Using @ import to import files from a different folder

I have a base file (_Base.scss), all others files used this file.

With the following structure:

/Content
     _Base.scss
     /page
         /home
             index.scss

I would like to import the file _Base.scss into my index.scss

I tried something like:

@import "~/Content/_Base.scss";

or

@import url("~/Content/_Base.scss");

or

@import url("/Content/_Base.scss");

or

@import "/_Base.scss";

But none of these work!

Error

/* An error occurred while compiling the Sass file. Message:

Error on line 1 Sass::SyntaxError File to import not found or unreadable: /_Base.scss. Load path: C:/Users/Riderman/Work/Clients/BindSoluction/bindsolution.website/BindSolution/Content/pages/home

The Sass compiler is an external component and doesn't recognise the ASP.NET "~/" convention. Using a relative path worked for me:

@import "../test.scss";
