Hello,

How to resolve operation timed out problem in c# .net windows service?

I am writing this code:-

C#

private void DownloadFile(string file)
       {

 FTPSettings.IP = "abc.com/xyz";
                FTPSettings.UserID = "xxxxx";
                FTPSettings.Password = "xxxxx";
                string uri = "ftp://" + FTPSettings.IP + "/" + "Testing" + "/" + file;
                Uri serverUri = new Uri(uri);
                if (serverUri.Scheme != Uri.UriSchemeFtp)
                {
                    return;
                }
                FtpWebRequest reqFTP;
                reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri("ftp://" + FTPSettings.IP + "/" + "Testing" + "/" + file));                                
                reqFTP.Credentials = new NetworkCredential(FTPSettings.UserID, FTPSettings.Password);                
                reqFTP.KeepAlive = false;                
                reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;                                
                reqFTP.UseBinary = true;
                reqFTP.Proxy = null;                 
                reqFTP.UsePassive = false;
                FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
                Stream responseStream = response.GetResponseStream();
                FileStream writeStream = new FileStream(@"D:\ABC\XYZ\bin\" + file, FileMode.Create);
                
                int Length = 2048;
                Byte[] buffer = new Byte[Length];
                int bytesRead = responseStream.Read(buffer, 0, Length);               
                while (bytesRead > 0)
                {
                    writeStream.Write(buffer, 0, bytesRead);
                    bytesRead = responseStream.Read(buffer, 0, Length);
                }                
                writeStream.Close();
                response.Close();

Why are you using Rebex rather than .Net?

Rebex is a license trial version.
We have to purchase.

The following code was tested and did not encounter a timeout
