根据规则（在下面的代码中注释），文件将被过滤，并为每个ResultName添加一个新行。

这里：我不知道如何将$ newRow附加到我的$ fileData

示例所需输出：

问题如何将$ newRow变量附加到$ fileData以便将所有值导出到文件？

Answer 1

而不是Write-Host $newRow只需输出新对象$newRow即可将其附加到$ filedata。顺便说一句，你的代码几乎无法读取，我会加强它。

使用您的上述示例数据，此代码为：

$file = gci "q:\test\2018\03\27\sample.*"
$fileData = Import-Csv $file.FullName | Group-Object ResultName | Foreach-Object {
    $Ten = $_.Group | Where-Object { $_.TypeIndicator -eq '10' }
    $ND =  $_.Group | Where-Object { $_.TypeIndicator -eq 'ND' }

    # Case 1: If Indicator is null or ! for /10 and Indicator is null or ! for ND  
    #         Select line ND and create new row with ResultName + estimated Eg."Al estimated" with ResultEntry = ''
    if(('!','' -contains $Ten.Indicator) -and ('!','' -contains $ND.Indicator)) {
        $ND

        #create new row
        $newRow = New-Object PsObject -Property @{'SampleNumber' = $ND.SampleNumber;
                                                  'TypeIndicator'= $ND.TypeIndicator;
                                                  'ResultName'   = $ND.ResultName + ' estimated' ;
                                                  'Indicator'    = $ND.Indicator ; 
                                                  'ResultEntry'  = '' 
                                                 } 

    #Case 2: If Indicator is null/! for 10 and Indicator is not null for ND. 
    # Select line ND and create new row with ResultName + estimated Eg."Al estimated" with ResultEntry = ''
    } elseif (('!','' -contains $Ten.Indicator) -and ('o','u' -contains $ND.Indicator)) {
        $Ten
        $newRow = New-Object PsObject -Property @{'SampleNumber' = $Ten.SampleNumber; 
                                                  'TypeIndicator'= $Ten.TypeIndicator;
                                                  'ResultName'   = $Ten.ResultName + ' estimated' ;
                                                  'Indicator'    = $Ten.Indicator ; 
                                                  'ResultEntry'  = '' 
                                                  }  
    }

     #Case 3: If Indicator contains either 'o' or 'u' for 10 and Indicateur is null/! for ND 
     # select line ND and create a new row with ResultEntry = ''
    elseif (('o','u' -contains $Ten.Indicator) -and ('!','' -contains $ND.Indicator)) {
        $ND  
        $newRow = New-Object PsObject -Property @{'SampleNumber'  = $ND.SampleNumber; 
                                                   'TypeIndicator'= $ND.TypeIndicator;
                                                   'ResultName'   = $ND.ResultName;
                                                   'Indicator'    = $ND.Indicator ; 
                                                   'ResultEntry'  = '' 
                                                  }   
    }

     #Case 4: If both /10 and ND contains either o or u, Select line /10
     # select line 10 and create a new row with ResultEntry = ''
    elseif (('u','o' -contains $Ten.Indicator) -and ('o','u' -contains $ND.Indicator)) {
        $Ten

        $newRow = New-Object PsObject -Property @{'SampleNumber' = $Ten.SampleNumber; 
                                                  'TypeIndicator'= $Ten.TypeIndicator;
                                                  'ResultName'   = $Ten.ResultName;
                                                  'Indicator'    = $Ten.Indicator ; 
                                                  'ResultEntry'  = '' 
                                                 }  
    }
    $newRow
    # Write-Host $newRow #PROBLEM HERE: I dont know how to get this $newRow appended to my $fileData 
}
$fileData | Format-Table

会给你这个输出：

SampleNumber TypeIndicator ResultName   Indicator ResultEntry
------------ ------------- ----------   --------- -----------
111          10            S                      125.234
