  The FTP protocol does not have a "pause" function.  The way you would accomplish this is as follows:
  

  1.  Cancel the upload by canceling the write process (this assumes you are writing data to server in chunks e.g. 1024 byte chunks).
  

  2.  Get size  of remote file partially uploaded.  This can be done using the SIZE [filename] command and will return the partial file upload size.
  

  3.  Send REST [offset] command to, where [offset] is the length of partial file upload.

  4.  Send STOR [filename] command as you would using normal file upload.  

  5.  Send data for [filename] starting with [offset].

  For an API that does this for you, check out the following FTP .NET API.  The method you want to use is Ftp.ResumeUpload
