我想循环一个FTP文件夹,以检查文件是否已到达
我做：
- FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://localhost:8080");
- request.Credentials = new NetworkCredential("anonymous","");
- request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
- while(true)
- {
- using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
- using (Stream responseStream = response.GetResponseStream())
- using (StreamReader reader = new StreamReader(responseStream))
- {
- Console.WriteLine(reader.ReadToEnd());
- reader.Close();
- response.Close();
- }
- }
但在第二次迭代中,我得到一个例外：
The stream cannot be read
解决方法
对不起,我错过了,您只发出一个请求,并尝试多次获得响应.请尝试以下代码：
- while(true)
- {
- FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://localhost:8080");
- request.Credentials = new NetworkCredential("anonymous","");
- request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
- using (FtpWebResponse response = (FtpWebResponse)request.GetResponse())
- using (Stream responseStream = response.GetResponseStream())
- using (StreamReader reader = new StreamReader(responseStream))
- {
- Console.WriteLine(reader.ReadToEnd());
- reader.Close();
- response.Close();
- }
- }
您应该在每个循环结束时添加某种暂停.你不想轰炸服务器.
