    <p>I have a Powershell script that reads a text file with single line descriptions of shares and their properties.</p> <p>It then, for each share, adds an object to an array, with properties.</p> <p>I end up with an array of shares, many with common properties but also some that only appear on a few shares.</p> <p>When I pipe the finished array to <code>Export-CSV</code>, the resulting CSV only has columns matching the properties of the first object in the array.</p> <p>Any ideas/help gratefully received.</p> <p>Here is the code:</p> <pre><code>$shares_only = gc \\server\share\SHARES.txt | where {$_ -match '^*TYPE = DISK'} $share_index = @() $shares_only |foreach { $sharename = ($_.Split(" ")[1]) $_ -match '\([\w\s.,"=&lt;&gt;()\/\*\+\-]*\);'|out-null $shareparams = $matches[0] $paramlist = ($shareparams.Substring(1,($shareparams.Length -3))).Split(",") $obj = $null $obj = New-Object System.Object $obj | Add-Member -type NoteProperty -Name NAME -Value $sharename $paramlist | foreach { $obj ` | Add-Member -type NoteProperty -Name ($_.Split("=")[0]) -Value ($_.Split("=")[1]) } $share_index += $obj } $share_index | Select * | Export-CSV -notype \\server\share\Shares.csv </code></pre> <p>Here is the first two objects in the array as an example (using <code>$share_index[0..2]</code> to output to console):</p> <pre><code>NAME : _ACCTEST_ TYPE : DISK PREFIX : (&lt;USERCODE&gt;) AREABYTES : 184320 ACCESS : ALL FAMILY : ACCTESTPACK DOWNSIZEAREA : TRUE NAME : _HOME_ TYPE : DISK PREFIX : (&lt;USERCODE&gt;) COMMENT : Private user files AREABYTES : 184320 ACCESS : ALL -EXTRACT FAMILY : &lt;FAMILY&gt; DOWNSIZEAREA : TRUE ALLOWGUESTACCESS : TRUE </code></pre> <p>And here are the first 3 rows of the CSV:</p> <pre><code>"NAME","TYPE ","PREFIX ","AREABYTES ","ACCESS ","FAMILY ","DOWNSIZEAREA " "_ACCTEST_"," DISK "," (&lt;USERCODE&gt;) "," 184320 "," ALL "," ACCTESTPACK "," TRUE " "_HOME_"," DISK "," (&lt;USERCODE&gt;) "," 184320 "," ALL -EXTRACT "," &lt;FAMILY&gt; "," TRUE " </code></pre> <p>You can see that <code>COMMENT</code> and <code>ALLOWGUESTACCESS</code> properties are missing even although they are in the array for the <code>_HOME_</code> share.</p> <p><strong>EDIT:</strong> Accepted slightly modified version of @JPBlancs answer, so last 2 lines of my code is now:</p> <pre><code>$fixed_index = $share_index | Sort-Object -Property @{expression={(($_.psobject.Properties)|Measure-Object).count}} -Descending | ConvertTo-CSV -notype $fixed_index | ConvertFrom-CSV | Sort -Property Name | Export-CSV -notype \\server\share\Shares.csv </code></pre> <p>So, done as suggested, then converted to CSV in a new object. Then, convert that object back from CSV, retaining the new properties, sort again on Name to get the alphabetical list I need, then Export to CSV again.</p> <p>Gives me, for example:</p> <pre><code>"NAME","TYPE","PREFIX","PUBLIC","COMMENT","AREABYTES","ACCESS","FAMILY","DOWNSIZEAREA","ALLOWGUESTACCESS" "_ACCTEST_"," DISK "," (&lt;USERCODE&gt;) ","",""," 184320 "," ALL "," ACCTESTPACK "," TRUE ", "_HOME_"," DISK "," (&lt;USERCODE&gt;) ",""," Private user files "," 184320 "," ALL -EXTRACT "," &lt;FAMILY&gt; "," TRUE "," TRUE " </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
