修改ASP.NET MVC中的样式表属性

Question

I am preloading stylesheets inside this method OnResultExecuting(ResultExecutingContext filterContext) in MVC, this is just to make sure that this is done before the actionResult is called when loading the page, and this works fine, my issue is now i want to modify the style sheet background-image property in a class called logo and before the tag is built(code below) and added to the head section in the DOM, I'm wondering if there isn't a way to read(StreamReader?/StreamWriter?) the css file and modify it and save it before the tag is built or something like that, btw Im getting the css file from the server.

foreach (string file in filepath)
{
    if (Path.GetExtension(file).ToLower() == ".css")
    {
        TagBuilder link = new TagBuilder("link");
        link.Attributes["rel"] = "stylesheet";
        link.Attributes["type"] = "text/css";
        link.Attributes["href"] = urlHelper.Content(
            string.Format("~/Content/themes/Theme{0}/{1}",
                setting.ThemeId, Path.GetFileName(file)));

        resources.Add(MvcHtmlString.Create(link.ToString(TagRenderMode.SelfClosing)));
    }
}

您可以在此样式表之后加载另一个样式表，然后以这种方式修改类样式，实际上这正是我为白色标签解决方案执行的操作。

Can´t you use LESS to dinamicaly create your css?
