powershell - 在Powershell中获取ExecutionPolicy的成员

Question

我正在尝试编写一个可扩展的实用程序，而不是对各种类型的执行策略进行硬编码。使用Get-Command可以获取有关Set-ExecutionPolicy的一些信息，但无法获取参数类型Microsoft.Powershell.ExecutionPolicy的成员。

(get-command set-executionpolicy).parameters.executionpolicy

就我所知。我试过使用get-typedata，但是将Microsoft.Powershell.ExecutionPolicy传递给它时，它什么也不返回。

因此问题是:如何枚举所有执行策略类型？

Answer 1

您有两种选择:

＃1-与枚举对象属性进行交互:

[Microsoft.PowerShell.ExecutionPolicy] | Get-Member -Static -MemberType Property

   TypeName: Microsoft.PowerShell.ExecutionPolicy

Name         MemberType Definition
----         ---------- ----------
AllSigned    Property   static Microsoft.PowerShell.ExecutionPolicy AllSigned {get;}
Bypass       Property   static Microsoft.PowerShell.ExecutionPolicy Bypass {get;}
Default      Property   static Microsoft.PowerShell.ExecutionPolicy Default {get;}
RemoteSigned Property   static Microsoft.PowerShell.ExecutionPolicy RemoteSigned {get;}
Restricted   Property   static Microsoft.PowerShell.ExecutionPolicy Restricted {get;}
Undefined    Property   static Microsoft.PowerShell.ExecutionPolicy Undefined {get;}
Unrestricted Property   static Microsoft.PowerShell.ExecutionPolicy Unrestricted {get;}

＃2在v3中引入，与枚举本身进行交互(这是@PetSerAl注释的简短版本):

                                            # Values()
[Microsoft.PowerShell.ExecutionPolicy].GetEnumNames()

Unrestricted
RemoteSigned
AllSigned
Restricted
Restricted
Bypass
Undefined

v3之前的版本:

         # Names()
[Enum]::GetValues('Microsoft.PowerShell.ExecutionPolicy')
