在Powershell中将数组导出到CSV问题

Question

我有以下代码，查询MSSQL Server数据库，然后将结果与CSV比较，将CSV中与数据库中对应行不匹配的任何行添加到新CSV中，以创建仅包含以下内容的CSV更改了行并丢弃了尚未更改的行。

$priceCSV = Import-Csv C:\Users\user\Desktop\pricedelta\Products.csv

$newpriceCSV = @(,@("SKU","BrandName","ID","Name","1stCheapestDistributorName","1stCheapestDistributorPrice","1stCheapestDistributorStock","1stCheapestDistributorProductName","1stCheapestDistributorDeliveryCost","2ndCheapestDistributorName","2ndCheapestDistributorPrice","2ndCheapestDistributorStock","2ndCheapestDistributorProductName","2ndCheapestDistributorDeliveryCost","3rdCheapestDistributorName","3rdCheapestDistributorPrice","3rdCheapestDistributorStock","3rdCheapestDistributorProductName","3rdCheapestDistributorDeliveryCost","4thCheapestDistributorName","4thCheapestDistributorPrice","4thCheapestDistributorStock","4thCheapestDistributorProductName","4thCheapestDistributorDeliveryCost","5thCheapestDistributorName","5thCheapestDistributorPrice","5thCheapestDistributorStock","5thCheapestDistributorProductName","5thCheapestDistributorDeliveryCost","DescriptionType"))

####
#Checks for changed rows are here
####

$NewArray = @()
$names = @("SKU","BrandName","ID","Name","1stCheapestDistributorName","1stCheapestDistributorPrice","1stCheapestDistributorStock","1stCheapestDistributorProductName","1stCheapestDistributorDeliveryCost","2ndCheapestDistributorName","2ndCheapestDistributorPrice","2ndCheapestDistributorStock","2ndCheapestDistributorProductName","2ndCheapestDistributorDeliveryCost","3rdCheapestDistributorName","3rdCheapestDistributorPrice","3rdCheapestDistributorStock","3rdCheapestDistributorProductName","3rdCheapestDistributorDeliveryCost","4thCheapestDistributorName","4thCheapestDistributorPrice","4thCheapestDistributorStock","4thCheapestDistributorProductName","4thCheapestDistributorDeliveryCost","5thCheapestDistributorName","5thCheapestDistributorPrice","5thCheapestDistributorStock","5thCheapestDistributorProductName","5thCheapestDistributorDeliveryCost","DescriptionType")

$skip = 1

foreach($row in $newpriceCSV)
{

    if($skip -eq 1){
        $skip = 0
        continue
    }

    $obj = new-object PSObject
    for ($i=0;$i -lt 30; $i++){
        $obj | add-member -membertype NoteProperty -name $names[$i] -value $row[$i]
    }
    $NewArray+=$obj

    $obj=$null
}

$NewArray

$NewArray | Export-Csv -path "C:\Users\user\Desktop\pricedelta\NewProducts.csv" -NoTypeInformation -Encoding Unicode

数据库查询和检查以及其他所有功能都可以正常工作，但是当我尝试将结果导出到CSV时，根据我的尝试，遇到了一些不同的问题。

如果我只是简单地尝试导出-Csv $ newpriceCSV，那么我在第一行和第二行上都会出现一堆废话，然后在后面的每一行使用一系列逗号，类似于此处显示的内容： http : //sharepoint-community.net / profiles / blogs / powershell从数组到逗号分隔的文件csv-via＃

尝试在与代码所示相同的链接上找到的方法后，出现以下错误：

Unable to index into an object of type System.Management.Automation.PSObject

对于该行：

$obj | add-member -membertype NoteProperty -name $names[$i] -value $row[$i]#

真的卡住了从这里去的地方，感谢您的帮助

看起来您遇到的是概念问题，而不是技术问题。 PS教程通常将这些概念视为显而易见的，有时甚至是显而易见的。 如果您想了解发生了什么，在比您更简单的情况下，请尝试复制以下问答中提供的建议答案，看看是否获得相同的结果。
