Converting the FileSystemObject's GetStandardStream Method


Windows PowerShell


Definition: Returns a string (TextStream object) that corresponds to StdIn, StdOut, or StdErr

GetStandardStream


PowerShell provides cmdlets to read from and write to the console. To read from StdIn, use the Read-Host cmdlet:


PS C:\scripts> Read-Host
Typing in some standard input
Typing in some standard input


To write to StdOut, use the Write-Host cmdlet:


PS C:\scripts> $a = "A text string to output"
PS C:\scripts> Write-Host $a
A text string to output


Of course, be default all output from PowerShell commands goes to the console. So this also works:


PS C:\scripts> $a = "A text string to output"
PS C:\scripts> $a
A text string to output


We’re not sure why you’d do this instead of using the cmdlets, but you can read and write input to and from the console by using the .NET Framework System.Console class.

This command reads StdIn, meaning that when you run this command it will wait for input from the console before PowerShell will continue:


PS C:\scripts> [System.Console]::ReadLine()
Typing in some standard input
Typing in some standard input


Here’s an example of writing specifically to StdOut:


PS C:\scripts> $a = "A text string to output"
PS C:\scripts> [system.console]::writeline($a)
A text string to output
