问题描述
您好，我是 PowerShell 的新手。我有一个 4 级的文件路径。
Rootedirectory\directory1\directory2\directory3\ 文件
文件结构始终保持不变。
这是我的代码，问题是它重复了相同的值
#Place Root Folder in desktop
$Fullpath = 'C:\Users\Glen Sale\Desktop\donor'
$rootDir = $Fullpath.Split('\')[4]
#Get Creationtime of matching root folder
$session = Get-ChildItem 'C:\Users\Glen Sale\Desktop' -Filter $rootDir
$organfolder = Get-ChildItem 'C:\Users\Glen Sale\Desktop\donor' -Directory
foreach ($dir in $organfolder){
Get-ChildItem $dir.FullName -File
$biospyfolder = Get-ChildItem $dir.FullName -Directory
foreach($dir2 in $biospyfolder){
gci $dir2.fullname -File
$sectionfolder = gci $biospyfolder.fullname -Directory
foreach($dir3 in $sectionfolder){
$tiffFiles= gci $dir3.fullname -File
}
}
}
function recurse {
Get-ChildItem -LiteralPath $Fullpath |
ForEach-Object {
$Obj = [ordered]@{
session_id = $session.CreationTime | Get-Date -f ("yyyyMMdd")
session_date = $session.CreationTime | Get-Date -f ("yyyy/MM/dd")
#$rootDir
organ=@{
organ_id= $organfolder.namer#[0]
biospy= @(
@{biospy_id = $biospyfolder.name#[0]
section= @(
@{section_id= $sectionfolder.name#[0]
tiff_files = $tiffFiles.name#[0]
}
)
})
}
}
} {
$Obj
}
}
recurse | ConvertTo-Json -Depth 100 #| out-file ''
我得到的输出正在被重复。 结果：
[
{
"session_id": "20210418","session_date": "2021/04/18","organ": {
"organ_id": [
"FBG01","FBG02"
],"biospy": [
{
"biospy_id": "FBG01.12.1","section": [
{
"section_id": [
"FBG01.12.1.1","FBG01.12.1.2"
],"tiff_files": [
"No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f00d0.TIF","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f00d1.TIF","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f00d2.TIF","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f00d3.TIF","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f01d0.TIF","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f01d1.TIF"
]
}
]
}
]
}
},{
"session_id": "20210418","No Sample 0.05 40X_Bottom Slide_R_p00_0_A01f01d1.TIF"
]
}
]
}
]
}
}
]
这是我想要的正确分类的结果

解决方法
它来自您编写递归函数的方式，因为 Foreach-object 具有特殊的语法。
看：
1..3| foreach-object {$n=0}{$a=$n++}{$a}
给出：
3
第一个脚本块是在循环之前发起者执行一次，第二个是循环执行次数与对象数量相同，第三个是在结束时执行一次。
但你只用了两个
1..3| foreach-object {$a=$n++}{$a}
给出：
3
3
3
第一个脚本块启动器执行一次，循环 {$obj} 执行多次。
我使用类和嵌套循环找到了解决我的问题的方法
class section
{
[System.String]$section_id = ''
[System.String[]]$tiff_files = @()
}
class biopsy
{
[System.String]$biopsy_id = ''
[section[]]$section = @()
}
class organ
{
[System.String]$organ_id = ''
[biopsy[]]$biopsy = @()
}
class session
{
[System.String]$session_id = ''
[System.String]$session_date = ''
[organ[]]$organ = @()
}
$session = [session]@{
session_id = 'session_id'
session_date = 'session_date'
}
foreach($o in Get-ChildItem -Directory -Path C:\Users\v-mtouri\Desktop\donor)
{
$organ = [organ]@{organ_id = $o.Name}
$session.organ += $organ
foreach ($b in Get-ChildItem -Directory -Path $o.FullName)
{
$biopsy = [biopsy]@{biopsy_id = $b.Name}
$organ.biopsy += $biopsy
foreach ($s in Get-ChildItem -Directory -Path $b.FullName)
{
$section = [section]@{
section_id = $s.Name
tiff_files = Get-ChildItem -File -Path $s.FullName | Select-Object -ExpandProperty Name
}
$biopsy.section += $section
}
}
