C# core MVC where collections with currently added files as CSS are stored in cshtml?

Question

See more:

I'd like to find where they're stored files (or paths) like javascripts, css, images. By write I mean for example

<link href="@Url.Content("~/css/table.css")" rel="stylesheet" type="text/css" />

If there is a collection in the root cshtml object (this) where another style is added, or how it works?

What I have tried:

I tried to search this object, but it is quite large and maybe these collections are not even there.

Solution 1

Simple: the file is called table.css, and it's in the css folder in the root of your site.

Since you haven't explained what you mean by "collections" and "this object", we can't tell you anything else.

I wrote "this" object in cshtml, I mean if you set break point in cshtml file, when debugging set variable "this" (Watch window) which is an object AspNetCore._Views_Shared_Components_ViewName type. By collection I meant List, Array, or something where you can get a list of files at runtime and then list them in a view, for example. Files can be added from different places, from different directories, projects..., I would like a list of all the files the view has access to.

Richard Deeming 21-Sep-21 4:31am

Still not clear. The view has "access" to any file in your site. That will include all of the files physically included in your project, and any files in any virtual directories configured within IIS.

And technically, it can include CSS/Javascript/image files from external sites as well, so the list is basically "every file on the entire internet".

If I add a new css file or something else, where does this information go? I mean into some object that has a list inside.

Richard Deeming 21-Sep-21 4:37am

If you add a new file, it "goes" wherever you add that file. If you add it in the css folder, then that's where it is.

But this is not adding a file, this is just referencing it for the view. There may be many files in the directory, but only some are referenced in the view. How does the view find out which file has been referenced and which has not? It probably has to have it written down somewhere, which is what I'm looking for.

Richard Deeming 21-Sep-21 4:47am

It is written down - it's right there in the view!

<link href="@Url.Content("~/css/table.css")" rel="stylesheet" type="text/css" />

That generates an HTML <link> element which references the table.css file from the css folder.

The view doesn't magically reference files that you don't tell it to. Only the files you reference in the view, or its layout, will be referenced in the final HTML which is sent back to the browser.

I understand, but is there any way to get lists of all these files on run time?

Richard Deeming 21-Sep-21 5:00am

No. The reference to the URL is rendered when the view is executed. It doesn't maintain a list of referenced URLs.

You'd need to intercept the generated HTML and parse it to find the references. And even then, it wouldn't be completely accurate, since some types of file can bring in references to other files - eg: @import[^] in CSS files, import[^] in Javascript modules, etc.

Ok, thanks for your help and patience.
