初试牛刀：实时天气WebService

1.引入WebService：http://www.webxml.com.cn/WebServices/WeatherWebService.asmx

2.声明接口→界面获取值传入接口→接口返回值处理→输入

public string sWeatherHTML = "";

        protected void Button1_Click(object sender, EventArgs e)

        {

            string txtCity=TextBox1.Text;

            cn.com.webxml.www.WeatherWebService ws = new cn.com.webxml.www.WeatherWebService();

            string[] aWeather = ws.getWeatherbyCityName(txtCity);

            StringBuilder sb=new StringBuilder();

            sb.Append("<table>");

            sb.Append(string.Format("<tr><td>城市：</td><td>{0}</td></tr>",aWeather[].ToString()));

            sb.Append(string.Format("<tr><td>温度：</td><td>{0}</td></tr>", aWeather[].ToString()));

            sb.Append(string.Format("<tr><td>气候：</td><td>{0}</td></tr>", aWeather[].ToString()));

            if(aWeather[].ToString()==aWeather[].ToString())

            {

                //转义：前面加@，双  双引号

                sb.Append(string.Format(@"<tr><td>气候：</td><td><img src=""weather/a_{0}""></td></tr>", aWeather[].ToString()));

            }

            else

            {

                sb.Append(string.Format(@"<tr><td>气候：</td><td><img src=""weather/a_{0}"">转<img src=""weather/a_{1}""></td></tr>", aWeather[].ToString(), aWeather[].ToString()));

            }

            sb.Append(string.Format("<tr><td>详情：</td><td>{0}</td></tr>", aWeather[].ToString()));

            sb.Append("</table>");

            sWeatherHTML = sb.ToString();

        }

3.界面显示处理

<body>

    <form id="form1" runat="server">

    <div>

        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

    </div>

    <div>

        <%=sWeatherHTML %>

    </div>

    </form>

</body>
