Question

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using 天气预报.com.ayandy.www;namespace 天气预报
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            com.ayandy.www.Service weather = new 天气预报.com.ayandy.www.Service();
            weather.getSupportCityCompleted += new com.ayandy.www.getSupportCityCompletedEventHandler(A);
            weather.getSupportCityAsync("成都", theDayFlagEnum.Tomorrow);
        }
        public void A(object sender, getSupportCityCompletedEventArgs e)
        {
            this.textBox1.Text = e.Result[0];
        }    }
}添加web引用http://www.ayandy.com
只是简单的天气预报异步调用
public void A(object sender, getSupportCityCompletedEventArgs e)
        {
            this.textBox1.Text = e.Result[0];
        }这部分有些问题，没有思路，希望给点帮助
