Weather Webpart by using Yahoo Service in Share Point

Hello folks,

In a following post we will see how to build Weather Report  by using Yahoo Web service.
We need to pass city codes as a Parameter.

Please find the below code snippet to build Weather Webpart. below code is self explanatory.

   DataTable dtWeather = new DataTable();

   // Adding columns to data table

   dtWeather.Columns.Add("ImgSrc");

   dtWeather.Columns.Add("Place");

   dtWeather.Columns.Add("temp");

   try

   {

      // url to get the weather from yahoo web service

    if (!string.IsNullOrEmpty(strCityCodes))

     {

      url = "http://weather.yahooapis.com/forecastrss?p=" + strCityCode;

                             

      DataSet ds = new DataSet();

      XmlDocument xmlDoc = new XmlDocument();

      HttpWebRequest wRequest = (HttpWebRequest)WebRequest.Create(url);

      HttpWebResponse wResponse = (HttpWebResponse)wRequest.GetResponse();

      try

        {

            // Check when no internet

         if (wResponse.StatusCode == HttpStatusCode.OK)

          {

           StreamReader StreamHandler = new                              System.IO.StreamReader(wResponse.GetResponseStream());

           xmlDoc.LoadXml(StreamHandler.ReadToEnd());

           XmlNodeReader data = new XmlNodeReader(xmlDoc);

           ds.ReadXml(data);

         ImageURL1 = ds.Tables["item"].Rows[0]       ["description"].ToString().Substring(11).Split('"');

      if(string.IsNullOrEmpty(Convert.ToString(ImageURL1)))

      {

      }

     else

     {

      Weather = ds.Tables["condition"].Rows[0]["temp"].ToString();
     }

    if (string.IsNullOrEmpty(Weather))

   {

       WeatherAni.Visible = false;

       WeatherWebPart.Visible = false;

       lblError.Visible = true;

       lblError.Text = "There is No Data for the Weather from Yahoo Web Service";

    }

   else

    {

     Double temp = Convert.ToDouble(Weather);

     int ctemp = (int)((temp - 32) * 5 / 9);

     String Weather1 = string.Format("{0}° C", ctemp);

     DataRow dtlistRow = dtWeather.NewRow();

     dtlistRow["ImgSrc"] = Convert.ToString(ImageURL1[0]);

      if (!string.IsNullOrEmpty(strDisplayName[code]))

      {

       dtlistRow["Place"] = Convert.ToString(strDisplayName[code]);

      }

      else

      {

       dtlistRow["Place"] = string.Empty;

      }

     dtlistRow["temp"] = Convert.ToString(Weather1);

    dtWeather.Rows.Add(dtlistRow);

  }

  }

 }

 catch (Exception ex)

 {

 //Exception Handling

 }

 }

 if (dtWeather.Rows.Count > 0)

 {

  reptWeather.DataSource = dtWeather;

  reptWeather.DataBind();

  }

  else

  {

     //

  }

  
}

Thanks.
