Uploading a file to web server/host using c#?

If you have made a window form application and you want to upload a file, you can use ftp managers such as: CuteFTP, Filezilla, TurboFTP, SmartFTP, etc. But If you make Asp website or Asp application or any other web application with visual studio then you can publish (upload) your website and files:
1- Right click on your website or web application name in Visual Studio.
2- Left click on “Publish”.
3- Choose publish method.
4- Enter your server address and credentials.
5- Publish your website.

Use WebScrapper it currently ready to upload to 22 File host and it already analyzed it for you. If you don't find the file host you want in the WebScrapper package, you can create your own syntax by analyzing the file host's HTML
