I would like to add an reference for WCF weather forecast webservice in my application.The thing is I have done everything correctly,but i am lacking somewhere else.It throws an Exception.The Exception message is in the bottom of this post.Somebody out there please help me to fix this.Unles or until fixing this i couln't move to the next phase.

我的源代码在这里：

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();
    }
}

这是我的例外

您已正确实施该服务。您可以通过运行来确认这一点GetCitiesByCountry（它将返回一个城市列表）。只是该方法GetForecastByCity目前不起作用。

请尝试使用这些 API中的任何一个。
