Powershell 方法调用失败，因为[Microsoft.Exchange.Data.Directory.ADObjectId]不'；t包含名为'的方法；op#U添加'；

我以前从未在PowerShell中遇到过此错误。使用IDE它可以工作，但在ExchangeShell窗口中不工作

我可以在C#中整天这样做，但由于某些原因，它在Powershell中不起作用。我在网上看到过很多例子，说我不能在

.Add（）

方法中使用

+

，也不能将

$results

定义为一个数组，并使用

+=

进行处理，但这些都不起作用

我希望有人能修改我的代码，但也能告诉我为什么这不起作用，这样我就不会再犯这个错误了

错误消息是

Method invocation failed because [Microsoft.Exchange.Data.Directory.ADObjectId] doesn't contain a method named 'op_Addition'. At C:\Users\XXXX\Desktop\bleh1.ps1:168 char:3 + $results.Add($serverName + "|" + $totalDbs.ToString() + "|" + $activeDbs.ToSt ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~‌​~~~~~~~~~~~~~~~~~~~~‌​~~~ + CategoryInfo : InvalidOperation: (op_Addition:String) [], RuntimeException + FullyQualifiedErrorId : MethodNotFound

这就是最终的效果，谢谢@MacroPower的帮助。你删除了你的帖子，所以我不知道如何给你的回答信用

您是对的，因为$server变量没有显式地作为字符串类型，所以需要.ToString（）强制转换
