我有一个创建新 AD 对象的脚本（通过 New-ADObject，碰巧）。如果对象已经存在，我需要捕获并处理它。但是，异常类型并不像FullyQualifiedErrorId 那样明确。请注意以下事项：

> $Error[-1] | Format-List -Property * -Force

writeErrorStream      : True
PSMessageDetails      : 
Exception             : Microsoft.ActiveDirectory.Management.ADException: An attempt was made to add an object to the directory with 
                    a name that is already in use ---> System.ServiceModel.FaultException: The supplied entry already exists.

如何在我的 Catch 块中使用更详细的信息？

FullyQualifiedErrorId 只是异常对象的 .Message 属性以及异常产生的类的完全限定名称。

您无法通过FullyQualifiedErrorId 捕获，但您可以通过异常类型捕获：

try {
    # Do something that causes the 'name already in use' exception you're getting.
} catch [System.ActiveDirectory.Management.ADException] {
    if ($_.Exception.Message -ilike "*already in use") {
        # Do something to handle the error condition.
    }
}

请注意，这不是跨不同语言的可移植解决方案，因为异常消息可能在非英语版本的 Windows 上本地化。

此外，您可能必须修改您的 try 块以包含-ErrorAction Stop以确保捕获错误。

如果抛出的错误New-ADObject不是终止错误，则使用 catch 将无济于事。您可以做的一件事是使用 ErrorAction 参数使错误成为终止错误：

try{
   New-ADObject ... -ErrorAction Stop
}
catch{
   ... handle the error ....
}

我不知道您是否可以通过 捕获异常FullyQualifiedErrorId，但我找到了这种方法来获取它并且它对我有用：

$InerrMessage= $_.FullyQualifiedErrorId
