以下代码是Ajax对基于REST的Web服务的访问的处理代码，但我没学过java，有些类不知道如何与.net中的类相对应，请哪位学过Java的帮忙翻译成C#的。
import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.servlet.*;
import javax.servlet.http.*;
public class YahooSearchGatewayServlet extends HttpServlet {
private static final String YAHOO_SEARCH_URL =
"http://api.search.yahoo.com/WebSearchService/V1/webSearch?appid=thunderboltsoftware"
+ "&type=all";

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

String url = YAHOO_SEARCH_URL + "&" + request.getQueryString();

HttpURLConnection con = (HttpURLConnection)new URL(url).openConnection();
con.setDoInput(true);
con.setDoOutput(true);

con.setRequestMethod("GET");

//Send back the response to the browser
response.setStatus(con.getResponseCode());
response.setContentType("text/xml");

BufferedReader reader = new BufferedReader(new InputStreamReader(con.getInputStream()));
String input = null;
OutputStream responseOutput = response.getOutputStream();

while((input = reader.readLine()) != null) {
responseOutput.write(input.getBytes());
}

}

protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
}
如果您还需要HTML的代码，如下便是：
