Xamarin.Forms将json反序列化为对象 [英] Xamarin.Forms deserialising json to an object

问题描述

var myObjectList = (List<MyObject>)JsonConvert.DeserializeObject(strResponseMessage, typeof(List<MyObject>));

当JSON具有以下格式时，以上方法可将JSON字符串反序列化为自定义对象列表

the above works to deserialise a JSON string to a list of custom objects when the JSON has the following format

[
   {
     "Name": "Value"
   },
   {
     "Name": "Value"
   },
   {
     "Name": "Value"
   },
   "Name": "Value"
   }
]

这种格式时，我不知道该怎么做

I don't know how to do the same when the format is like this

{
    "ReturnedData" : [
       {
         "Name": "Value"
       },
       {
         "Name": "Value"
       },
       {
         "Name": "Value"
       },
       "Name": "Value"
       }
    ]

}

我可以得到这样的数据

JObject information = JObject.Parse(strResponseMessage);
foreach (dynamic data in information)
{
   //convert to object here
}

并且适用于Android，但由于出现错误，您似乎无法为iOS使用动态"类型:

and that works for Android but it seems that you cannot use a type of 'dynamic' for iOS as I get the error:

Object type Microsoft.CSharp.RuntimeBinder.CSharpInvokeMemberBinder cannot be converted to target type: System.Object[]

将第二个JSON字符串转换为第一个JSON缺少什么步骤?

What step am I missing to convert the second JSON string to the first?

推荐答案

感谢您的答复-我能够按照以下说明解决问题

Thanks for your replies - I was able to solve it as follows

JObject information = JObject.Parse(strResponseMessage);

string json = JsonConvert.SerializeObject(strResponseMessage["ReturnedData "]);

var myObjectList = (List<MyObject>)JsonConvert.DeserializeObject(json , typeof(List<MyObject>));

完美工作！
