[英]Convert JSON array to a c# object collection
我有一个如下所示的JSON,
[
{
"document":
{
"createdDate":1476996267864,
"processedDate":1476996267864,
"taxYear":"2015",
"type":"user_document"
}
},
{
"document":
{
"createdDate":1476998303463,
"processedDate":0,
"taxYear":"2015",
"type":"user_document"
}
}
]
我需要将其转换为ac#对象。 我的对象类型如下-
public class UserDocument
{
[JsonProperty(PropertyName = "type")]
public string type { get; set; }
[JsonProperty(PropertyName = "taxYear")]
public string taxYear { get; set; }
[JsonProperty(PropertyName = "createdDate")]
public string createdDate { get; set; }
[JsonProperty(PropertyName = "processedDate")]
public string processedDate { get; set; }
}
我正在使用下面的代码反序列化json,但是所有UserDocument属性均为null
var test = JsonConvert.DeserializeObject<List<UserDocument>>(jsonString);
为什么我所有的UserDocument属性都为null,这怎么了? 我没有任何错误。
您还可以建议一个将CouchBase查询结果转换为.net对象的好例子。
似乎您的json格式不正确。 如果我说你的json就像
[
"document":
{
"createdDate":1476996267864,
"processedDate":1476996267864,
"taxYear":"2015",
"type":"user_document"
},
"document":
{
"createdDate":1476998303463,
"processedDate":0,
"taxYear":"2015",
"type":"user_document"
}
]
然后创建一个像
public class Document
{
public UserDocument document {get;set;}
}
改变你的UserDocument
模型的createdDate
和processedDate
性能double
,因为它就像在你的JSON
public class UserDocument
{
[JsonProperty(PropertyName = "type")]
public string type { get; set; }
[JsonProperty(PropertyName = "taxYear")]
public string taxYear { get; set; }
[JsonProperty(PropertyName = "createdDate")]
public double createdDate { get; set; }
[JsonProperty(PropertyName = "processedDate")]
public double processedDate { get; set; }
}
然后反序列化
var test = JsonConvert.DeserializeObject<List<Document>>(jsonString);
这样的事情(使用Newtonsoft.Json.Linq):
var documents = JArray.Parse(json).Select(t => t["document"].ToObject<UserDocument>());
