Question

我在使用C＃和asp.net

将Collection + JSON（http://amundsen.com/media-types/collection/format/）反序列化为对象时出现问题

JSON格式： { "collection": { "version": "1.0", "href": "http://www.example.com/api/", "links": [{ "href": "http://example.com/api/issues", "rel": "issuesLink", "name": "issuesLink", "render": "link", "prompt": "All issues ordered by number" }], "queries": [{ "href": "https:\/\/example.com\/api\/search\/{field}\/{value}", "rel": "searchByField", "name": "FieldSearch", "prompt": "Search by field", "data": [{ "name": "name", "value": "field" }, { "name": "value", "value": "" }] }] } }

我使用（或不使用）JSON.net没有任何问题，但无论如何都无法正确地反序列化。我有JSON

public class FPResponse
{
    [JsonProperty("collection")]
    //I have tried using List<string> too
    // public Billboard collection executes the code but returns null for o
    public string collection { get; set; }
}

public class Billboard
{
    [JsonProperty("version")]
    public string version { get; set; }

    [JsonProperty("href")]
    public string href { get; set; }

    [JsonProperty("links")]
    public IList<LinkSet> links { get; set; }
}

using (var reader = new StreamReader(dataStream))
{
    string rtn = reader.ReadToEnd(); //has the JSON string
    var o = JsonConvert.DeserializeObject<FPResponse>(rtn);
}

使用JSON.NET的错误：附加信息：读取字符串时出错。意外的令牌：StartObject。路径＆＃39;收集＆＃39;，第1行，第15位。

感谢您的帮助......

collection不是string

您的声明应如下：

public class Link
{
    public string href { get; set; }
    public string rel { get; set; }
    public string name { get; set; }
    public string render { get; set; }
    public string prompt { get; set; }
}

public class Datum
{
    public string name { get; set; }
    public string value { get; set; }
}

public class Query
{
    public string href { get; set; }
    public string rel { get; set; }
    public string name { get; set; }
    public string prompt { get; set; }
    public List<Datum> data { get; set; }
}

public class Collection
{
    public string version { get; set; }
    public string href { get; set; }
    public List<Link> links { get; set; }
    public List<Query> queries { get; set; }
}

public class FPResponse
{
    public Collection collection { get; set; }
}
