powershell - X509Store.Open()引发异常

Question

为什么$store.Open($openFlags)会引发异常，并且有比我的“变通方法”更好的方法来使其工作吗？

<#
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store("Cert:\CurrentUser\My")
$openFlags = [System.Security.Cryptography.X509Certificates.OpenFlags]::MaxAllowed

$store.Open($openFlags) #Exception calling "Open" with "1" argument(s): "The parameter is incorrect.
#>

#Work Around:
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store("Cert:\CurrentUser\My")
$openFlags = [System.Security.Cryptography.X509Certificates.OpenFlags]::MaxAllowed

$startIndexOfStoreName = $store.Name.LastIndexOf("\") + 1
$lengthOfStoreName = $store.Name.Length - $startIndexOfStoreName
$storeNameString = $store.Name.Substring($startIndexOfStoreName, $lengthOfStoreName)
$storeName = [System.Security.Cryptography.X509Certificates.StoreName]$storeNameString
$store = New-Object System.Security.Cryptography.X509Certificates.X509Store($storeName, $store.Location)

$store.Open($openFlags) #No Exception thrown!

更新:似乎在使用X509Store(String)构造函数时，不允许使用任何斜杠(如果我错了，请纠正我)。因此$store = New-Object System.Security.Cryptography.X509Certificates.X509Store("My")起作用。

Answer 1

使用以下方法定义证书存储

$store = Get-Item "Cert:\CurrentUser\My"

代替

$store = New-Object System.Security.Cryptography.X509Certificates.X509Store("Cert:\CurrentUser\My")

老实说，我仍在努力弄清楚它为什么起作用，或如何起作用。

第一种方法返回一个名为“My”的$ store，因此我假设它专门针对该商店，您可以使用

$store.Open($openFlags)

第二种方法返回一个名为“Cert:\ CurrentUser \ My”的$ store。对此的打开方法将失败。
