Splitting a string into separate variables
提问by davetherave
I have a string, which I have split using the code $CreateDT.Split(" "). I now want to manipulate two separate strings in different ways. How can I separate these into two variables?

An array is created with the -splitoperator. Like so,
使用-split运算符创建数组。像这样，
$myString="Four score and seven years ago"
$arr = $myString -split ' '
$arr # Print output
Four
score
and
seven
years
ago
When you need a certain item, use array index to reach it. Mind that index starts from zero. Like so,
当您需要某个项目时，请使用数组索引来访问它。请注意索引从零开始。像这样，
$arr[2] # 3rd element
and
$arr[4] # 5th element
years

It is important to note the following difference between the two techniques:
重要的是要注意这两种技术之间的以下区别：
$Str="This is the<BR />source string<BR />ALL RIGHT"
$Str.Split("<BR />")
This
is
the
(multiple blank lines)
source
string
(multiple blank lines)
ALL
IGHT
$Str -Split("<BR />")
This is the
source string
ALL RIGHT
From this you can see that the string.split()method:
从中可以看出该string.split()方法：
- performs a case sensitivesplit (note that "ALL RIGHT" his split on the "R" but "broken" is not split on the "r")
- treats the string as a list of possible characters to split on
- 执行区分大小写的拆分（请注意，“ALL RIGHT”他在“R”上的拆分但“broken”不会在“r”上拆分）
- 将字符串视为要拆分的可能字符列表
While the -splitoperator:
而-split运营商：
- performs a case-insensitive comparison
- only splits on the whole string
- 执行不区分大小写的比较
- 只在整个字符串上拆分

Try this:
尝试这个：
$Object = 'FirstPart SecondPart' | ConvertFrom-String -PropertyNames Val1, Val2
$Object.Val1
$Object.Val2

Foreach-object operation statement:
Foreach-object操作语句：
$a,$b = 'hi.there' | foreach split .
$a,$b
hi
there
