问题描述
我正在使用 System.Management.Automation 在 VB 中运行一个简单的脚本,如下所示
I am running a simple script in VB using System.Management.Automation as below
脚本运行良好,但我如何在它运行后访问代码中 $offline 和 $online 的内容?
Script runs fine, but how do I then access content of $offline and $online in my code after it has run?
Dim scriptContents = New StringBuilder()
scriptContents.AppendLine("$computers = @(""PC-1"", ""PC-2"", ""PC-3"")")
scriptContents.AppendLine("$online = @()")
scriptContents.AppendLine("$offline = @()")
scriptContents.AppendLine("Foreach ($computer in $computers) {")
scriptContents.AppendLine("If (Test-Connection -ComputerName $computer -Count 2 -Quiet -ErrorAction SilentlyContinue) {")
scriptContents.AppendLine("$online += $computer")
scriptContents.AppendLine("}")
scriptContents.AppendLine("Else {")
scriptContents.AppendLine("$offline += $computer")
scriptContents.AppendLine("}")
scriptContents.AppendLine("}")
Using ps As PowerShell = PowerShell.Create()
ps.AddScript(scriptContents.ToString)
Dim results1 As PSDataCollection(Of PSObject) = Await Task.Run(Function() ps.InvokeAsync)
Stop
End Using
谢谢
推荐答案
我认为解决方案是不让脚本创建两个单独的数组,而是让它返回一个 PSObjects 数组,其中每个项目都有两个属性:计算机
和布尔Online
.
I think the solution is to not have the script create two separate arrays, but instead have it return one array of PSObjects where each item has two properties: Computer
and a Boolean Online
.
大概是这样的:
Dim scriptContents = New StringBuilder()
scriptContents.AppendLine("$computers = @(""PC-1"", ""PC-2"", ""PC-2"")")
scriptContents.AppendLine("Foreach ($computer in $computers) {")
scriptContents.AppendLine("If (Test-Connection -ComputerName $computer -Count 2 -Quiet -ErrorAction SilentlyContinue) {")
scriptContents.AppendLine(" [PsCustomObject]@{Computer = $computer; Online = $true}")
scriptContents.AppendLine("}")
scriptContents.AppendLine("Else {")
scriptContents.AppendLine(" [PsCustomObject]@{Computer = $computer; Online = $false}")
scriptContents.AppendLine("}")
scriptContents.AppendLine("}")
Using ps As PowerShell = PowerShell.Create()
ps.AddScript(scriptContents.ToString)
Dim results1 As Collection(Of PSObject) = ps.Invoke()
End Using
