C# 天气预报

问题描述：

使用C#做一个简易的天气预报系统

问题解决：

主要使用类如下：

WeatherLoc：包含常用的调用中国气象局天气情况接口

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using WeatherReport.ServiceReference1;

namespace WeatherReport
{
    class WeatherLoc
    {
           //调用天气接口的类

private static WeatherWebServiceSoapClient ws= new WeatherWebServiceSoapClient("WeatherWebServiceSoap"

);

        public WeatherLoc()
        {
        }

     //查看天气接口支持的省份
        public String[] GetSupportProvince()
        {
            String[] supportProv = ws.getSupportProvince();
            return supportProv;
        }

    //查看天气情况支持的城市
        public String[] GetSupportCity(String province)
        {
            return ws.getSupportCity(province);
        }

     //查看指定城市的天气信息
        public WeatherInfo GetWeatherInfo(String city)
        {
            String[] allInfo = ws.getWeatherbyCityName(city);
            WeatherInfo weather = new WeatherInfo();
            weather.Province = allInfo[];
            weather.CityName = allInfo[];
            weather.LastUpdateTime = allInfo[];
            weather.Temperature = allInfo[];
            weather.WeatherLive = allInfo[];
            weather.LivingIndex = allInfo[];
            weather.CityInfo = allInfo[];

            FutureInfo[] future = new FutureInfo[];

            //今天天气信息
            future[].temp = allInfo[];
            future[].overView = allInfo[];
            future[].windDirection = allInfo[];
            future[].tendencyBeg = allInfo[];
            future[].tendencyEnd = allInfo[];

            //明天的天气信息
            future[].temp = allInfo[];
            future[].overView = allInfo[];
            future[].windDirection = allInfo[];
            future[].tendencyBeg = allInfo[];
            future[].tendencyEnd = allInfo[];

            //后天的天气信息
            future[].temp = allInfo[];
            future[].overView = allInfo[];
            future[].windDirection = allInfo[];
            future[].tendencyBeg = allInfo[];
            future[].tendencyEnd = allInfo[];

            weather.FutureInfo = future;

            return weather;
        }
    }
}

WeatherInfo类：包含查询天气情况信息

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace WeatherReport
{
    //未来三天天气情况结构体,C#中结构体默认访问权限是private，C++结构体默认访问权限为public
    struct FutureInfo
    {
       public String temp;    //温度
       public String overView;    //概况
       public String windDirection;   //风向和风力
       public String tendencyBeg; //趋势开始图片
       public String tendencyEnd; //趋势结束图片
    };

    class WeatherInfo
    {
        private String province;    //省份
        private String cityName;    //城市名称
        private String lastUpdateTime;  //最后更新时间
        private String temperature; //温度
        private FutureInfo[] info;  //未来三天天气情况
        private String weatherLive; //现在天气实况
        private String livingIndex; //生活指数
        private String cityInfo;    //城市介绍

        public WeatherInfo()
        {
            cityName = "";
            lastUpdateTime = "";
            temperature = "";
            info = new FutureInfo[];
            weatherLive = "";
            livingIndex = "";
            cityInfo = "";
        }

        public String Province
        {
            get
            {
                return province;
            }
            set
            {
                province = value;
            }
        }

        public FutureInfo[] FutureInfo
        {
            get
            {
                return info;
            }
            set
            {
                info = value;
            }
        }

        public String CityName
        {
            get
            {
                return cityName;
            }

            set
            {
                cityName = value;
            }
        }

        public String LastUpdateTime
        {
            get
            {
                return lastUpdateTime;
            }
            set
            {
                lastUpdateTime = value;
            }
        }

        public String Temperature
        {
            get
            {
                return temperature;
            }
            set
            {
                temperature = value;
            }
        }

        public String WeatherLive
        {
            get
            {
                return weatherLive;
            }
            set
            {
                weatherLive = value;
            }
        }

        public String LivingIndex
        {
            get
            {
                return livingIndex;
            }
            set
            {
                livingIndex = value;
            }
        }

        public String CityInfo
        {
            get
            {
                return cityInfo;
            }
            set
            {
                cityInfo = value;
            }
        }
    }
}

具体使用中国气象局天气接口方法如下：

（1）添加服务引用

（2）包含服务器引用接口

（3）接口使用，参考WeatherLoc类中接口调用

执行效果：
