I would like to insert a soft hyphen between every letter in a word using powershell. for example here is some text:
Thisisatest => T-h-i-s-i-s-a-t-e-s-t
- is a soft hyphen. How might i do this in powershell?
回答1:
Using .NET methods a little more than canonical PowerShell code, you can write
$word = "Thisisatest"
[System.String]::Join("-", $word.ToCharArray())
and Powershell outputs "T-h-i-s-i-s-a-t-e-s-t"
EDIT: For a true soft hyphen, and using this answer on Unicode in PowerShell, I would change the second line to
[System.String]::Join([char] 0x00AD, $word.ToCharArray())
回答2:
You can use the PowerShell-friendly -join operator to do this:
"Thisisatest".ToCharArray() -join '-'
Look at the PowerShell Technet help for more information about the -join PowerShell operator.

There is a great article on splitting and joining strings in PowerShell here.
You may also find that the string.ToCharacterArray method is useful, as mentioned here.

My Prof. PowerShell column on the topic of splitting and joining: http://mcpmag.com/articles/2011/10/18/split-and-join-operators.aspx
Personally, I think you should avoid using .NET classes and methods unless there is no "native" PowerShell cmdlet or operator.
