快速删除C#项目中的bin和obj文件夹的方法

C#程序总会生成bin和obj文件夹，为了减小源码的大小，就有必要将这两个文件夹删除，于是想到用批处理文件来删除。

 

以下是批处理的代码:

@echo off
set nowPath=%cd%
cd /
cd %nowPath%

::delete specify file(*.pdb,*.vshost.*)
for /r %nowPath% %%i in (*.pdb,*.vshost.*) do (del %%i)

::delete specify folder(obj,bin)
for /r %nowPath% %%i in (obj,bin) do (IF EXIST %%i RD /s /q %%i)

echo OK
pause

注：
1、批处理中两个半角冒号开头表示注释掉这一行
2、将以上代码复制到记事本中，并且命名为bat后缀的文件，如clear.bat.
3、clear.bat最好放到要执行删除操作的目录(或上层目录)

如果只要删除某个文件，可以将for /r %nowPath% %%i in (obj,bin) do (IF EXIST %%i RD /s /q %%i) 这一句去掉，然后将for /r %nowPath% %%i in (*.pdb,*.vshost.*) do (del %%i) 这一句中的(*.pdb,*.vshost.*)改成要删除的文件。

我自己稍微修改和优化了下上面的代码，如下：

 优化3

优化了显示待删除文件或文件的总大小

优化了受set只支持32位的限制，可以支持大数字的加法运算

优化支出中文路径的文件大小的计算。
