c# - MVC Razor, Include JS / CSS files from another project

Question

I've got a C# MVC project that uses Razor syntax.
To be able to reuse some code, I want to put some of my JavaScript and CSS files in a different project and include them somehow.
This is how my scripts are included at the moment:

<script src="@Url.Content("~/Scripts/bootstrap-typeahead.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/bootstrap-dropdown.js")" type="text/javascript"></script>

At the moment, the scripts are in the same project as the cshtml file but they should be placed in the Common.Web project instead...
What I want to do is this (doesn't work though):

<script src="@Url.Content("Common.Web/Scripts/bootstrap-typeahead.js")" type="text/javascript"></script>
<script src="@Url.Content("Common.Web/Scripts/bootstrap-dropdown.js")" type="text/javascript"></script>

Answer 1

I do this very thing. However I embed the Javascript files and other content in another DLL and then call them from my razor syntax like so. Here is the code I use. In the View: Script example:

        <script src=@Url.Action("GetEmbeddedResource", "Shared", new { resourceName = "Namespace.Scripts.jquery.qtip.min.js", pluginAssemblyName = @Url.Content("~/bin/Namespace.dll") }) type="text/javascript" ></script>

Image Example:

@Html.EmbeddedImage("corporate.gif", new { width = 150, height = 50})

Here is my helper methods:

        public static MvcHtmlString EmbeddedImage(this HtmlHelper htmlHelper, string imageName, dynamic htmlAttributes)
    {
        UrlHelper url = new UrlHelper(HttpContext.Current.Request.RequestContext);
        var anchor = new TagBuilder("img");
        anchor.Attributes["src"] = url.Action("GetEmbeddedResource", "Shared",
                                              new
                                                  {
                                                      resourceName = "Namespace.Content.Images." + imageName,
                                                      pluginAssemblyName = url.Content("~/bin/Namespace.dll")
                                                  });

        if (htmlAttributes != null)
        {
            string width = "";
            string height = "";
            PropertyInfo pi = htmlAttributes.GetType().GetProperty("width");
            if (pi != null)
                width = pi.GetValue(htmlAttributes, null).ToString();

            pi = htmlAttributes.GetType().GetProperty("height");
            if (pi != null)
                height = pi.GetValue(htmlAttributes, null).ToString();

            if (!string.IsNullOrEmpty(height))
                anchor.Attributes["height"] = height;

            if (!string.IsNullOrEmpty(width))
                anchor.Attributes["width"] = width;
        }
        return MvcHtmlString.Create(anchor.ToString());
    }

Lastly my shared Controller:

        [HttpGet]
    public FileStreamResult GetEmbeddedResource(string pluginAssemblyName, string resourceName)
    {
        try
        {
            string physicalPath = Server.MapPath(pluginAssemblyName);
            Stream stream = ResourceHelper.GetEmbeddedResource(physicalPath, resourceName);
            return new FileStreamResult(stream, GetMediaType(resourceName));
            //return new FileStreamResult(stream, GetMediaType(tempResourceName));
        }
        catch (Exception)
        {
            return new FileStreamResult(new MemoryStream(), GetMediaType(resourceName));
        }
    }

    private string GetMediaType(string fileId)
    {
        if (fileId.EndsWith(".js"))
        {
            return "text/javascript";
        }
        else if (fileId.EndsWith(".css"))
        {
            return "text/css";
        }
        else if (fileId.EndsWith(".jpg"))
        {
            return "image/jpeg";
        }
        else if (fileId.EndsWith(".gif"))
        {
            return "image/gif";
        }
        else if (fileId.EndsWith(".png"))
        {
            return "image/png";
        }
        return "text";
    }

Resource Helper:

    public static class ResourceHelper
{
    public static Stream GetEmbeddedResource(string physicalPath, string resourceName)
    {
        try
        {
            Assembly assembly = PluginHelper.LoadPluginByPathName<Assembly>(physicalPath);

            if (assembly != null)
            {
                string tempResourceName = assembly.GetManifestResourceNames().ToList().FirstOrDefault(f => f.EndsWith(resourceName));
                if (tempResourceName == null)
                    return null;
                return assembly.GetManifestResourceStream(tempResourceName);
            }
        }
        catch (Exception)
        {

        }

        return null;
    }
}  

Plugin Helper

public static T LoadPluginByPathName<T>(string pathName)
{
    string viewType = typeof(T).GUID.ToString();

    if (HttpRuntime.Cache[viewType] != null)
        return HttpRuntime.Cache[viewType] is T ? (T)HttpRuntime.Cache[viewType] : default(T);

    object plugin = Assembly.LoadFrom(pathName);
    if (plugin != null)
    {
        //Cache this object as we want to only load this assembly into memory once.
        HttpRuntime.Cache.Insert(viewType, plugin);
        return (T)plugin;
    }

    return default(T);
}

Remember that I am using these as embedded content!
