推荐答案

您需要找到一些提供 ZIP代码查找的服务.从您的个人资料中可以看到，您在美国，对吗?因此，可能是这样的:
http://www.zip-codes.com/search.asp [ Web服务 的形式提供服务会更方便.这是一个:
http://www.webservicex.net/uszip.asmx [ http://msdn.microsoft.com/en-us/library/ms996486.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/library/6h0yh8f9％28v = vs.80％29.aspx [ ^ ]，
http://msdn.microsoft.com/en-us/库/vstudio/7h3ystb6%28v=vs.100%29.aspx [ http://johnwsaunders3.wordpress.com/2009/05/17 /how-to-consume-a-web-service/ [ Web抓取:
http://en.wikipedia.org/wiki/Web_scraping [从网页中获取特定数据 [如何从另一个站点获取数据 [ ^ ].

我希望您不需要它，因为使用Web服务会更好.

祝你好运，

You need to find some service which provides the ZIP code lookup. As I can see from your profile, you are in U.S., right? So, it could be like this one:
http://www.zip-codes.com/search.asp[^].

It would be more convenient to get a service with is provided as a Web service. Here is one:
http://www.webservicex.net/uszip.asmx[^].

This site provides dual service: you can do the ZIP code lookup through a Web browser as a human operator, or create a Web service client using provided WSDL, which the most convenient way to use the service in your code. I think, you will be able to find other services of this kind. You can do your search and refer to the documentation of the service provider on the services'' sites.

If you are given WSDL, as in this case, the solution is quite easy. Please see:
http://msdn.microsoft.com/en-us/library/ms996486.aspx[^],
http://msdn.microsoft.com/en-us/library/6h0yh8f9%28v=vs.80%29.aspx[^],
http://msdn.microsoft.com/en-us/library/vstudio/7h3ystb6%28v=vs.100%29.aspx[^].

This is some walkthrough article showing how to consume such Web service, with examples:
http://johnwsaunders3.wordpress.com/2009/05/17/how-to-consume-a-web-service/[^].

If, by some reason, you need to use a "regular" Web site oriented for the use of a human operator using the browser, for a lookup of just about anything, you would need to use the techniques of Web scraping:
http://en.wikipedia.org/wiki/Web_scraping[^].

Please see my past answers:
get specific data from web page[^],
How to get the data from another site[^].

I hope you would not need it, because consuming a Web service is way better.

Good luck,
