breakPowerShell中应该有一个命令，可以通过分配标签退出嵌套循环。只是它不起作用。这是我的代码：
$timestampServers = @(
"http://timestamp.verisign.com/scripts/timstamp.dll",
"http://timestamp.comodoca.com/authenticode",
"http://timestamp.globalsign.com/scripts/timstamp.dll",
"http://www.startssl.com/timestamp"
)
:outer for ($retry = 2; $retry -gt 0; $retry--)
{
Write-Host retry $retry
foreach ($timestampServer in $timestampServers)
{
Write-Host timestampServer $timestampServer
& $signtoolBin sign /f $keyFile /p "$password" /t $timestampServer $file
if ($?)
{
Write-Host OK
break :outer
}
}
}
if ($retry -eq 0)
{
WaitError "Digitally signing failed"
exit 1
}
它打印以下内容：
retry 2
timestampServer http://timestamp.verisign.com/scripts/timstamp.dll
Done Adding Additional Store
Successfully signed and timestamped: C:\myfile.dll
OK
retry 1
timestampServer http://timestamp.verisign.com/scripts/timstamp.dll
Done Adding Additional Store
Successfully signed and timestamped: C:\myfile.dll
OK
ERROR: Digitally signing failed
我做错了什么？
请给我goto和标签吗？
使用Windows 7，我猜是PS 2.0。该脚本至少应在PS 2上运行。
break与循环标签一起使用时，请勿添加冒号。这行：
break :outer
应该这样写：
break outer
为了进一步演示，请考虑以下简单脚本：
:loop while ($true)
{
while ($true)
{
break :loop
}
}
执行后，它将永久运行而不会中断。但是此脚本：
:loop while ($true)
{
while ($true)
{
break loop
}
}
退出，因为我更改break :loop为break loop。
