Windows Phone 8 Silverlight JSON取消密封

Question

我想在我的Windows Phone 8.1 Silverlight项目中解析一些json数据。我创建了类并反序列化对象。每次返回空值。我哪里做错了？提前感谢。。。

JSON-

功能

HttpClient httpClient = new HttpClient();
var json = await httpClient.GetStringAsync(new Uri("http://xx.xxx.xxx.xxx:xxxx/data_request?id=lu_sdata"));
Zwave returned=JsonConvert.DeserializeObject<Zwave>(json);
var listed = returned.device.name;

Answer 1

看起来您将JSON发布到http://json2csharp.com/并使用了提供的类——到目前为止还不错。但随后您将它们嵌套在某个外部类Zwave中，并试图对其进行反序列化，这是不正确的。你需要做：

var returned = JsonConvert.DeserializeObject<Zwave.RootObject>(json);

或者更好的是，将它们从Zwave容器类中删除，然后进行

var returned = JsonConvert.DeserializeObject<RootObject>(json);

接下来，JSON包含一个"device"对象数组——实际上是10个——它们被反序列化为List<Device>。所以，如果你想要他们所有的名字，你需要做：

var listed = returned.devices.Select(d => d.name).ToList();

它给出：

["Duman Sensoru","Hareket Sensoru","Isik Sensoru","Kapı Kilidi","Nem Sensoru","On/Off Switch","Pencere&Kapi Sensoru","Priz","Temperature Sensor","Termometre"]
