Please give example to get file (auto) from FTP server to local machine with the help of extended stored procedures in in c# application
If I got your point you may not inteding the SQL Stored procedures. you can from C# do the following
//Get List of Files on the FTP
public string[] GetFileList(string URL)
{
string[] downloadFiles;
StringBuilder result = new StringBuilder();
FtpWebRequest reqFTP;
string ftpUserID = "xyz";
string ftpPassword = "123";
try
{
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(URL));
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
reqFTP.Method = WebRequestMethods.Ftp.ListDirectory;
reqFTP.Proxy = null;
WebResponse response = reqFTP.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream());
//MessageBox.Show(reader.ReadToEnd());
string line = reader.ReadLine();
while (line != null)
{
ProcessGotFile(line);
result.Append(line);
result.Append("\n");
line = reader.ReadLine();
}
result.Remove(result.ToString().LastIndexOf('\n'), 1);
reader.Close();
response.Close();
//MessageBox.Show(response.StatusDescription);
return result.ToString().Split('\n');
}
public void ProcessGotFile(string line)
{
string message_id;
FTPclient ftp = new FTPclient();
// download the file
Download(@"D:\", line, "ftp://xyz:123@ftp.theFTP.com");
// Here you got `the` file locally and can start deal with it through the FileInfo class
}
public void Download(string filePath, string fileName, string URL)
{
FtpWebRequest reqFTP;
try
{
string ftpUserID = "xyz";
string ftpPassword = "123";
//filePath = <<The full path where the file is to be created.>>,
//fileName = <<Name of the file to be created(Need not be the name of the file on FTP server).>>
FileStream outputStream = new FileStream(filePath
+ "\\" + fileName, FileMode.Create);
reqFTP = (FtpWebRequest)FtpWebRequest.Create(new Uri(URL + fileName));
reqFTP.Method = WebRequestMethods.Ftp.DownloadFile;
reqFTP.UseBinary = true;
reqFTP.Credentials = new NetworkCredential(ftpUserID, ftpPassword);
reqFTP.Timeout = 500000;
FtpWebResponse response = (FtpWebResponse)reqFTP.GetResponse();
Stream ftpStream = response.GetResponseStream();
long cl = response.ContentLength;
int bufferSize = 2048;
int readCount;
byte[] buffer = new byte[bufferSize];
readCount = ftpStream.Read(buffer, 0, bufferSize);
while (readCount > 0)
{
outputStream.Write(buffer, 0, readCount);
readCount = ftpStream.Read(buffer, 0, bufferSize);
}
ftpStream.Close();
outputStream.Close();
response.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
I hope this help you.
