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.
