convert a resource into a byte array without writing to disk

My question is:

Is there a way to convert a resource directly to byte array without writing to disk?

The code is:

using System;
using System.IO;
using System.Reflection;

namespace VCSKicks
{
    public static class ResourceHelper
    {
        public static string GetEmbeddedResource(string resourceName)
        {
            return GetEmbeddedResource(resourceName, Assembly.GetCallingAssembly());
        }

        public static byte[] GetEmbeddedResourceAsBytes(string resourceName)
        {
            return GetEmbeddedResourceAsBytes(resourceName, Assembly.GetCallingAssembly());
        }

        public static string GetEmbeddedResource(string resourceName, Assembly assembly)
        {
            resourceName = FormatResourceName(assembly, resourceName);
            using (Stream resourceStream = assembly.GetManifestResourceStream(resourceName))
            {
                if (resourceStream == null)
                    return null;

                using (StreamReader reader = new StreamReader(resourceStream))
                {
                    return reader.ReadToEnd();
                }
            }
        }

        public static byte[] GetEmbeddedResourceAsBytes(string resourceName, Assembly assembly)
        {
            using (Stream resourceStream = assembly.GetManifestResourceStream(resourceName))
            {
                byte[] content = new byte[resourceStream.Length];
                resourceStream.Read(content, 0, content.Length);

                return content;
            }
        }

        private static string FormatResourceName(Assembly assembly, string resourceName)
        {
            return assembly.GetName().Name + "." + resourceName.Replace(" ", "_").Replace("\", ".").Replace("/", ".");
        }
    }
}
