ascii和字符串的相互转换

            //字符串转ascii码
            MessageBox.Show(System.Text.ASCIIEncoding.ASCII.GetBytes("A")[0].ToString());
            //ascii转字符串
            ASCIIEncoding AE2 = new ASCIIEncoding();

            byte[] ByteArray2 = { 65, 97, 102 };
            char[] CharArray = AE2.GetChars(ByteArray2);

            for (int x = 0; x <= CharArray.Length - 1; x++)
            {
                MessageBox.Show(CharArray[x].ToString());
            }
