ServiceStack:新手反序列化Json

Question

我正在编写一个helloworld MonoTouch应用程序来使用ServiceStack来使用Json并且有两个相关的问题.

我的测试json是:https://raw.github.com/currencybot/open-exchange-rates/master/latest.json

在我的DTO对象中,如何使用映射到json元素的不同命名属性？

我有这个,它有效,但我想使用不同的字段名称？

public class Currency
{
    public string disclaimer { get; set; }
    public string license { get; set; }
    public string timestamp  { get; set; }
}

如何从这个json中添加我的DTO中的Rates集合？

"rates": {
    "AED": 3.6731,
    "AFN": 48.330002,
    "ALL": 103.809998,
     ETC...

ServiceStack拥有一个非常棒的Fluent JSON Parser API,使您可以轻松地对现有模型进行操作,而无需使用"Contract"基本序列化.这应该让你开始:

public class Rates {
    public double AED { get; set; }
    public double AFN { get; set; }
    public double ALL { get; set; }
}

public class Currency {
    public string disclaimer { get; set; }
    public string license { get; set; }
    public string timestamp  { get; set; }
    public Rates CurrencyRates { get; set; }
}

...

var currency = new Currency();
currency.CurrencyRates = JsonObject.Parse(json).ConvertTo(x => new Currency{
    disclaimer   = x.Get("disclaimer"),
    license = x.Get("license"),
    timestamp = x.Get("timestamp"),
    CurrencyRates = x.Object("rates").ConvertTo(r => new Rates {
        AED = x.Get<double>("AED"),
        AFN = x.Get<double>("AFN"),
        ALL = x.Get<double>("ALL"),
    })
});
