Question

我正在尝试编写一个P / S脚本，其中搜索并处理了一组扩展，但是我遇到了文件搜索问题。

这是我的findFiles函数 -

function findFiles([string]$extension)
{
## find all files in the working directory with the fileTypes extensions
    Write-Host "in findFiles with extension" $extension
    $dotExt = "." + $extension
    $a = Get-ChildItem -Path "." -recurse | where {$_.extension -eq $dotExt} | Foreach-Object { $_.FullName }   
    Write-Host "$array length is " $a.length
    for ($i=0; $i -lt $a.length; $i++) {
        Write-Host "test: " $a[$i]
        #findVariables($a[$i])
    }
}

因此，当找到多于1个文件时，结果看起来很好，其中每个元素包含完整路径和文件名。但是，当只找到一个对象/文件时，该数组现在每个元素存储1个字符。以下是找到的2个配置文件的示例输出，只找到了一个xml类型。如果我添加另一个xml类型的文件，它可以正常工作。

在将值存储在其中之前，只需将$a声明为数组即可。 PowerShell旨在自动进行类型转换。因此，当您将数组推入其中时，$a将成为一个数组。当您只推送一个值时，PowerShell会将其确定为字符串。

在使用之前在函数中声明$a = @()或者像@PetSerAl建议的那样，并在运行中声明它。

Powershell数组元素是get-childitem的结果
