To copy files from one location to shared location using C#

Hello use this code-

 

string ftpUserName = ConfigurationSettings.AppSettings["ftpuserid"].ToString();

string ftpPassword = ConfigurationSettings.AppSettings["ftppasswrd"].ToString();

string ftppath = ConfigurationSettings.AppSettings["ftppath"].ToString();

string localpath = ConfigurationSettings.AppSettings["localpath"].ToString();

try

{

if (!System.IO.Directory.Exists(localpath))

{

Console.ForegroundColor = ConsoleColor.Red;

Console.WriteLine("ERROR in Step 2.1 : Directory does not exist.");

cLog.ErrorLog(path1, "ERROR in Step 2.1 : Directory does not exist.");

Console.ResetColor();

}

else

{

DirectoryInfo DirInfo = new DirectoryInfo(localpath);

var files = from file in DirInfo.EnumerateFiles()

where file.CreationTimeUtc > dtLastModified

//where file.LastWriteTimeUtc > dtLastModified // .CreationTimeUtc > dt1 &

orderby file.LastWriteTimeUtc ascending

//file.CreationTimeUtc < dtLastModified

select file;

//string[] files = System.IO.Directory.GetFiles(localpath);

foreach (var fi in files)

{

DateTime lastModifie = fi.LastWriteTimeUtc;

DateTime creationTime = fi.CreationTimeUtc;

DateTime lastAccessTime = fi.LastWriteTimeUtc;

//if (lastModifie <= dtLastModified)

//{

// //==== leave this file

//}

//else

//{

//================== FTP upload =======================//

// come here.....

FtpWebRequest req = (FtpWebRequest)WebRequest.Create((ftppath) + fi.Name);

req.Credentials = new NetworkCredential(ftpUserName, ftpPassword);

string localPath = localpath + fi.Name;

req.Timeout = 90000;

try

{

UploadFile(req, localPath, -1);

Console.ForegroundColor = ConsoleColor.Green;

Console.WriteLine("File uploaded : " + fi.Name);

Console.ResetColor();

}

catch (Exception ex)

{

Console.ForegroundColor = ConsoleColor.Red;

Console.WriteLine("ERROR in Step 2.2 : File Not Uploaded.");

Console.ResetColor();

// We have to close down application.. if error occurs.

}

finally

{

req = null;

}

//=====================================================//

//}

}

}

}

const Int32 defaultBufferSize = 1024; // 1KB

public static void UploadFile(FtpWebRequest req, string localFilePath, Int32 bufferSize)
