C# WinForm 访问webService天气预报

 private void button1_Click(object sender, EventArgs e)
        {
            Weather1.WeatherWebServiceSoap wt = new WebServiceTest.Weather1.WeatherWebServiceSoapClient("WeatherWebServiceSoap");

            string[] s = new string[30];

            s = wt.getSupportCity("山东");

            for (int i = 0; i < s.Length; i++)
            {
                lb.Items.Add(s[i]);
            }

            DataSet ds = wt.getSupportDataSet();
            gv.DataSource = ds.Tables[1];

            //这一个是添加的web服务引用 不知为什么上边的wt不能用
            cn.com.webxml.www.WeatherWebService wws = new cn.com.webxml.www.WeatherWebService();
            s = wws.getWeatherbyCityName("淄博");
            tb.Text=s[10];
            
        }
