Question

我正在尝试解析，附加ip和子网掩码地址。解析工作正常但附加会给我带来问题。在这里，我正在粘贴我的代码。基本上我正在获取IP和子网掩码，然后做一些掩码然后追加。

假设我有以下内容，

IPADDR : 10.239.230.47
SUBNET : 255.255.254.0

我得到这样的输出：

-----------------------------------------------------------------
255.255.254.0
"10.239.231                                                     .255"
Press any key to exit
-----------------------------------------------------------------------

我无法解决为什么我得到空间btw.Please帮助我。

Answer 1

set c1=%c1% 
           ^ There is a space here being added

最好使用

set "c1=%c1%"

将避免此问题

解析并附加ip和子网掩码地址
