public partial class Testing : System.Web.UI.Page 
    { 
     weather.WeatherForecastServiceClient ws = new weather.WeatherForecastServiceClient(); 
     protected void Page_Load(object sender, EventArgs e) 
     { 
      SortedDictionary<string, string> objDic = new SortedDictionary<string, string>(); 
      foreach (CultureInfo ObjectCultureInfo in CultureInfo.GetCultures(CultureTypes.SpecificCultures)) 
      { 
       RegionInfo objRegionInfo = new RegionInfo(ObjectCultureInfo.Name); 
       if (!objDic.ContainsKey(objRegionInfo.EnglishName)) 
       { 
        objDic.Add(objRegionInfo.EnglishName, ObjectCultureInfo.Name); 
       } 
      } 
     foreach (KeyValuePair<string, string> val in objDic) 
     { 
      Country.Items.Add(new ListItem(val.Key, val.Value)); 
     } 

    } 

    protected void callwebservice_Click(object sender, EventArgs e) 
    { 

      Result.Text = "Result" + ws.GetForecastByCity(City.SelectedItem.ToString(), Country.SelectedItem.ToString()); 

    } 

    protected void Country_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     string[] cities = ws.GetCitiesByCountry(Country.SelectedItem.ToString()); 
     City.DataSource = cities; 
     City.DataBind(); 
    } 
}

您正確實施服務。您可以運行GetCitiesByCountry（它會返回一個城市列表）來確認。只是方法GetForecastByCity目前沒有工作。

嘗試使用these APIs來代替。
