A manifest resource is a resource (such as an image file) that is embedded in the assembly at compile time. For more information about manifest resources, see Microsoft .NET Framework Resource Basics in the MSDN Library.

Resource information is returned only if the resource is visible to the caller, or the caller has ReflectionPermission.


This method returns null if a private resource in another assembly is accessed and the caller does not have ReflectionPermission with the ReflectionPermissionFlag.MemberAccess flag.

If the assembly manifest lists a resource file, GetManifestResourceStream returns a Stream object even if the resource file cannot be found on disk at the time. If the resource file is not found, passing the resulting Stream object to the ResourceReader constructor causes an ArgumentException.
