Why does Get-Date seem to return DateTime objects, but the BinarySerializer indicate it returns a PSObject?

netsh result to powershell object

由 流过昼夜 提交于 2019-12-02 15:32:34
问题 I am trying to work with netsh from powershell . I want see result from this command such as object, but netsh return string: netsh wlan show hostednetwork | Get-Member TypeName: System.String ... My script must work on system with rather localization, and I can't use -match for parse string to object directly. How I can solve my trouble? 回答1: You got a few alternatives, none of which are nice. 1) Read the netsh output into a string[] and use a custom record parser to create your own object.

Say I've a psobject like this : $o=New-Object PSObject -Property @{"value"=0} Add-Member -MemberType ScriptMethod -Name "Sqrt" -Value { echo "the square root of $($this.value) is $([Math]::Round([Math]::Sqrt($this.value),2))" } -inputObject $o Is it possible to attach an event so that the method Sqrt() is executed when the value attribute change ? ie : PS>$o.value=9 will produce the square root of 9 is 3 update As per @Richard answer this is the working recipe : $o=New-Object PSObject -property @{"_val"=1} Add-Member -MemberType ScriptMethod -Name "Sqrt" -Value { write-host "the square root of

Unexected results in Receive-Job

问题 I noticed weird behavior when using jobs in PowerShell 5.0. Running job that returns PSObject , also returns some hashtable. Jobs that return strings, integers, etc work propertly. Running Start-Job { New-Object PSObject -Property @{ A = 1 } } | Receive-Job -Wait -AutoRemoveJob returns A : 1 RunspaceId : 6921e85f-301e-4e95-8e4b-c0882fc2085f PSSourceJobInstanceId : 2992ef77-5642-4eac-8617-f26449a87801 Running Start-Job { New-Object PSObject } | Receive-Job -Wait -AutoRemoveJob returns @

Difference between PSObject, Hashtable, and PSCustomObject

由 冷暖自知 提交于 2019-11-30 11:24:13
问题 Can anybody explain the details? If I create an object using $var = [PSObject]@{a=1;b=2;c=3} and then I look for its type using getType() PowerShell tells me it's of type Hashtable . When using Get-Member (alias gm ) to inspect the object it's obvious that a hashtable has been created, since it has a keys and a values property. So what's the difference to a "normal" hashtable? Also, what's the advantage of using a PSCustomObject? When creating one using something like this $var =
