译者注 以上就是说hashtable被视为一个整体对象,因此你使用Measure-Object来获取它的元素个数的时候,你将得不到正确结果.很多初识powershell的童鞋不知道如何获取集合元素的个数,其实一般是通过在管道下一级使用Measure-Object来实现的 measure-object 展示信息中count属性即为集合元素的个数.如果你想要通过程序化的方...
$people|ConvertTo-JSON|Set-Content-Path$path$people=Get-Content-Path$path-Raw|ConvertFrom-JSON 此方法有两个重要方面。 首先,JSON 采用多行编写,因此我需要使用-Raw选项将其读回到单个字符串中。 其次,导入的对象不再是[hashtable]。 它现在是[pscustomobject],如果你不希望是这样,可能会导致问题。

Automatic unraveling can also be confusing in the context of returning an object from a function call. If you would like to return an enumerable object from a function or script, you’ll want to wrap that object in an array using the unary comma operator. ...

Selects objects from indexed collections, such as arrays and hash tables. Array indexes are zero-based, so the first object is indexed as[0]. You can also use negative indexes to get the last values. Hash tables are indexed by key value. ...
