Simple FTP Uploader Using Zip File For Software Update

This program is designed to upload an XML file and a zip file automatically created to your FTP server. It can be used for software update.

Introduction

If you want to upload some files to your FTP server, you can put these files to the FTP server one by one.

But if the local directory path of these files is different from each other, you should check on the FTP server whether all those directory names exist or not.

Furthermore, if some file's path has many directories, you should create the directories in FTP server step by one. Because you can't create a directory having 2 more steps not existing at once.

It's uncomfortable for me, so, I will make a zip file and put all files on it. ZipArchive offers to create a hierarchy directory by once.

Background

  1. Drag drop files into a datagrid control in WPF project.
  2. When clicking the button which is labeled 'save and upload', the program run creates an XML file (contains files information like path, size, writetime) and makes zip file automatically, and all the files you drag-dropped on it.
  3. Then, that XML and ZIP file will be uploaded to the FTP server you indicated.
  4. For this, you should know the relative directory path.

    For example, if you add two files in a zip file and they are in different directory paths, you should know a base root path to create an entry folder path in a zip.

    First file's real path is d:\abcd\goodjob.txt

    Second file's real path is d:\abcd\folder\goodjob1.txt

    Then, the local root path must be considered 'd:\abcd\'

    So, the first file's relative path is '\goodjob.txt' and the second file's relative path is 'folder\goodjob1.txt'.

  5. In short, zip file's root has one file and one directory entry called folder and 'goodjob1.txt' file will be in that.

Using the Code

First, you do create a WPF project using .NET 4.6.

The reason why I'm using that version is that ZipArchive class is offered after .NET 4.5 as I know.

This code below is for 'MainWindow.xaml'.

First of all, you must drag drop files you want to a DataGrid control named 'dgToUploadFiles'.

Then, input FTP server URL to the 'Server Root Url'.

If you have to manage different kinds of program version files, you can use the 'Key Directory'. The directory will be created automatically in the FTP server next to 'Server Root Url/SWUpdate/'.

Lastly, you should input the id and password, and click the 'Save and Upload' button.

Points of Interest

The reason why I'm creating file information to XML file is because it is easy to read from the web server.

After setting web server by IIS, if your FTP server URL and web server URL located to the same location. You can use the 'WebClient' which is offered by .NET.
