Hi,
I've written a windows application to upload the files to our ftp location using .NET v1.1. Now my requirement is to find out the time that will take to upload the selected files.
Inother words, how can i show the estimated time to transfer any file on the internet
Any suggestion are highly helpful to me..
Thanks and Regards,
Chakravarthy
How to trace time for FTP Upload
Spatulas
Hi,
Great logic. But can you tell me about how can i get the uploaded size of the current file
Inother words, if i'm uploading a file to FTP Server, how do i get to know, howmuch data is being transferred to the FTP Site at any given time
Regards

Hi!
Simple way: time left = used time * downloaded size / total size
Smooth way: keep last 3 (or 10) expected time values and display average of them (this will hide minor fluctuations).

You must update estimated time after this line.

Here is the code to upload a file.
Source: http://www.csharphelp.com/archives/archive9.html
public void Upload(string fileName, bool resume)
{
if ( !this.loggedin ) this.Login();
Socket cSocket = null ;
long offset = 0;
if ( resume )
{
try
{
this.BinaryMode = true;
offset = GetFileSize( Path.GetFileName(fileName) );
}
catch(Exception)
{
// file not exist
offset = 0;
}
}
// open stream to read file
FileStream input = new FileStream(fileName,FileMode.Open);
if ( resume && input.Length < offset )
{
// different file size
Debug.WriteLine("Overwriting " + fileName, "FtpClient");
offset = 0;
}
else if ( resume && input.Length == offset )
{
// file done
input.Close();
Debug.WriteLine("Skipping completed " + fileName + " - turn resume off to not detect.", "FtpClient");
return;
}
// dont create untill we know that we need it
cSocket = this.createDataSocket();
if ( offset > 0 )
{
this.sendCommand( "REST " + offset );
if ( this.resultCode != 350 )
{
Debug.WriteLine("Resuming not supported", "FtpClient");
offset = 0;
}
}
this.sendCommand( "STOR " + Path.GetFileName(fileName) );
if ( this.resultCode != 125 && this.resultCode != 150 ) throw new FtpException(result.Substring(4));
if ( offset != 0 )
{
Debug.WriteLine("Resuming at offset " + offset, "FtpClient" );
input.Seek(offset,SeekOrigin.Begin);
}
Debug.WriteLine( "Uploading file " + fileName + " to " + remotePath, "FtpClient" );
while ((bytes = input.Read(buffer,0,buffer.Length)) > 0)
{
cSocket.Send(buffer, bytes, 0);
}
input.Close();
if (cSocket.Connected)
{
cSocket.Close();
}
this.readResponse();
if( this.resultCode != 226 && this.resultCode != 250 ) throw new FtpException(this.result.Substring(4));
}
