我的线条由相同的两半组成,我想从其中去除一半;例如,'AbcAbc'
应该变成'Abc'
。
数据始终看起来像:

我先计算字符串中的字符数,然后将其减半,但不确定如何使用计算出的(减半)字符数来剪切原始字符串。
$vip_ip = $vip_line.("Virtual IP Address/Protocol/Port")
$half_string = $vip_ip.length /2
$ vip_ip.length 44
$ half_string 22
$vip_cut = $vip_ip.(0,-$halfstring)
答案 0 :(得分:2)
您正在尝试收集字符串方法"".SubString()
在您的情况下,您只需要这样的东西:
$vip_ip.substring(0,$halfstring)
从字符串的开始到一半。因为答案是相同的,所以也可以从一半开始到结尾。 SubString()
支持这两种重载。
$vip_ip.substring($halfstring)
