Windows Phone 8 Silverlight JSON Deserealize

Question

我想解析Windows Phone 8.1 Silverlight項目中的一些json數據。我創建了類並反序列化了對象。每次它返回空值。我在哪裏做錯了？在此先感謝...

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

看起來你發佈你的JSON到http://json2csharp.com/和提供使用的類 - - 目前很好。但是，然後你將它們嵌套在一些外部類Zwave中，並試圖反序列化，這是不正確的。你需要做的：

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

或者更好的是，從Zwave容器類中刪除，並做

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

接下來，你的JSON包含"device"對象的數組 - 10 - 事實上這得到反序列化爲List<Device>。所以，如果你想他們的名字，你需要做的：

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

這給：

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