xml:
http://wsf.cdyne.com/WeatherWS/Weather.asmx/GetCityWeatherByZIP?ZIP=48183
これが私のコードです:
    private void GetWeather()
    {
        WebClient web = new WebClient();
        web.DownloadStringCompleted += new DownloadStringCompletedEventHandler(web_DownloadStringCompleted);
        string uriAddr = "http://wsf.cdyne.com/WeatherWS/Weather.asmx/GetCityWeatherByZIP?ZIP=48183";
        web.DownloadStringAsync(new Uri(uriAddr));
    }
    void web_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
    {
        if (e.Error != null)
        {
            MessageBox.Show("error");
        }
        XElement XmlWeather = XElement.Parse(e.Result);
        foreach (var item in XmlWeather.Descendants("WeatherReturn"))
        {
            // code to get element info
        }
    }
foreachステートメントの中に入ることすらできません。助言がありますか?
