可以考虑创建一个　XMLHTTP　ACTIVEX对象，用它来获取网络上某个文件的内容。

private void GetRadarId(string zip)

{

try{

string url = "http://www.weather.com/weather/local/"+zip;

HttpWebRequest wr = (HttpWebRequest)WebRequest.Create

(url);

HttpWebResponse ws = (HttpWebResponse)wr.GetResponse();

Stream str = ws.GetResponseStream();

StreamReader sr = new StreamReader(str);

string line = " ";

while(line.IndexOf("mapURLPre") == -1){

line = sr.ReadLine();

}

string[] tokens = line.Split(new char[] {'_'});

radarid = tokens[2].Substring(0,3);

}

catch(Exception ex) {}

}

楼上：
radarid = tokens[2].Substring(0,3);

什么意思？

如果是文本文件
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url);
HttpWebResponse ws = (HttpWebResponse)wr.GetResponse();
Stream str = ws.GetResponseStream();
StreamReader sr = new StreamReader(str,System.Text.Encoding.Default);
string b=sr.ReadToEnd();
