powershell - New-Item error in powershell

Question

I found this interesting behavior. Why could this happen

I am using the cmdlet New-Item for create a folder. If I write something like this it works

New-Item "D:\logeando9091" -type directory 

I have a variable of type string. It contains the value of the path where I want the new folder.

Why when Use New-Item with this variable it fails?

New-Item $settings.get_Item("LogFolder") -type directory

Here is a screenshot

无论出于何种原因，您的字符串都包含双引号，所以这当然不起作用。删除它们，您应该会很好：

$logFolder = $settings.get_Item("LogFolder") -replace '^"|"$'
mkdir $logFlder

不过，您可能应该修复读取设置的代码。

另一种方法是使用Invoke-Expression，但我不推荐它。最好避免它。
