  • powershell - Array. Add vs += - Stack Overflow
    @Preza8: (New-Object System Collections Generic List[string]) GetType() Name yields List`1 for me, as expected; perhaps you applied += to the variable containing the list (rather than calling the Add() method), in which case the variable value would indeed be converted to an array (System Object[])
  • PowerShell array initialization - Stack Overflow
    As you might guess, any approach that uses an explicit PowerShell loop is slower than those that use Net constructors or PowerShell operators (which would be compiled in IL or native code) Summary New-Object and @(somevalue)*n are fast (around 20k ticks for 100k elements)
  • powershell - Why should I avoid using the increase assignment operator . . .
    Changing the array initialization <Variable> = @() to something like: <Variable> = [Collections Generic List[Object]]::new() is not enough to resolve this performance issue because as soon as you use the + or += operator on it, it will be changed back to an immutable array type
  • How do I dynamically add elements to arrays in PowerShell?
    It's a PowerShell question, not PHP PHP arrays are significantly different to PowerShell arrays since PowerShell arrays are a fixed length To "add" to a PowerShell array, under the hood it basically creates a new array with the new length and copies every element to it I believe in PHP they are dynamic (more like a PowerShell Generic list)
  • Removing duplicate values from a PowerShell array
    Whether you're using SORT -UNIQUE, SELECT -UNIQUE or GET-UNIQUE from Powershell 2 0 to 5 1, all the examples given are on single Column arrays
  • powershell - create array from string or variable - Stack Overflow
    I need in an array everything from name1 thru name7 I attempted without success trying to convert it to a CSV using delimiter : , tried creating a PSObject , and a few other ways that didn't get me the result I was looking for
  • What does the @ symbol do in PowerShell? - Stack Overflow
    To create an array, we create a variable and assign the array Arrays are noted by the "@" symbol Let's take the discussion above and use an array to connect to multiple remote computers:
  • Select the values of one property on all objects of an array in . . .
    Both the input collection and output array must fit into memory as a whole If the input collection is itself the result of a command (pipeline) (e g , (Get-ChildItem) Name), that command must first run to completion before the resulting array's elements can be accessed
