeResponse>(tempStr);
return temp;

您应该将收到的json响应反序列化为

  string responseJson="{\"response\":[{\"id\":3,\"name\":\"A\",\"email\":\"sansdad32a.@ds.com\",\"mobile_number\":\"41\",\"address\":\"B\",\"age\":20,\"role\":\"N\",\"hiring_date\":\"2053-04-03\",\"created_at\":\"2016-03-16 23:49:15\",\"updated_at\":\"2016-03-16 23:49:15\"},{\"id\":4,\"name\":\"B\",\"email\":\"sansda32d32a.@ds.com\",\"mobile_number\":\"41321\",\"address\":\"Q\",\"age\":20,\"role\":\"C\",\"hiring_date\":\"2053-04-03\",\"created_at\":\"2016-03-16 23:49:24\",\"updated_at\":\"2016-03-16 23:49:24\"}]}\r\n";

  return JsonConvert.DeserializeObject<RetrieveEmployeeResponse>(responseJson);

你的json没有任何成功字符串，这就是反序列化后它为空的原因。

使用NewtonSoft将JSON反序列化为.net不同的对象
