The code below will demonstrate usage of the Synchronized variable for Runspaces. You can use any ip/hostname for $ComputerName as long it's accessible, Powershell remoting is verified by Enter-PSSession and also you added credential to Windows Credential Manager for $ComputerName as host.
Get-Runspace|?Id-NE 1|%{ $_.close(); $_.dispose()}
$Runspace = $powerShell = $connectionInfo = $handle = $hash = $null
$ComputerName ='192.168.0.3'
$hash =[hashtable]::Synchronized(@{})
$hash.One=1Write-host ('Value of $Hash.One before background runspace is {0}'-f $hash.one)-ForegroundColorGreen-BackgroundColorBlack
$Uri =New-ObjectSystem.Uri("http://$($ComputerName):5985/wsman")
$connectionInfo =New-ObjectSystem.Management.Automation.Runspaces.WSManConnectionInfo-ArgumentList $Uri
$connectionInfo.AuthenticationMechanism=[System.Management.Automation.Runspaces.AuthenticationMechanism]::Negotiate
$connectionInfo.OpenTimeout=3000
$Runspace =[runspacefactory]::CreateRunspace($connectionInfo)# don't work#$Runspace = [runspacefactory]::CreateRunspace() # works
$runspace.Open()
$runspace.SessionStateProxy.SetVariable('Hash',$hash)
$powershell =[powershell]::Create()
$powershell.Runspace= $runspace
$powershell.AddScript({
$hash.one++})|Out-Null#The Out-Null at the end is used to prevent the output of the object that occurs.
$handle = $powershell.BeginInvoke()While(-Not $handle.IsCompleted){Start-Sleep-Milliseconds100}
$powershell.EndInvoke($handle)
$runspace.Close()
$powershell.Dispose()Write-host ('Value of $Hash.One after background runspace is {0}'-f $hash.one)-ForegroundColorGreen-BackgroundColorBlackAs soon as I replace:
$Runspace =[runspacefactory]::CreateRunspace()with
$Runspace =[runspacefactory]::CreateRunspace($connectionInfo)(because I want to execute code at the remote computer), the synchronized variable $hash is not updated. Anyone know what I missing? This feature is really important and useful and I need it to make it work for remote runspaces.
