我试图从this api抓住高点和低点，我能够获得高点，但无法弄清楚要做什么来获得低点，这是第二个发生了一个名为＆＃34; fahrenheit＆＃34;的项目，我怎么能用我用来获得High的相同方法呢？
if (xmlForecast.Name == "fahrenheit" && i == 0)
{
i++;
xmlHigh = xmlForecast.ReadString();
}
答案 0 :(得分：1)
由于您需要使用XML响应的解决方案，因此它是：
首先，您需要创建代表XML响应的类。
1 2 3
1 2 3
2 1 4 5
3 1
4 2 1
5 2
其次，您需要将XML反序列化为[XmlRoot("response")]
public class Response
{
[XmlElement("version")]
public string Version { get; set; }
[XmlElement("termsofService")]
public string TermsOfService { get; set; }
[XmlElement("features")]

}
Response我正在使用using (HttpClient client = new HttpClient())
{
using (var stream = await client.GetStreamAsync("http://api.wunderground.com/api/ea4bb7e7839782da/forecast/q/CA/San_Francisco.xml"))
{
var serializer = new XmlSerializer(typeof(Response));
var response = (Response)serializer.Deserialize(stream);
var simpleForecast = response.Forecast.SimpleForecast;
var forecastDays = simpleForecast.ForecastDays;
var latestForecastDay = forecastDays.Last();
var latestHighFahrenheit = latestForecastDay.High.Fahrenheit;
var latestLowFahrenheit = latestForecastDay.Low.Fahrenheit;
}
}
，但您也可以使用更新的XmlSerializer。如果您决定使用DataContractSerializer，请注意，您需要将DataContractSerializer属性替换为XmlElement和DataContract。
注意：我故意添加了一些不必要的步骤和变量声明，因此您可以清楚地看到这里发生了什么。
