Windows PowerShell क्या है और यह क्या खाता है? भाग 4: वस्तुओं, कस्टम कक्षाओं के साथ काम करना

विषय - सूची:

PowerShell

ऑब्जेक्ट संरचना देखें

Get-Process | Get-Member

Get-Process | Get-Member -MemberType Property

वस्तु छानना

Where-Object {   }

Get-Service | Where-Object {$_.Status -eq "Stopped"}

Get-Service | Where-Object {$_.Status -eq "Stopped"} | Get-Member

वस्तुओं को क्रमबद्ध करें

Get-Process | Sort-Object –Property cpu

Get-Process | Sort-Object cpu -Descending

वस्तुओं और उनके भागों का चयन

Get-Process | Sort-Object WS -Descending | Select-Object -First 10

Get-Process | Select-Object ProcessName, Id -First 1

Get-Process | Select-Object ProcessName, Id -First 1 | Get-Member

$obj = Get-Process | Select-Object ProcessName, Id -First 1
$obj.GetType()

Get-Process | Select-Object -Property ProcessName, @{Name="StartTime"; Expression = {$_.StartTime.Minute}}

Get-Process | Select-Object -Property ProcessName, @{Name="StartTime"; Expression = {$_.StartTime.Minute}} | Get-Member

फॉरएच-ऑब्जेक्ट, ग्रुप-ऑब्जेक्ट और माप-ऑब्जेक्ट

ForEach-Object {   }

Group-Object PropertyName

Measure-Object -Property PropertyName -Minimum -Maximum -Average -Sum

.NET और COM ऑब्जेक्ट बनाना (नई-वस्तु)

New-Object -TypeName System.Diagnostics.EventLog

$AppLog = New-Object -TypeName System.Diagnostics.EventLog -ArgumentList Application
$AppLog

$AppLog | Get-Member -MemberType Method

$AppLog.Clear()

New-Object -ComObject WScript.Shell
New-Object -ComObject WScript.Network
New-Object -ComObject Scripting.Dictionary
New-Object -ComObject Scripting.FileSystemObject

स्थैतिक तरीके से कॉल करना

[System.Environment] | Get-Member

[System.Environment] | Get-Member -Static

[System.Environment]::OSVersion

$test=[System.Math]::Sqrt(25) 
$test
$test.GetType()

PSCustomObject टाइप करें

$object = New-Object  –TypeName PSCustomObject -Property @{Name = 'Ivan Danko'; 
                                          City = 'Moscow';
                                          Country = 'Russia'}

$object | Get-Member

$object = [PSCustomObject]@{Name = 'Ivan Danko'; 
                                          City = 'Moscow';
                                          Country = 'Russia'
}

$object.Name

$object.'Name'

$value = 'Name'
$object.$value

$hash = @{'Name'='Ivan Danko'; 'City'='Moscow'; 'Country'='Russia'}
$hash.GetType()
$object = [pscustomobject]$hash
$object.GetType()

$object = [PSCustomObject][ordered]@{Name = 'Ivan Danko'; 
                                          City = 'Moscow';
                                          Country = 'Russia'
}

$object | Add-Member –MemberType NoteProperty –Name Age  –Value 33
$object | Get-Member

$ScriptBlock = {
    #  
}
$object | Add-Member -Name "MyMethod" -MemberType ScriptMethod -Value $ScriptBlock
$object | Get-Member

$object.psobject.properties.remove('Name')

अपनी खुद की कक्षाएं बनाना

class MyClass
{
    #  
}

class MyClass 
{
     [string]$Name
     [string]$City
     [string]$Country
}

$object = New-Object -TypeName MyClass

$object = [MyClass]::new()

$object | Get-Member

$object.Name = 'Ivan Danko'
$object.City = 'Moscow'
$object.Country = 'Russia'
$object

class Example
{
     [string]$Name = 'John Doe'
}

class MyClass 
{
     [string]$Name
     [string]$City
     [string]$Country
     
     # 
     Smile([bool]$param1)
     {
         If($param1) {
            Write-Host ':)'
         }
     }
}

$object = [MyClass]::new()
$object.Smile($true)

class MyClass2 : MyClass
{
      #  ,     MyClass
}
[MyClass2]::new().Smile($true)
