웹 서버에서 zip 파일을 다운로드하는 WCF에 웹 서비스가 있습니다. 나는 FtpWebRequest을 사용하여 해당 파일을 다운로드하고 있습니다. 내 네트워크가 다운되면 여기 내 코드파일 다운로드 시간이 오래 걸린다
public byte[] DownloadFile(string fileName)
{
int bytesRead = 0;
String downloadUrl = String.Format("{0}{1}/{2}", "ftp://xx.xx.xxx.xxx/datatransfer/", "folder", fileName);
FtpWebRequest req = (FtpWebRequest)FtpWebRequest.Create(downloadUrl);
req.Method = WebRequestMethods.Ftp.DownloadFile;
req.Credentials = new NetworkCredential("uname", "pass");
Stream reader = req.GetResponse().GetResponseStream();
//FileStream fileStream = new FileStream(localDestinationFilePath, FileMode.Create);
byte[] buffer = new byte[2048];
while (true)
{
bytesRead = reader.Read(buffer, 0, buffer.Length);
if (bytesRead == 0)
break;
//fileStream.Write(buffer, 0, bytesRead);
}
return buffer;
}
다운로드 너무 시간이 오래 걸립니다, 그리고 그것은 내 의 Web.config를 다음 오류
The remote server returned an error: NotFound. An exception of type 'System.ServiceModel.CommunicationException' occurred in System.ServiceModel.ni.dll but was not handled in user code

네트워크가 다운 때 큰 파일 을 다운로드 할 수있는 방법이 있나요 lientConfig. web.config에 변경 사항이 있습니까?
네트워크 중단 인터넷 속도 (다운로드 속도)가 느립니다. –
그런 다음 오류 메시지에 설명 된대로 예외를 처리해야합니다. 네트워크 속도가 느린 경우 제한 시간이 초과되었을 수 있습니다. 네트워크가 비정상적으로 느린 경우에는 서비스 및 FTP가 기반으로하는 서비스 중단 및 TCP가 끊임없이 필요합니다. – nvoigt
