引言

在了解hex文件格式的基礎(chǔ)上閱讀本文更佳。可閱讀下邊文章：

【HEX文件格式詳解】https://star-302.blog.csdn.net/article/details/119563635

一、需求

將hex文件的內(nèi)容轉(zhuǎn)成按地址順序（從低到高）排列的二進(jìn)制數(shù)據(jù)（bin文件）

二、編寫代碼的思路

整個(gè)過程主要分為三步：

遍歷整個(gè)hex文件，找出最小地址和最大地址（也就是起始地址和結(jié)束地址），算出數(shù)據(jù)長度（數(shù)據(jù)長度=結(jié)束地址-起始地址+1），根據(jù)得到的數(shù)據(jù)長度，分配對(duì)應(yīng)大小的內(nèi)存（開辟一個(gè)數(shù)組）；

再次遍歷整個(gè)hex文件，計(jì)算每條數(shù)據(jù)記錄中的起始地址與hex文件起始地址的偏移量，按照偏移量將該條數(shù)據(jù)記錄中的數(shù)據(jù)部分寫入第一步的數(shù)組中。（這樣就實(shí)現(xiàn)了按照從低到高的地址順序排列整個(gè)hex文件的數(shù)據(jù)）。

最后只需要將該數(shù)組寫出到文件中即可。

三、代碼實(shí)現(xiàn)【C#】
