Get-ChildItem.Length错误 [英] Get-ChildItem.Length is Wrong

问题描述

我正在编写一个递归函数，该函数遍历目录并复制其中的每个文件和文件夹.我在函数中进行的第一项检查是查看传入的路径是否有子级.为了找出答案，我使用以下方法:

I am writing a recursive function that goes through a directory and copies every file and folder in it. The first check I have in the function is to see if the path passed in has children. To find this out, I use the following method:

[array]$arrExclude = @("Extras")
Function USBCopy
{
Param ([string]$strPath, [string]$strDestinationPath)
    try
    {
        $pathChildren = Get-ChildItem -Path $strPath
        if($pathChildren.Length -gt 0)
        {
            foreach($child in $pathChildren)
            {
                if($arrExclude -notcontains $child)
                {
                    $strPathChild = "$strPath\$child"
                    $strDestinationPathChild = "$strDestinationPath\$child" 
                    Copy-Item $strPathChild -Destination $strDestinationPathChild
                    USBCopy $strPathChild $strDestinationPathChild  
                }   
            }
        }              
    }
    catch
    {
        Write-Error ("Error running USBCopy: " + $Error[0].Exception.Message)
    }    
}

在大多数情况下，我的函数都可以工作，但是我的代码会说一个目录中实际上有1个文件时该目录为空.当我调试函数时，变量会说该文件夹有子文件夹，但变量的长度为0.有人知道如何解决这个问题吗?

For the most part my function works, but my code will say a directory is empty when it actually has 1 file in it. When I debug my function, the variable will say that the folder has children but the variable's length is 0. Anyone know how to get around this?

推荐答案

尝试使用$pathChildren.Count而不是$pathChildren.Length-这将返回数组中的项目数.

Try $pathChildren.Count instead of $pathChildren.Length - that will return the number of items in the array.
