使用上面的代码将密码存储在文本文件c：\ pass.txt中，而不必多次重新输入密码。

尝试此代码时，我看到以下错误：

PS C：\ temp＆gt; 。\ passcerds.ps1使用存储的凭据文件   ConvertTo-SecureString：无法处理参数因为值   参数“输入”无效。更改“input”参数的值   并再次运行该操作。在C：\ temp \ passcerds.ps1：12 char：64   + $ password = get-content $ CredsFile | convertto-securestring＆lt;＆lt;＆lt;＆lt;       + CategoryInfo：InvalidArgument：（:) [ConvertTo-SecureString]，PSArgumentException       + FullyQualifiedErrorId：ImportSecureString_InvalidArgument，Microsoft.PowerShell.Commands.ConvertToSecureStringC   mmand

脚本开头的单引号是正确还是拼写错误？因为那可能会让事情搞得一团糟......我能够运行下面的代码，它对我有用：

$CredsFile = "C:\pass.txt" 
$FileExists = Test-Path $CredsFile

如果您是从PowerShell运行它而忘记设置$ CredsFile变量，则会出现该错误。对于前者下面会产生同样的错误：

$FileExists = Test-Path $Nothing

用于存储密码的PowerShell脚本失败
