【问题描述】：

当A列的值（即DevID）等于B列的值（即ProdID）时，需要删除CSV文件的整行

我的代码：

$MergedFile= Import-Csv "C:\Users\d-mansings\Desktop\Mergedata.csv"

 $MergeTable=@{} 
   foreach($line in $MergedFile){
    if(Compare-Object $line.DevID $line.ProdID){
    echo "Not Matched, Keep the file as it"}
    else{ echo "Row need to be deleted"}
        }

我需要一个可以删除整行的命令来代替 Row need to be deleted。

以下是我的CSV 文件：

"DevID","ProdID","cfname"
"-----","-----","------"
"10201","10202","Risk ID"
"10202","20202","Issue ID"
"10203","20203","Dependency ID"
"10204","20204","Server ID"
"10205","20205","Parent Application ID"
"10206","20206","Application Service ID"
"10207","20207","Application Supportability"
"10208","20208","Application Compatibility"
"10300","20300","Application Status"
"10301","20302","Contact ID Type 2"
"10302","20302","Contact ID Type 3"
"10303","20303","Contact ID Type 4"
"10304","10304","Business Service Manager"
"10308","20308","Server Location Name:"

【解决方案1】：

您可以使用Where-Object cmdlet 过滤所有DevID 不等于ProdID 的条目，并将结果通过管道传送到Export-Csv cmdlet 以将csv 保存回来：

Import-Csv 'source.csv' | 
    Where { $_.DevID -ne $_.ProdID } | 
    Export-Csv -Path 'destination.csv' -NoTypeInformation

输出：

"DevID","ProdID","cfname"
"10201","10202","Risk ID"
"10202","20202","Issue ID"
"10203","20203","Dependency ID"
"10204","20204","Server ID"
"10205","20205","Parent Application ID"
"10206","20206","Application Service ID"
"10207","20207","Application Supportability"
"10208","20208","Application Compatibility"
"10300","20300","Application Status"
"10301","20302","Contact ID Type 2"
"10302","20302","Contact ID Type 3"
"10303","20303","Contact ID Type 4"
"10308","20308","Server Location Name:"
