Windows Phone 8 Silverlight JSON 反序列化

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了对象。每次它 returns 空值。我哪里做错了？提前致谢...

JSON

Answer 1

您似乎已将 JSON 发布到 http://json2csharp.com/ 并使用了所提供的 classes -- 到目前为止还不错。但是你将它们嵌套在一些外部 class Zwave 中并试图反序列化它，这是不正确的。你需要做的：

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

或者更好的是，将它们从 Zwave 容器中移除 class 并执行

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

接下来，您的 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();

给出：

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