首先添加WebService 服务引用： http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

namespace WebServiceDemo { public partial class Form1 : Form { public Form1() { InitializeComponent(); } //实例化服务类 WeatherWebServiceSoapClient weather = new WeatherWebServiceSoapClient(); private void Form1_Load(object sender,EventArgs e) { //获取省份 cbProvince.DataSource = weather.getSupportProvince(); } private void cbProvince_SelectedIndexChanged(object sender,EventArgs e) { //获取城市 cbCity.DataSource = weather.getSupportCity(cbProvince.Text.Trim()); } private void cbCity_SelectedIndexChanged(object sender,EventArgs e) { string cityName = cbCity.Text.Trim(); string cName = cityName.Split(new char[] { '(' })[0]; //显示天气信息 lboxMessage.DataSource = weather.getWeatherbyCityName(cName); } } }
