从.NET调用父ps1时，如何执行子ps1

Question

我有一个ASP.NET应用程序，我希望调用一个Powershell脚本来获得结果。我已经做了一些挖掘，发现了很多关于PS1/2的过时信息，但没有关于PS4以上版本的信息。

我有一个PowerShell脚本，它现在可以完成一些操作，并将ArrayList输出到PowerShell控制台。Powershell脚本调用另一个PowerShell脚本：

.\Get-AzureSubscription.ps1

$environments = New-Object System.Collections.ArrayList
$resourceGroups = Get-AzureRMResourceGroup

foreach($thisResourceGroup in $resourceGroups)
{
    $resourceGroupVMs = Get-AzureRmVM -ResourceGroupName $thisResourceGroup.ResourceGroupName

    $environment = New-Object -TypeName PSObject
    $environment | Add-Member -MemberType NoteProperty -Name ResourceGroupName -Value $thisResourceGroup.ResourceGroupName
    $environment | Add-Member -MemberType NoteProperty -Name Id -Value $thisResourceGroup.ResourceId

    $machines = New-Object System.Collections.ArrayList

    foreach($thisMachine in $resourceGroupVMs)
    {
        $machine = New-Object -TypeName PSObject
        $machine | Add-Member -MemberType NoteProperty -name Name -value $thisMachine.Name
        $machine | Add-Member -MemberType NoteProperty -name ResourceGroupName -value $thisResourceGroup.ResourceGroupName 

        $status = Get-AzureRmVM -ResourceGroupName $thisResourceGroup.ResourceGroupName -Name $thisMachine.Name -Status | `
                         Select-Object -ExpandProperty Statuses | `
                         Where-Object { $_.Code.StartsWith("PowerState") } | `
                         Select-Object -ExpandProperty Code

        $regex = [Regex] '\/(.*?)$'
        $machine | Add-Member -MemberType NoteProperty -name Status -value $regex.Match($status).Groups[1].Value


        $machines.Add($machine) > $null;
    }

    $environmentStatuses = $machines | Select-Object ResourceGroupName -ExpandProperty Status | Group-Object ResourceGroupName, Status

    $environment | Add-Member -MemberType NoteProperty -name Statuses -value $environmentStatuses
    $environments.Add($environment) > $null;
}

$environments

我还有以下.NET代码，它试图通过将PS1脚本的内容作为字符串传入来执行外部脚本：

public Collection<PSObject> RunScript(string script, Dictionary<string, string> parameters = null)
{
    // Validate parameters
    if (string.IsNullOrEmpty(script)) { throw new ArgumentNullException(nameof(script)); }
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

    using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration))
    {
        runspace.Open();

        using (RunspaceInvoke invoker = new RunspaceInvoke(runspace))
        {
            invoker.Invoke("Set-ExecutionPolicy Unrestricted");

            Pipeline pipeline = runspace.CreatePipeline();

            Command scriptCommand = new Command(script, true);
            parameters?.Select(kvp => new CommandParameter(kvp.Key, kvp.Value))
                .ForEach(scriptCommand.Parameters.Add);

            pipeline.Commands.Add(scriptCommand);

            var result = pipeline.Invoke();

            return result;
        }
    }
}

问题是，如果我从.NET调用ps1，它会失败，并抱怨The term '.\Get-AzureSubscription.ps1' 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.如果我从PowerShell执行ps1，它会执行而不会出现问题。

如果我将Get-AzureSubscription.ps1的内容复制并粘贴到由.NET直接调用的ps1中，而不是链接这两个脚本，则所有内容都会成功地传递回.NET。

Answer 1

不能保证.NET应用程序的工作目录与您从其中调用的脚本相同。

您可以使用此技巧找出调用脚本的完整路径(将第一行替换为以下代码)：

$AzureSubscriptionScript = Join-Path $PSScriptRoot "Get-AzureAssistantSubscription.ps1"
& $AzureSubscriptionScript

$PSScriptRoot是一个自动变量，它将当前/调用脚本在磁盘上的位置的路径作为它的值
