| How to upload, download and delete a file |

Uploading, downloading and deletion of files is all done through simple method calls on the FTPConnection
Uploading Files
Uploading of a file is done by the following method-call:
ftpConnection.UploadFile(localFilePath, remoteFileName);
This method uploads the file specified by the first argument and saves it on the server with the name specified by the second argument. If the file is already present on the server then it is usually overwritten, though this depends on the server configuration.
File appending is also supported, whereby the contents of the local file are appended to the end of the remote file. Appending is done by passing a third parameter to the UploadFile() method:
ftpConnection.UploadFile(localFilePath, remoteFileName, true);
Downloading Files
Downloading of a file is done by the following method-call:
ftpConnection.DownloadFile(localFilePath, remoteFileName);
This method downloads the file specified by the second argument and saves it locally with the name specified by the first argument. If the file is already present on the local storage medium then it is overwritten.
A remote file can also be downloaded into memory as a byte array:
ftpConnection.DownloadByteArray(remoteFileName);;
Deleting Files
A file may be deleted by calling the DeleteFile method.
Notes:
(1) It is often useful to use streams to transfer data directly to and from memory. The topic How to transfer using FTP streams explains how to do this.
