因此,我从经验中知道,从cmd.exe运行有效程序并检查%errorlevel%将返回0:

C:\>dir logo.bmp
 Volume in drive C has no label.
 Volume Serial Number is 5283-A7A2

 Directory of C:\

05/22/2008  12:43 PM         1,440,054 logo.bmp
               1 File(s)      1,440,054 bytes
               0 Dir(s)  71,723,995,136 bytes free

C:\>echo %errorlevel%
0


同样,尝试执行一个不存在的命令,然后检查%errorcode%会给我9009:

C:\>idontexist.exe
'idontexist.exe' is not recognized as an internal or external command,
operable program or batch file.

C:\>echo %errorlevel%
9009


我已经编写批处理脚本多年了,它们一直都以这种方式工作。但是,有人问到有关此技术的兼容性(向前和向后)的问题,当找不到文件或程序时,我找不到Microsoft的任何正式文档,它们实际上将9009定义为错误级别。我最近到达的是该站点(http://msdn.microsoft.com/en-us/library/ms681381(v=vs.85).aspx),不幸的是,该站点将9009列为DNS错误。

有谁知道Microsoft在哪里记录了此行为?

最佳答案

Exchange团队推出了Common Error Lookup Tool,它将为您翻译错误代码(包括HRESULTs,这非常方便)。 9009的输出是:

...所以您要寻找的是cmdmsg.h。

本质上,它并不是真正的文档,但至少是官方的。
