如何按 Powershell 中的一个属性值对对象数组进行排序？

Question

For example, I have a variable, which returns the line with several arrays:

@{sourceDSAcn=B; LastSyncResult=0} @{sourceDSAcn=A; LastSyncResult=9} @{sourceDSAcn=C; LastSyncResult=0} @{sourceDSAcn=M; Last SyncResult=10}

I want to sort this line alphabetically by one of parameters. In this case - by sourceDSAcn , so result must be like that:

@{sourceDSAcn=A; LastSyncResult=9} @{sourceDSAcn=B; LastSyncResult=0} @{sourceDSAcn=C; LastSyncResult=0} @{sourceDSAcn=M; Last SyncResult=10}

How can I do that?

Your output format suggests two things:

• The objects aren't arrays , but custom objects ( [pscustomobject] instances).

• You've used the Write-Host cmdet to print these objects to the host (display), which results in the hashtable-literal- like representation shown in your question (see this answer ).

  • If, instead, you want the usual rich display formatting you get by default - while still sending the output to the host only rather than to the success output stream - you can use the Out-Host cmdlet.
  • Conversely, to produce data output to the pipeline , use either the Write-Output cmdlet or, preferably, PowerShell's implicit output feature, as shown below; for more information, see this answer .

In order to sort (custom) objects by a given property , simply pass the name of that property to
Sort-Object 's (positionally implied) -Property parameter, as Mathias R. Jessen helpfully suggests:

# Using $variable by itself implicitly sends its value through the pipeline.
# It is equivalent to: Write-Output $variable | ...
$variable | Sort-Object sourceDSAcn # same as: ... | Sort-Object -Property sourceDSAcn
