[2.0] FTP Uploding and Downloading

I have created a ftp client to FTP server in dotnet using Socket Class or TCPclient class. My process is Download a File from FTP Sever To Local Server and Upload a File From Local server to FTP server. In my Question is what are the Methods to download and upload file.

I want some splitting algorithms of file downloading and uploading. In the normal operation downloading speed is very slow. I want to pause the downloading and uploading process then after some time period then i will continue.
please help me.

I think that you'll find that if you want such fine-grained control you'll have to use the FtpWebRequest and FtpWebResponse classes.
