问题 I am using this code to execute remote code (MSI installs) on a server. Passing double quote through the script is just not working. I tried two variations as given below (#3 and #4) along with the outputs. Input #1 (Simple case to test double quotes in the command) powershell.exe -inputformat none -File client.ps1 -target 1.2.3.4 -port 5985 -password "pass" -username "user" -command "echo hello" Output (Works) hello Input #2 (Understandable, this won't work) powershell.exe -inputformat none

问题 I have a form in which as soon as ready several elements will be added (for example, a list). It may take some time to add them (from fractions of a second to several minutes). Therefore, I want to add processing to a separate thread (child). The number of elements is not known in advance (for example, how many files are in the folder), so they are created in the child stream. When the processing in the child stream ends, I want to display these elements on the main form (before that the form

问题 I am really at beginner level for working with commandlets and powershell stuff. I am invoking commandlets from C# using PowerShell API. I saw strange behaviours. While on different threads on stackoverfow, people explicitly importing modules using Import-Command or PSImportModule method, I can see if there is an assembly at $env:PSModulePath available already, it is automatically loaded. Does this behaviour is by default or due to criteria configurations which i m overlooking. I am running

问题 While working with a script that uses a RunSpace, I found that it takes up more and more system memory. As far as I understand, this is due to the fact that open RunSpace do not close when completed. They remain in memory, accumulating megabytes. How to close the RunSpace, correctly? However, I do not know how long it will take - 1 second or 1 hour. Closes itself when completed. As an example, I will give arbitrary scripts. The first script is how I do the closing of the RunSpace as it is

问题 I've been searching for a way to pass events between different runspaces and yet have not found any. The following snipped creates a background runspace, which shows a small window with only one button. OnClick it shall post an event that the main runspace should receive: $Global:x = [Hashtable]::Synchronized(@{}) $x.Host = $Host $Global:rs = [RunspaceFactory]::CreateRunspace() $rs.ApartmentState,$rs.ThreadOptions = "STA","ReUseThread" $rs.Open() $rs.SessionStateProxy.SetVariable("x",$x)

问题 the [Powershell]::create() - method creates a new PowerShell-"Instance" either in the "current or a new runspace". Can someone explain how the terms process , instance , runspace and (maybe thread ) relate to each other in this regard. In laymen's terms if possible? 回答1: You can think of [Powershell]::Create() as a new powershell session on the separate thread. This session will have some default runspace created but you can change it to another one. Unlike Start-Process (separate process)
