I would like to ask a question about loading static files (for example .png file) and using Virtual Path Provider.
So, I created project with App_Start:
public static void Start()
{
ConfigureBundles();
BundleConfig.RegisterBundles(BundleTable.Bundles);
RouteConfig.RegisterRoutes(RouteTable.Routes);
//etc.
}
private static void ConfigureBundles()
{
BundleTable.EnableOptimizations = true;
BundleTable.VirtualPathProvider = new EmbeddedVirtualPathProvider(HostingEnvironment.VirtualPathProvider);
}
And prepare the overwrite method in another class:
// virtual path
public class EmbeddedVirtualPathProvider : VirtualPathProvider
{
private VirtualPathProvider _previous;
public EmbeddedVirtualPathProvider(VirtualPathProvider previous)
{
_previous = previous;
}
public override bool FileExists(string virtualPath)
{
if (IsEmbeddedPath(virtualPath))
return true;
else
return _previous.FileExists(virtualPath);
}
public override CacheDependency GetCacheDependency(string virtualPath, IEnumerable virtualPathDependencies, DateTime utcStart)
{
if (IsEmbeddedPath(virtualPath))
{
return null;
}
else
{
return _previous.GetCacheDependency(virtualPath, virtualPathDependencies, utcStart);
}
}
public override VirtualDirectory GetDirectory(string virtualDir)
{
return _previous.GetDirectory(virtualDir);
}
public override bool DirectoryExists(string virtualDir)
{
return _previous.DirectoryExists(virtualDir);
}
public override VirtualFile GetFile(string virtualPath)
{
if (IsEmbeddedPath(virtualPath))
{
string fileNameWithExtension = virtualPath.Replace("~/", string.Empty).Replace("/", ".").Replace("\\", ".").TrimStart(new char[] { '.' });
string nameSpace = "myApp";
string manifestResourceName = string.Format("{0}.{1}", nameSpace, fileNameWithExtension);
Stream stream = null;
foreach(var assembly in AppDomain.CurrentDomain.GetAssemblies().Where(a => a.FullName.StartsWith("myApp")).ToList())
{
stream = assembly.GetManifestResourceStream(manifestResourceName);
if (stream != null)
break;
}
return new EmbeddedVirtualFile(virtualPath, stream ?? new MemoryStream());
}
else
return _previous.GetFile(virtualPath);
}
private bool IsEmbeddedPath(string path)
{
return path.Contains("Scripts") || path.Contains("Content") || path.Contains("bundles") || path.Contains("Fonts") || path.Contains("Gfx");
}
}
public class EmbeddedVirtualFile : VirtualFile
{
private Stream _stream;
public EmbeddedVirtualFile(string virtualPath, Stream stream)
: base(virtualPath)
{
_stream = stream;
}
public override Stream Open()
{
return _stream;
}
}
And last step I prepare Global.asax:
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
ConfigureBundles();
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
}
private static void ConfigureBundles()
{
BundleTable.EnableOptimizations = true;
BundleTable.VirtualPathProvider = new EmbeddedVirtualPathProvider(HostingEnvironment.VirtualPathProvider);
}
}
All my css file and js file have set Build Action on Embedded Resource and this works very well in my main project.
What must I do if I want static files to load from external assembly into main project in the same way?
Thanks for help !!
