In my public static void ResumePut(FTPConnection ftp, CalicoWS.FTP objFTPDetails, string zipfileName)
procedure where I have the following code, must have a true for append and then it works:
try
{
if (ftp1.Exists(fname) == true)
{
ftp1.ResumeTransfer();
ftp1.UploadFile(zipfileName, fname,true);
}
else
{
}
ftp1.Close();
}
catch (System.Exception ex1)
{
ftp1.Close();
}
