各位大神好，本人小白，刚接触powershell不久，最近遇到start-job无法获得运行结果的问题迷茫不已，麻烦各位大神帮忙解答，谢谢~~
版本信息： $PSVersionTable
Name Value
—- —–
PSVersion 5.1.14409.1005
PSEdition Desktop
PSCompatibleVersions {1.0, 2.0, 3.0, 4.0…}
BuildVersion 10.0.14409.1005
CLRVersion 4.0.30319.42000
WSManStackVersion 3.0
PSRemotingProtocolVersion 2.3
SerializationVersion 1.1.0.1
脚本内容：

start-job -name job1 -ScriptBlock {if (Test-Connection -ComputerName http://www.baidu.com -Quiet){ echo “Website is ok”;echo “Website is ok”>>.\record.txt} else {echo “Website is down”;echo “Website is down” >>.\record.txt}}

 
单独使用if判断可以正确显示和记录结果，但放到start-job里就无法获得和记录结果.实在不晓得哪里犯了错.麻烦各位大神指教~
