如何用c#编辑获取Webservice上的天气信息生成XML文档

Question

题目如上，我是个新手，代码实现上有些困难，总是会出现错误，希望
1，用代码实现获取天气信息，能告诉下思路（希望不是自己创建Webservice和网上的同步）
2，给出部分代码参考，代码格式多点更好！
3，如何在VS2008上生成XML格式，告诉下具体操作.
4，能够加Timer控件，3小时刷新下数据（方便的话就给）
在线等答案，谢谢帮助！

Answer 1

http://www.webxml.com.cn/WebServices/WeatherWebService.asmx
WeatherWebService wws = new WeatherWebService();
string[] weatherArray = wws.getWeatherbyCityName("");
Console.WriteLine("{0}-{1}-{2}", weatherArray[6], weatherArray[7], weatherArray[8]);
Console.Read();
htpwebrequest抓取天气数据
System.Threading.Timer tUpdatefile = new System.Threading.Timer(new TimerCallback(test), null, 0, 3*60*60 * 1000);
 private void test(object source)

有部分没看懂 能QQ和你联系么~我QQ是349954464~

Answer 3

如果说WeatherWebService 缺少程序集引用，该怎么办？

Answer 4

我来补充一下，怎么使用这个WebService
1. 添加Web引用：把这个WSDL拷贝到地址栏中：
"http://www.webxml.com.cn/WebServices/WeatherWebService.asmx"2. 然后重新命名一下这个WebService名，默认是Service1(这个是生成代码的namespace)
   应该会生成一个app.config文件，   <bindings>配置节里有个customerBindings的配置节可以删去。   <endpoint>也有重复的，把那个WeatherWebServiceSoap12的节点删去。3. 看下面的代码就可以用了。
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 System.Text.RegularExpressions;namespace CallWebServices
{
    public partial class Form1 : Form
    {
        private WeatherWebServices.WeatherWebServiceSoapClient weatherWebSvc = null;        public Form1()
        {
            InitializeComponent();
        }        private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                weatherWebSvc = new CallWebServices.WeatherWebServices.WeatherWebServiceSoapClient();
                weatherWebSvc.Open();                string[] cities = weatherWebSvc.getSupportCity("");                DataTable weatherData = new DataTable();
                weatherData.Columns.Add("province");
                weatherData.Columns.Add("city");
                weatherData.Columns.Add("city_code");
                weatherData.Columns.Add("city_image");
                weatherData.Columns.Add("last_update_time");
                weatherData.Columns.Add("temperature");
                weatherData.Columns.Add("summary");
                weatherData.Columns.Add("wind_direction");
                weatherData.Columns.Add("wind_power");
                weatherData.TableName = "WeatherData";                Regex regex = new Regex(@"(\d+)");                foreach (string city in cities)
                {
                    string cityCode = regex.Match(city).Value;
                    string[] weatherDataArr = weatherWebSvc.getWeatherbyCityName(cityCode);
                    DataRow row = weatherData.NewRow();
                    for (int i = 0; i < weatherData.Columns.Count; i++)
                        row[i] = weatherDataArr[i];
                    weatherData.Rows.Add(row);
 
                    //城市太多了，全查受不了，所以随便查几个就Stop了。
                    if (weatherData.Rows.Count > 5)
                        break;
                }                //绑定查询结果，显示
                this.dataGridView1.DataSource = weatherData;
                //利用DataTable保存成Xml
                weatherData.WriteXml(@"D:\temp\weather.xml");                weatherWebSvc.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
            finally
            {
                try
                {
                    weatherWebSvc.Close();
                }
                catch
                { }
            }
            
        }
    }
}

Answer 5

先谢谢，有些地方还没看懂，先给分了，写的太好 我学的太浅薄了 有点看不懂。
System.Threading.Timer tUpdatefile = new System.Threading.Timer(new TimerCallback(test), null, 0, 3*60*60 * 1000);  能帮我拆分解释下么。
