为什么我在运行这两个简单样本时会在控制台上显示错误消息？我希望我得到"错误测试:)"打印在控制台上:

Get-WmiObject:RPC服务器不可用.(来自HRESULT的异常:0x800706BA)在行:3 char:15 + Get-WmiObject <<<< --ComputerName possible.nonexisting.domain.com -Credential(Get-Credential)-Class Win32_logicaldisk + CategoryInfo:InvalidOperation:(:) [ Get-WmiObject],COMException + FullyQualifiedErrorId:GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

要么

试图除以零.在行:3 char:13 + $ i = 1/<<<< 0
+ CategoryInfo:NotSpecified:(:) [],ParentContainsErrorRecordException + FullyQualifiedErrorId:RuntimeException

第一个例子:

try
{
    $i = 1/0   
    Write-Host $i     
}
catch [Exception]
{ 
    Write-Host "Error testing :)" 
}

第二个例子:

try
{
    Get-WmiObject -ComputerName possibly.nonexisting.domain.com -Credential (Get-Credential) -Class Win32_logicaldisk 
}
catch [Exception]
{ 
    Write-Host "Error testing :)" 
}

非常感谢你!
