There is no way to enumerate the files set as "Content".

However, there is a way to enumerate files at runtime, if you set your files as "Embedded Resource".

Here is how you can do this:

1. Set the Build Action of your images as "Embedded Resource".
2. Use Assembly.GetCallingAssembly().GetManifestResourceNames() to enumerate the resources names
3. Use Assembly.GetCallingAssembly().GetManifestResourceStream(resName) to get the file streams.

Here is the code:

    public void Test()
    {
        foreach (String resName in GetResourcesNames())
        {
            Stream s = GetStreamFromEmbeddedResource(resName);
        }
    }

    string[] GetResourcesNames()
    {
        return Assembly.GetCallingAssembly().GetManifestResourceNames();
    }

    Stream GetStreamFromEmbeddedResource(string resName)
    {
        return Assembly.GetCallingAssembly().GetManifestResourceStream(resName);
    }

EDIT : As quetzalcoatl noted, the drawback of this solution is that images are embedded in the DLL, so if you a high volume of images, the app load time might take a hit.
