怎么把这个字符串分组，然后赋给一个数组里？

怎么把这个字符串每两个字符分为一组，然后把它读到一个数组里
比如a（0）=4D，a（1）=A9...........
最后把结果输出到窗体上？
谢谢大家
字符如下：
4D5A90000300000004000000FFFF0000B800000000000000400000000000000000000000000000000000000000000000000000000000000000000000E00000000E1FBA0E00B409CD21B8014CCD21546869732070726F6772616D2063616E6E6F742062652072756E20696E20444F53206D6F64652E0D0D0A24000000000000002B9ED5106FFFBB436FFFBB436FFFBB43ACF0B4436EFFBB436FFFBA431BFFBB43ACF0E64362FFBB43ACF0E5436EFFBB43ACF0E4437AFFBB43ACF0DB437EFFBB43ACF0E1436EFFBB43526963686FFFBB43
