How to check if stylesheet exists
From within my razor template, Is there anyway I can check if the following stylesheet exists before it is called?
```
Url.Content("~/css/my-styles.css")
```
There may be times when I am pulling a template over into a new instance and the stylsheet is not carried over yet, or the stylesheet may be renamed.

Thanks for any tips

No, that doesn't help. I would like to check if the stylesheet exist from the server side.

Does UmbracoContext.Application.Services.FileService help?

Thanks Alex. I have not used this process yet. Would you happen to know of a guide that can walk me through the use of it?

Thanks

In the razor code, you can use server.mappath to get to the directory/file, and then use system.io.file.exists on the returned path.

Nice!

I got it working like this...

@{

    if (System.IO.File.Exists(HttpContext.Current.Server.MapPath("~/css/myTheme.min.css")))
    {
        <link rel="stylesheet" href="@Url.Content("~/css/myTheme.min.css")" />
    }

}

Thanks a lot!
