將Json List反序列化為C＃List對象

Question

我有返回json字符串的類，但我想將其反序列化為C＃列表對象。 我當前的代碼如下所示

public class JsonBuilder
    {
        public static string BuildJson(DateTime fromDate, DateTime toDate)
        {
            var list = new List<dynamic>();

           // create list with json object from service

            var jsonObjList = JsonConvert.SerializeObject(list);
            var des = (List<JsonObject>)JsonConvert.DeserializeObject(jsonObjList, typeof(List<JsonObject>));

            return JsonConvert.SerializeObject(list);
        }

嘗試反序列化“序列化” json字符串時引發的異常

An exception of type 'Newtonsoft.Json.JsonSerializationException' occurred in Newtonsoft.Json.dll but was not handled in user code

Additional information: Error converting value 


InnerException:

{"Could not cast or convert from System.String to MvcWebApp.Models.JsonObject."}

Answer 1

您是否嘗試過：

var des = (List<DeserializeObjects>)JsonConvert.DeserializeObject(jsonObjList, jsonObjList.GetType()));

或這個：

var des = (List<DeserializeObjects>)JsonConvert.DeserializeObject(jsonObjList, typeof(List<dynamic>));

否則，這篇文章也可以幫助您實現目標：

使用Json.net將JSON對象反序列化為動態對象

Answer 2

嘗試這個

 var jsonObjList = JsonConvert.SerializeObject(list);
 dynamic resultList = JsonConvert.DeserializeObject(jsonObjList);

Answer 3

我會嘗試這class

public class Author
{
    public int id { get; set; }
    public string slug { get; set; }
    public string name { get; set; }
    public string first_name { get; set; }
    public string last_name { get; set; }
    public string nickname { get; set; }
    public string url { get; set; }
    public string description { get; set; }
}

public class CustomFields
{
    public List<string> tags { get; set; }
}

public class Post
{
    public int id { get; set; }
    public string type { get; set; }
    public string slug { get; set; }
    public string url { get; set; }
    public string status { get; set; }
    public string title { get; set; }
    public string title_plain { get; set; }
    public string content { get; set; }
    public string excerpt { get; set; }
    public string date { get; set; }
    public string modified { get; set; }
    public List<object> categories { get; set; }
    public List<object> tags { get; set; }
    public Author author { get; set; }
    public List<object> comments { get; set; }
    public List<object> attachments { get; set; }
    public int comment_count { get; set; }
    public string comment_status { get; set; }
    public CustomFields custom_fields { get; set; }
}

public class YourObject
{
    public string status { get; set; }
    public int count { get; set; }
    public int count_total { get; set; }
    public int pages { get; set; }
    public List<Post> posts { get; set; }
}

然后，您使用以下方法反序列化：

var yourObject = JsonConvert.DeserializeObject<YourObject>(json);
