C#程序總會生成bin和obj文件夾，為了減小源碼的大小，就有必要將這兩個文件夾刪除，於是想到用批處理文件來刪除。
以下是批處理的代碼:
@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、批處理中兩個半角冒號開頭表示注釋掉這一行
2、將以上代碼復制到記事本中，並且命名為bat后綴的文件，如clear.bat.
3、clear.bat最好放到要執行刪除操作的目錄(或上層目錄)
如果只要刪除某個文件，可以將for /r %nowPath% %%i in (obj,bin) do (IF EXIST %%i RD /s /q %%i) 這一句去掉，然后將for /r %nowPath% %%i in (*.pdb,*.vshost.*) do (del %%i) 這一句中的(*.pdb,*.vshost.*)改成要刪除的文件。

我自己稍微修改和優化了下上面的代碼，如下：

優化3
優化了顯示待刪除文件或文件的總大小
優化了受set只支持32位的限制，可以支持大數字的加法運算
優化支出中文路徑的文件大小的計算。
