最基础的方式            string test = "00282ED47E33";
            StringBuilder sb = new StringBuilder(test[0].ToString());
            for (int i = 1; i < test.Length; i++)
            {
                if (i % 2 == 0)
                {
                    sb.Append("-");
                    sb.Append(test[i]);
                }
                else
                {
                    sb.Append(test[i]);
                }
            }
            richTextBox2.Text = sb.ToString();
