反序列化LinkedIn个人资料Json？

Question

我试图反序列化，我从LinkedIn的Javascript API得到一个JSON对象：

{"_key":"~","educations":{"_total":2,"values":[{"degree":"Bachelor of Science (BSc)","endDate":{"year":2004}, 
"fieldOfStudy":"Computer Software Engineering","id":134450447,"schoolName":"Bristol University"," 
startDate":{"year":2009}},{"id":143651018,"schoolName":"University of Kingston"}]},"emailAddress": 
"test@test.com","firstName":"Robert","lastName":"Matthews"} 

我写了一个自定义类来存储这些值，并使用反序列化它们Json.NET：

[Serializable] 
    public class LinkedInUserData { 

    [JsonProperty(PropertyName = "emailAddress")] 
    public string EmailAddress { get; set; } 

    // other properties cut out for simplicity 

    [JsonProperty(PropertyName = "educations")] 
    public Educations Educations { get; set; } 
    } 

    [Serializable] 
    public class Educations { 

    [JsonProperty(PropertyName = "_total")] 
    public string Total { get; set; } 

    [JsonProperty(PropertyName = "values")] 
    public Values Values { get; set; } 
    } 

    [Serializable] 
    public class Values { // cut down for simplicity 

    [JsonProperty(PropertyName = "degree")] 
    public string Degree { get; set; } 

    } 

LinkedInUserData linkedData = JsonConvert.DeserializeObject<LinkedInUserData>(profile); 

我能够在单个对象（无阵列等）转换没有任何问题，但我被陷在值对象的教育，并出现以下错误信息：

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'Data.Values' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly. To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array. Path 'educations.values', line 1, position 47.

我已经尝试将Educations中的Values对象更改为字符串数组，但没有运气。有没有什么办法可以将Json中的值反序列化到我的自定义类中，还是只能沿着字符串数组获取某些内容？

编辑 - 清单产品（值）以下错误：

Error reading string. Unexpected token: StartObject. Path 'educations.values[0].endDate', line 1, position 96.

编辑2 - 好吧，我现在就买下，列表（值）所做的工作，然后将其绊倒在StartDate和EndDate上，因为它们本身就是对象，而且我将它们设置为strings。我很努力去理解Json字符串，但Link2CSharp帮助我解决了这个问题。

我相信你需要根据json重新调整你的类。你可以试着用Json生成C＃类，使用json2csharp（如果你想自动创建针对json的C＃类，这是一个很好的资源）。以下是它给出的结构。你可以使用JSON.Net来获取对象。

public class EndDate 
{ 
    public int year { get; set; } 
} 

public class StartDate 
{ 
    public int year { get; set; } 
} 

public class Value 
{ 
    public string degree { get; set; } 
    public EndDate endDate { get; set; } 
    public string fieldOfStudy { get; set; } 
    public int id { get; set; } 
    public string schoolName { get; set; } 
    public StartDate __invalid_name__ 
startDate { get; set; } 
} 

public class Educations 
{ 
    public int _total { get; set; } 
    public List<Value> values { get; set; } 
} 

public class RootObject 
{ 
    public string _key { get; set; } 
    public Educations educations { get; set; } 
    public string emailAddress { get; set; } 
    public string firstName { get; set; } 
    public string lastName { get; set; } 
}
