我用google的首页进行测试的

namespace ConsoleApplication1
{
    class Program
    {
        string apikey = "111111111111111111111111111111";
        string isbnUrl = "http://api.douban.com/book/subject/isbn/";

        static void Main(string[] args)
        {
             //requestUrl = isbnUrl + isbnNo + "?apikey=" + apikey;    
            //eg:http://api.douban.com/book/subject/isbn/9787111298854?apikey=111111111111111111114    
            Program isbnTest = new Program();    
            string isbnNo = "9787111298854";
            string xml = isbnTest.fetchBookInfoByXML(isbnNo);    
            Console.WriteLine(xml);    
        }

        public string fetchBookInfoByXML(string isbnNo)
        {    
            //string requestUrl = isbnUrl + isbnNo + "?apikey=" + apikey;    
            string requestUrl = "http://www.google.com";
            
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUrl);
            request.Method = "GET";
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();

            if (response.StatusCode.ToString() != "OK")
            {
                Console.WriteLine(response.StatusDescription.ToString());
                return "";
            }  

            StreamReader myreader = new StreamReader(response.GetResponseStream(), Encoding.UTF8);  
            string responseText = myreader.ReadToEnd();     
            return responseText;  
              
        }   
    }
}

你这段代码变化不大啊，下面的有些对象，C#里都不是这些，JAVA里才有的啊，所以还是不能用，不过还是谢谢你出力了。

标记下，很有用啊。
