在C＃中运行Powershell并捕获返回值 [英] Running Powershell within C# and capturing return value

问题描述

大家好，



我创建了一些C＃代码，用于将参数传递给powershell脚本，并尝试调用管道来获取返回代码。

Hi All,

I have created some C# code that passes parameters to a powershell script and trys to invoke the pipeline to get the return code.

//Create space for the session to run.
            Runspace runspace = RunspaceFactory.CreateRunspace();
            runspace.Open();
            RunspaceInvoke runspaceInvoker = new RunspaceInvoke(runspace);

            //Create a pipeline to send variables 
            Pipeline pipeline = runspace.CreatePipeline();

            //Insert a value into exiting variables in script:
            Command myCommand = new Command(psScriptPath, false);
            CommandParameter param = new CommandParameter
            ("ComputerName", "TestingComputerName");
            CommandParameter param3 = new CommandParameter 
            ("MacAddress", "TestingMacAddress");
            CommandParameter param1 = new CommandParameter
            ("CollectionName", "TestingColelctionName");
            CommandParameter param2 = new CommandParameter
            ("SiteCode", "TestingSiteCode");
            myCommand.Parameters.Add(param);
            myCommand.Parameters.Add(param1);
            myCommand.Parameters.Add(param2);
            myCommand.Parameters.Add(param3);
            pipeline.Commands.Add(myCommand);

            //Return the output from the script
            //int i = pipeline.Invoke().Count;
            Collection<PSObject> returnObjects = pipeline.Invoke();
            
            runspace.Close();

我可以将参数传递给它，但是Collection< psobject> ; returnObjects = pipeline.Invoke（）;这是问题所在。我收到错误消息：

I can pass parameters to it fine but the "Collection<psobject> returnObjects = pipeline.Invoke();" is the problem here. I get the error message :

The term 'Get-CMDevice' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

这是因为在System.Management.Automation.CommandNotFoundException中，它无法识别powershell脚本中使用的此特定cmdlet。我在网上看到它可能是由于C＃exe指向哪个平台但是我已经尝试了x86和x64都没有占上风。



我的powershell脚本为如下：

This is because of the System.Management.Automation.CommandNotFoundException, it does not recognise this particular cmdlet used in the powershell script. I have read online that it can be due to which platform the C# exe is pointed at but i have tried both x86 and x64 to no prevail.

My powershell script as as follows:

Import-Module 'C:\Program Files\Microsoft Configuration Manager\AdminConsole\bin\ConfigurationManager.psd1' -force

$ComputerName = $args[0]
$MacAddress = $args[1]
$CollectionName =  $args[2]
$SiteCode = $args[3]
$SiteDir = $SiteCode + ':'
cd $SiteDir
#If the computer dosent exist add it
$Device = Get-CMDevice -Name $ComputerName
if ($Device -eq $null) {
    Import-CMComputerInformation -CollectionName $CollectionName -ComputerName $ComputerName -MacAddress $MacAddress
    return 1
} else {
    #Pop it in the collection
    Add-CMDeviceCollectionDirectMembershipRule -CollectionName $CollectionName -Resourceid $device.ResourceID
    return 2
}

是否有其他原因导致此错误？

有没有办法忽略这个错误并继续收集其余的值？

还有另一种方法可以返回实际的返回值并在c＃中捕获它as .Invoke（）做的工作比需要多吗？



非常感谢 - 我期待听到您的回复!!

Is there somehting else causing this error?
Is there a way to ignore this error and carry on collecting the rest of the values?
Is there another way to return the actual return value and capture it within the c# as .Invoke() is doing more work than needed?

Thank you very much - i look forward to hearing your replies!!

推荐答案

ComputerName =

ComputerName =

args [ 0 ]

MacAddress =

MacAddress =
