How can I filterresources from an external assembly by type (text, icons, etc.)?

[Erik]

Hello, I already figured out how to load another assembly from my C# application, and extract the resources embedded to that assembly. My problem is that I'd like to filter the resources by type, i.e. I want to get only text resources, but not icons and other stuff. The code I use at the moment looks like this:

Assembly target = Assembly.LoadFile(filename);
string[] list = target.GetManifestResourceNames();

            foreach (var listentry in list)
            {
                Stream resourceStream = target.GetManifestResourceStream(listentry);

                var rr = new ResourceReader(resourceStream);
                IDictionaryEnumerator dict = rr.GetEnumerator();
                int ctr = 0;
                while (dict.MoveNext())
                {
                    ctr++;
                    string entry = dict.Value; //I'd like to know what kind of resource this is, how can I do that?

                }
                rr.Close();
            }

How can I determine which kind of resource entry I currently get, i.e. if it's an icon, a text resource, or something else?
