有幾個命令列小程式支援使用哈希表來建立自定義或計算屬性。 您通常會使用Select-Object和Format-Table來看到此專案。 哈希表具有特殊語法,在完全展開時看起來像這樣。 PowerShell $property= @{ Name ='TotalSpaceGB'Expression = { ($_.Used +$_.Free) /1GB } } ...
$PSCustomObject.Where({$_.foo-gt0}) Output foo --- 1 从PSMethod 到委托的转换 可以将PSMethod转换为委托。 这样,就可以将PSMethod[M]::DoubleStrLen作为委托值传递到[M]::AggregateString: PowerShell class M { static [int] DoubleStrLen([string]$value) {return2*$value.Length } static [long...

Enter an expression or a property. TheGroupByparameter expects that the objects are sorted. Use theSort-Objectcmdlet before usingFormat-Tableto group the objects. The value of theGroupByparameter can be a new calculated property. The calculated property can be a script block or a hash table. ...
There’s lots of punctuation, lots of structure, and you have to understand a lot about what Select-Object is doing with those three hashtables. It’s basically generating custom properties using a syntax unique to that cmdlet (and shared by the Format cmdlets). You’ll see that syntax ...
