asp.net实现根据城市获取天气预报的方法
本文实例讲述了asp.net实现根据城市获取天气预报的方法。分享给大家供大家参考，具体如下：
publicvoidGetWetheaerByCity(stringcityName){
stringcity=cityName;
stringmycity=HttpUtility.UrlEncode(city,System.Text.Encoding.GetEncoding("GB2312"));
System.Net.HttpWebRequestrequest=(System.Net.HttpWebRequest)System.Net.WebRequest.Create("http://www.sina.com/index.php?city="+cityName);
//HttpWebRequest对象获取GetResponse转换成HttpWebResponse
System.Net.HttpWebResponseresponse=request.GetResponse()asSystem.Net.HttpWebResponse;
//通过HttpWebResponseresponse.GetResponseStream()获取输出流
Streamstr=response.GetResponseStream();
StreamReaderreader=newStreamReader(str,System.Text.Encoding.GetEncoding("GB2312"));
stringweathhtml=reader.ReadToEnd();
str.Close();
reader.Close();
}
希望本文所述对大家asp.net程序设计有所帮助。
