使用长文件路径时的 Get-ChildItem 错误处理 [英] Get-ChildItem error handling when using long file paths

问题描述

我正在尝试处理扫描文件夹时出现的错误.假设我有类似的东西:

I am trying to handle errors when scanning through folders. Let's say I have something like:

Get-ChildItem $somepath -Directory | ForEach-Object {
   if(error occurred due to too long path) {
        skip this folder then
   } else {
       Write-Host $_.BaseName
   }
}

当我这样做时，我会打印 $somepath 中的文件夹，直到其中一个太长，然后循环停止.即使使用 SilentlyContinue.即使到达太长的文件夹，我也想打印.

When I do this I print the folders in $somepath until one of them is too long and then the loop stops. Even when using SilentlyContinue. I want to print even after reaching a folder that is too long.

推荐答案

如果您可以安装非古老的 ​​PowerShell 版本(3.0 或更高版本)，只需在路径前加上 \\?\ 即可克服完整路径的 260 个字符限制:

If you can install a non-ancient PowerShell version (3.0 or newer), simply prepend the path with \\?\ to overcome the 260-character limit for full path:

Get-ChildItem "\\?\$somepath" | ForEach {
    # ............
}
