Answer 1

    static void Main(string[] args) {

        foreach (System.Reflection.PropertyInfo propertyInfo in typeof(System.Collections.ArrayList).GetProperties()) {

            System.Reflection.ParameterInfo[] parameterInfos = propertyInfo.GetIndexParameters();
            // then is indexer property
            if (parameterInfos.Length > 0) {
                System.Console.WriteLine(propertyInfo.Name);
            }
        }


        System.Console.ReadKey();
    }
