found this helpful for a project

had some issues in the PR version ... this is what I am actually using ... sorry about that
somehow caching the regex's would be a nice performance boost

        private bool IgnoreObjectName(string name, string path, CloneConfiguration configuration, ICollection<string> ignorePropertiesOrPaths, IEnumerable<CustomAttributeData> attributes = null)
        {
            if (ignorePropertiesOrPaths == null || ignorePropertiesOrPaths.Count == 0)
                return false;

            if (ignorePropertiesOrPaths?.Contains(name) == true || ignorePropertiesOrPaths?.Contains(path) == true)
                return true;

#if FEATURE_CUSTOM_ATTRIBUTES
            if (attributes?.Any(x => configuration.IgnorePropertiesWithAttributes?.Contains(x.AttributeType.Name) == true) == true)
                return true;
#else
            if (attributes?.Any(x => configuration.IgnorePropertiesWithAttributes?.Contains(x.Constructor.DeclaringType.Name) == true) == true)
                return true;
#endif

            if (ignorePropertiesOrPaths != null)
            {
                var ignorePropertiesOrPathsRe = ignorePropertiesOrPaths.Select(x => (x.Length > 2 && x.StartsWith("/") && x.EndsWith("/")) ? x.Substring(1, x.Length - 2) : "").Where(x => x.Length > 0).ToList();
                foreach (var re in ignorePropertiesOrPathsRe)
                {
                    var rx = new System.Text.RegularExpressions.Regex(re);
                    if (!String.IsNullOrEmpty(name) && rx.IsMatch(name))
                        return true;
                    if (!String.IsNullOrEmpty(path) && rx.IsMatch(path))
                        return true;
                }
            }

            return false;
        }
