一：截图

二：实现步骤

1、引入Web服务。在VS中项目上右击→添加服务引用。

2、在弹出的添加服务引用窗口，录入web服务地址和引用后的命名空间。

三：源代码

namespace weather
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btn_search_Click(object sender, EventArgs e)
        {
           //System.Net.ServicePointManager.Expect100Continue = false;
           weather.weatherxml.WeatherWebService w = new weather.weatherxml.WeatherWebService();
            string[] s = new string[];
            string city = this.tb_city.Text.Trim();
            s = w.getWeatherbyCityName(city);
            if (s[]=="")
            {
                MessageBox.Show("暂时不支持您查询的城市");
            }
            else
            {
                this.lbl_view.Text = s[] + " " + s[];
                tb_all.Text = s[];
            }
        }
        }
    }
