Just guessing here but setValue requires a string. You are passing the raw string value. Imagine text contains Hello World. You're script is actually:

   editor.setValue(Hello World);

You need to enclose the string in quotes.

   await Editor.ExecuteScriptAsync($"editor.setValue('{text}');");

It still doesn't change the editor, I am not experienced with this subject.

I think it wants Quotation marks around the text

I need a way to add and remove these Quotation marks

The code I posted puts quotation marks around the value. The result of the earlier example would be:

editor.setValue('Hello World');

Please provide us with any errors you're getting and/or the behavior you're seeing.

I should also point out that I'm assuming that editor is actually the WebView control and not the editor itself. To set the editor you have to do so via the WebView control. Refer to the information here.

Alright cool, I figured out my error, but now I can upload files that are only 1 line long. There are no errors to show.

Yeah, Only 1 line long files work, its odd. I am trying to find a solution

I don't understand. Are you saying that if text is multiple lines then it doesn't execute properly? That's probably because your text has the wrong line endings for JS. You'd need to convert them.

Otherwise please provide a more descriptive comment about the issue you're having and ideally examples.

If the file I am uploading to the editor is over 1 line, it doesn't show in the editor, I don't know how to explain this any better.

Provide the example file. Check the line ending. Try printing the JS code your outputing to the console debugger in the browser.

Its not wanting to upload, but the file is a txt file containing Print("Hello") on line 1 and Print("World") on line 2. It works when I delete line 2 but it fails when line 2 exists. The language is lua.

ReadAllText reads the entire file contents into memory and leaves the CRLF in. If you then try to pass that as a JS string then it isn't going to work, as I already mentioned. To confirm this try reading the file like this:

var text = String.Join("|", File.ReadAllLines(openFileDialog1.FileName));

Your output show have each line separated by a vertical bar. That proves the file contents are read properly. Now switch the vertical bar to "\n" and see what happens.

It works with the bar, but replacing the bar to "\n" doesn't change anything

Try this:

var text = String.Join(@"\n", File.ReadAllLines(openFileDialog1.FileName));

If that doesn't work then I see one person recommending @"\r\n" which is also supported by the editor. Note the verbose syntax so C# doesn't translate it.

It works kinda,
It fails to upload text like this

local OSTime = os.time() local Time = os.date('!*t', OSTime)

That's because of the single quotes inside the string that JS interprets as the end of the string. Unfortunately this is a problem in every language when you're trying to do this kind of thing. You'll need to parse your file input and convert any characters that may cause problems (like single quotes) into something else based upon what you're trying to do. In this very specific case you can probably switch them to double quotes since JS allows both. You can google for solutions to this common string parsing problem if you need to.
