powershell - 可以使用Get-Member检查集合的方法和属性，而不是检查集合项(默认值)吗？

Question

假设$coll是对象的集合。 $coll | Get-Member显示集合项的成员。我不知道它是如何工作的，无论它是检查第一个项目然后停止还是显示所有项目成员的并集。但是，它会检查项目，而不是收集对象本身。通常，这就是我们想要的。

但是，如果我想检查馆藏本身怎么办？我仍然可以这样做还是必须使用.NET反射功能？

Answer 1

愚蠢的我，当然可以。我只需要使用-InputObject参数，而不是管道-Get-Member -InputObject $coll而不是$coll | Get-Member
