Powershell 匹配system.string值

我正在使用Powershell调用命令并将结果作为system.string获取，我需要匹配结果的一部分作为检查点以继续使用脚本

例如，我将结果添加到一个名为$upgradecomm的变量中，如果我尝试打印它，我得到的结果如下：

C:\> $upgradecomm


Host       : HQ-ESXi-Edge-01a.nsx.gss
Output     : {Update Result,    Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.,    Reboot Required: true,    VIBs 
             Installed: VMware_bootbank.........

“上面的输出仍然有更多，但我不会将它们添加到此帖子中。”

我需要的是匹配消息部分中显示的部分（更新成功完成，但需要重新启动系统才能使更改生效）

如果我只打印输出，我将得到以下结果：

C:\> $upgradecomm.Output
Update Result
   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
   Reboot Required: true
   VIBs Installed: VMware_bootbank.....................

“上面的输出仍然有更多，但我不会将它们添加到此帖子中。”

我无法在这里获得我需要的内容，因为我说过我需要检查是否从结果中获得以下内容（更新成功完成，但需要重新启动系统才能使更改生效）。这样我就可以继续我的脚本，如果没有获得，我将打印错误

任何想法都将受到欢迎。

如果你不在乎正文的其余部分说了什么，像这样简单的

，就足够了

$success = "*The update completed successfully, but the system needs to be rebooted for the changes to be effective.*"
if($upgradecomm.Output -like $success){
#success
}

输出
-属性是字符串数组。您可以使用ex.
-match
在数组中搜索与关键字匹配的字符串。如果它返回任何值，那就是匹配

#Creating sampleobject
$o = "Update Result",
"   Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.",
"   Reboot Required: true",
"   VIBs Installed: VMware_bootbank....................."

$upgradecomm = New-Object psobject -Property @{
    Host = "Server1"
    Output = $o
}

#Verify that sampleobject is correct
$upgradecomm | Format-List *
#Output

Host   : Server1
Output : {Update Result,    Message: The update completed successfully, but the system needs to be rebooted for the changes to be effe
         ctive.,    Reboot Required: true,    VIBs Installed: VMware_bootbank.....................}

#Check if successfull and rebooted are in the message-string in output
if($upgradecomm.Output -match 'Message: .*?successfull.*?rebooted') { "Do something" }
#Output
Do something

.Output-如“*成功完成，但系统需要重新启动*”
？
