Question

User-1148373670 posted

HI All,

My Scenario is to download the files from Server using FTP with below conditions.

1. Download the file based on hour basis(Each hour same new file is coming on the server and I want to read only those files not all files). Means  Read the files based on Modified time for yesterday as well today date not based on file names.

Please somebody provide some code snip for this scenario to solve my issue.

Thanks In Advance

You need to use the FtpWebRequest class.

Hi

I am using below code 

FtpWebRequest  webRequest = (FtpWebRequest)FtpWebRequest.Create(downloadFileName);
webRequest.Method = WebRequestMethods.Ftp.DownloadFile;
webRequest.Credentials = new NetworkCredential(userName.Trim(), password.Trim());
webRequest.UsePassive = true;
webRequest.UseBinary = true;
webRequest.KeepAlive = false;

FtpWebResponse  webResponse = (FtpWebResponse)webRequest.GetResponse();

But I am getting exception "The requested FTP command is not supported when using HTTP proxy"

Please help me.

Thanks in advance

A fairly common solution to that error is to set the Proxy property of your FtpWebRequest to null before you call GetResponse.

...
webRequest.KeepAlive = false;
webRequest.Proxy = null;
FtpWebResponse  webResponse = (FtpWebResponse)webRequest.GetResponse();

Give that a try and see if your error clears.
