Question

这是我第一次使用DataContractSerializer如果这个问题是基本的，请原谅我，但我似乎无法找到解决方案。

我已经设置了课程AuthTokenContract

[DataContract]
public class AuthTokenContract
{
    [DataMember(Name="token")]
    public string Token { get; set; }
}

我的方法是将JSON响应绑定到我的模型

public Guid GetAuthToken()
{
    var queryString = new Uri(String.Format("token?apiKey={0}", _apiKey), UriKind.Relative);
    var requestUrl = new Uri(_baseUrl, queryString);

    var contract = GetResponse<AuthTokenContract>(requestUrl);

    return Guid.NewGuid(); // Ignore
}

private TContractType GetResponse<TContractType>(Uri requestUrl) where TContractType : class 
{
    HttpWebRequest request = WebRequest.Create(requestUrl) as HttpWebRequest;
    using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
    {
        DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer(typeof(TContractType));
        object objResponse = jsonSerializer.ReadObject(response.GetResponseStream());
        return objResponse as TContractType;
    }
}

这是我从网址获得的回复：

{
    "result":
        {
            "token":"8D53ED8E-DE75-423B-AC76-DADEF7139D98"
        },
    "warnings":[]
}

但是，contract.Token始终是null。我知道它正在返回上面的JSON，但我无法正确翻译。有什么帮助吗？

将合同更改为

[DataContract]
public class AuthTokenContract
{
    [DataMember(Name = "result")]
    public Result result { get; set; }

    [DataMember(Name = "warnings")]
    public string[] Warnings { get; set; }
}

[DataContract]
public class Result
{
    [DataMember(Name = "token")]
    public string Token { get; set; }
}
