Question

我使用asp.net mvc4和newtonsoft.json。我有来自服务器的响应，并试图去实现它，但有一个错误。代码和错误在底部。有人能帮助我吗？

{"response":[208212605,223947262]}

var friends = JsonConvert.DeserializeObject<List<VkMutualFriends>>(response);

[JsonObject]
    public class VkMutualFriends {
        [JsonProperty("response")]
        public int UserId { get; set; }
    }



    Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 
    'System.Collections.Generic.List`1[SocialAnalytics.Models.ViewModel.VkMutualFriends]' 
    because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the 
deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, 
not a collection type like an array or List<T>) that can be deserialized from a JSON object. 
JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
        Path 'response', line 1, position 12.

该对象包含一个整数数组，但您要转换为单个int。因此错误。

尝试类似

的内容

[JsonProperty("response")]
public int[] UserIds { get; set; }
