如何将json属性反序列化为类属性？

我的JSON文件

[ { "amount":"1000000.0", "check_number":1, "payment_number":5, "attachments":[ { "id":5324, "url":"http://www.example.com/", "filename":"january_receipt_copy.jpg" } ] } ] 

我的class级档案

 public class Attachment { public int id { get; set; } public string url { get; set; } public string filename { get; set; } } public class AccountDetail { public string amount { get; set; } public int check_number { get; set; } public int payment_number { get; set; } } public class RootObject { public AccountDetail accountdetail{ get; set; } public List attachments { get; set; } } 

现在我想通过使用newtonsoft JSON反序列化将JSON文件的属性‘check_number’，’amount’等映射到accountdetail。

您需要以下两个类：

 public class Attachment { [JsonProperty("id")] public int Id { get; set; } [JsonProperty("url")] public string Url { get; set; } [JsonProperty("filename")] public string Filename { get; set; } } public class AccountDetails { [JsonProperty("amount")] public string Amount { get; set; } [JsonProperty("check_number")] public int CheckNumber { get; set; } [JsonProperty("payment_number")] public int PaymentNumber { get; set; } [JsonProperty("attachments")] public IList Attachments { get; set; } } 

通过定义上面的类，您可以反序列化您的json，如下所示：

 var accountsDetails = JsonConvert.DeserializeObject>(json);
