是否有任何库或项目可以在 Powershell 中实现 PSObject 的原型继承？

我不这么认为，因为您甚至无法让 PSObject 将自身标识为自定义类型，例如：

PS> $obj = new-object psobject
PS> $obj.psobject.TypeNames.Insert(0,'MyCustomType')
PS> $obj.psobject.TypeNames
MyCustomType
System.Management.Automation.PSCustomObject
System.Object
PS> $obj -is [MyCustomType]
Unable to find type [MyCustomType]: make sure that the assembly 
containing this type is loaded.

但是您可以使用 Add-Type -TypeDefinition 来添加基于 C# 的类定义，并完成继承，在你的脚本中。 PowerShell 的本质仍然是一种命令行 shell 和脚本语言。它不具备（也可能不应该具备）通用编程语言（例如 Python）的所有功能。

I don't think so since you can't even get a PSObject to identify itself as a custom type e.g.:

PS> $obj = new-object psobject
PS> $obj.psobject.TypeNames.Insert(0,'MyCustomType')
PS> $obj.psobject.TypeNames
MyCustomType
System.Management.Automation.PSCustomObject
System.Object
PS> $obj -is [MyCustomType]
Unable to find type [MyCustomType]: make sure that the assembly 
containing this type is loaded.

However you can use Add-Type -TypeDefinition to sprinkle C#-based class definitions, complete with inheritance, in your script. The thing with PowerShell it is still primarily a command line shell and scripting language. It doesn't have (and probably shouldn't have) all the features of a general purpose programming language like say Python.
