How to create a Dynamic IEnumerable

I know this is a simple question for you. But I am a beginner in c#. What I want to achieve is to create a method that will store any type of List of Objects from my Model. e.g List<Person>.

I have tried to make something like this..

   public IEnumerable<T> GetObjects<T>()
        {
            Type type = typeof(T);

            PropertyInfo[] properties = type.GetProperties();

            foreach (PropertyInfo item in properties)
            {
                // store properties
            }


            List<T> objects = new List<T>();

            using (SqlConnection str = GetSqlConnection)
            {
                // retrieve data from db 
                //then store it to list of objects
            }

            return objects;

        }

This will enable me to retrieve data using only this method.
