显示天气

调用接口，写个webserver,再调用webserver

接口：http://webservice.webxml.com.cn/WebServices/WeatherWS.asmx  

写webserver:

  应用（动态调用webserver）：

<add key="CityCode" value="2408"/>

  <add key="SMSServices" value="SMSServices.asmx"/>

  public void GetWeather()
    {
        string citycode = ConfigurationManager.AppSettings["CityCode"];
        string servicename = ConfigurationManager.AppSettings["WeatherServices"]; //webserver名字
        object[] args = new object[1]; //参数
        args[0] = citycode;
        string mes = "";
        string date = DateTime.Now.ToString("M月d日");

        string[] ss = (string[])Common.Lib.WebServiceHelper.InvokeWebService(servicename, "WeatherOfJiangMen", args); //动态调用
        for (int i = 7; i < ss.Length; i++)
        {
            string str = ss[i];
            bool bl = str.Contains(date);
            if (bl == true)
            {
                str = str.Replace(date, "");
                mes = date + "  江门天气:" + str + " " + ss[i + 1] + "  " + ss[i + 2];
                lblWeather.Text = mes;
                return;
            }

        }
        lblWeather.Text = "";
    }
