The topic is closed, I figured it out myself. did like this:

List<SqlDbType> types = new List<SqlDbType>();
            foreach (SqlDbType item  in Enum.GetValues(typeof(SqlDbType)))
            {
                types.Add(item);
            }
            SqlDbType[] list = types.ToArray();

            foreach(var item in list)
            {
                comboBox1.Items.Add(item);
            }
