Is there a way to simulate drag-drop of a file to a website that uses FileReader interface(filereader.js) to upload file, using C#?

I want to programmatically upload file from my C# wpf app to a website that uses the FileReader interface to upload files. When you use the interface there isnt a link that you use to upload file, if there was a link behind upload i could easily upload there.

What I have tried:

I searched a lot online and havent found a way to simulate drag drop to a site that doesnt use a link.

You can only drop a file onto a website that will accept it.

It does accept it. I just dont know how to drop programmatically using C#.

Nor me, but I would guess you need to simulate some actions that would normally be performed by the mouse. Try looking at the source of the website.

I did. But since JS is a new language for me, i havent gotten anywhere yet.

It would make sense to learn the language before you try to use it.

It is not my site so i cannot change it to accept upload in a certain way. I need a way to programmatically upload a file to the site from my WPF windows app and grab output and format and display it in the app window.

Reading between the lines you want to upload files from the user system without their intervention, and if so that's not possible.

No. In the app the user will browse a file from the system and click upload and in the background the app has to upload that file to the site, grab output and format and display it in the app window.
