我有以下json字符串:
{"Visits":[true,"DockedOnly","leftZone","0","500",0,0,0],
"Weather":[true,"DockedOnly","leftZone","0","0",0,0,1],
"ContactUs":[true,"DockedOnly","leftZone","0","317",0,0,2],
"Birthdays":[true,"DockedOnly","middleZone","0","0",0,0,0],
"Reminders":[true,"DockedOnly","middleZone","0","145",0,0,1],
"Messages":[true,"DockedOnly","middleZone","0","0",0,0,2],
"Availability":[true,"DockedOnly","middleZone","0","0",0,0,3],
"Settings":[false,"DockedOnly","leftzone","0","155",0,0,0]}
无论如何反序列化为以下内容?
[Serializable]
public class WidgetProps
{
public bool Visible { get; set; }
public string DockState { get; set; }
public string Zone { get; set; }
public string Top { get; set; }
public string Left { get; set; }
public int UnusedA { get; set; }
public int UnusedB { get; set; }
public int Position { get; set; }
}
[Serializable]
public class WidgetLayout
{
public WidgetProps Visits { get; set; }
public WidgetProps Weather { get; set; }
public WidgetProps ContactUs { get; set; }
public WidgetProps Birthdays { get; set; }
public WidgetProps Reminders { get; set; }
public WidgetProps Messages { get; set; }
public WidgetProps Availability { get; set; }
public WidgetProps Settings { get; set; }
}
或
public class Widget
{
public string WidgetName { get; set; }
public WidgetProps props { get; set; }
}
List<Widget> MyWidgets;
我获得了json字符串,所以我无法改变它给我的方式,但也许我可以在得到它之后修补它以便它可以工作。
我试过了:
string s = "{\"Visits\":[true,\"DockedOnly\",\"leftZone\",\"0\",\"500\",0,0,0],\"Weather\":[true,\"DockedOnly\",\"leftZone\",\"0\",\"0\",0,0,1],\"ContactUs\":[true,\"DockedOnly\",\"leftZone\",\"0\",\"317\",0,0,2],\"Birthdays\":[true,\"DockedOnly\",\"middleZone\",\"0\",\"0\",0,0,0],\"Reminders\":[true,\"DockedOnly\",\"middleZone\",\"0\",\"145\",0,0,1],\"Messages\":[true,\"DockedOnly\",\"middleZone\",\"0\",\"0\",0,0,2],\"Availability\":[true,\"DockedOnly\",\"middleZone\",\"0\",\"0\",0,0,3],\"Settings\":[false,\"DockedOnly\",\"leftzone\",\"0\",\"155\",0,0,0]}}";
var sd = new JavaScriptSerializer().Deserialize < List<Widget>>(s);
和
var sd = new JavaScriptSerializer().Deserialize < WidgetLayout >(s);

这不起作用,因为您尝试将数组反序列化为对象。 json.NET反序列化器无法进行转换。
因为你的json数组中有多种类型,你必须反序列化为最小的公分母,在本例中为object
。从那里我建议编写一个方法,将每个索引分配给它在WidgetProps中的相应属性。
所以基本上,定义这个构造函数;
public WidgetProps(object[] props)
{
Visible = (bool)props[0];
DockState = (string)props[1];
// ext
}
我会像WidgetDirty
课那样对我进行初步的消毒。从那里你可以创建WidgetLayout
的新实例,通过实例化它的每个属性,如myWidgetLayoutInstance.Visits = new WidgetProp(myWidgetDirtyInstance.Visits);
我可能会在WidgetLayout
构造函数中隐藏这个混乱,其中WidgetDirty
为dynamic
它只是arg。
是的,这很恶心......但我不知道任何真正的替代品,因为json的设计与C#语言不太相容。如果您对此非常感兴趣,我可能会查看{{1}}类型。我没有在C#中使用它,也许永远都不会,但我知道用PHP这样的动态语言反序列化就不会有麻烦了。

这不起作用,因为数组通常不会反序列化为对象。如果可能的话,我认为你应该修复JSON。如果您不能这样做,并且您正在使用JSON.NET,则可以为JsonConverter
创建WidgetProps
,以便手动将数组转换为对象:
class WidgetPropsConverter : JsonConverter
{
public override void WriteJson(
JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotSupportedException();
}
public override object ReadJson(
JsonReader reader, Type objectType, object existingValue,
JsonSerializer serializer)
{
var array = serializer.Deserialize<object[]>(reader);
return new WidgetProps
{
Visible = (bool)array[0],
DockState = (string)array[1],
Zone = (string)array[2],
Top = (string)array[3],
Left = (string)array[4],
Position = (int)(long)array[7]
};
}
public override bool CanConvert(Type objectType)
{
return objectType == typeof(WidgetProps);
}
}
然后你会像这样使用它:
var result = JsonConvert.DeserializeObject<WidgetLayout>(
jsonString, new WidgetPropsConverter());
