How to include CSS styles inline in Razor view?

Question

I am using Postal to render MVC Razor views and send them via email. I have a custom CSS that I have defined specifically for the email views. Currently I am including them

Upvoted Paul d'Aoust's answer, but I found this version of his helper method to work a little better for me (wouldn't try to encode things like quotes in the CSS):

public static class CssHelper
{
  public static IHtmlString EmbedCss(this HtmlHelper htmlHelper, string path)
  {
    // take a path that starts with "~" and map it to the filesystem.
    var cssFilePath = HttpContext.Current.Server.MapPath(path);
    // load the contents of that file
    try
    {
      var cssText = File.ReadAllText(cssFilePath);
      return htmlHelper.Raw("");
    }
    catch
    {
      // return nothing if we can't read the file for any reason
      return null;
    }
  }
}
