最近在写一个C#的嵌入式打印机的demo
遇到一个问题
因为我们研发给出指令是16进制，但前面没有0x，写代码时需要在前面增加0x
在csdn上面搜了一下，发现有用txt增加的或者是notepad++ 16进制数字加前缀0x

我学习了一下
txt增加的比较麻烦一点，需要手动分行
如下

一、TXT 内容 每行 批量加后缀 方法如下：
目标TXT文件：1.txt (需要给每行加后缀的文件名称)
复制如下代码在新建TXT文档中，保存TXT文档，重新命名为houzhui.bat

@echo offfor /f "tokens=*" %%i in (1.txt) do echo %%i后缀>>$move $ 1.txt

执行 houzhui.bat 文件

二、TXT 内容 每行 批量加前缀 方法如下：
复制如下代码在新建TXT文档中，保存TXT文档，重新命名为qianzhui.bat

@echo offfor /f "tokens=*" %%i in (1.txt) do echo 前缀%%i>>$move $ 1.txt

执行 qianzhui.bat 文件

三、notepad++ 16进制数字加前缀0x

1.利用notepad++的正则表达式替换功能

00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f f0 f1 f2 f3 f4 f5 f6 f7 f8 f9 fa fb fc fd fe ff

正则搜索串([0-9a-fA-F]{2}),替换串0x\1,结果:


结果中间有个小红点，这个在vs里面是非法的“ ”

后面反向替换，搜索串0x([0-9a-fA-F]{2}),替换串 \1,结果:

这个就不会报错

};sp.Write(ESCALT_2, 0, 1000);}

感觉这个还是能提高效率的
