未指定數據類型時,PowerShell 會將每個數位建立為物件陣列(System.Object[])。 若要判斷陣列的數據類型,請使用 GetType() 方法。 例如:PowerShell 複製 $A.GetType() 若要建立強型別陣列,也就是只能包含特定型別值的陣列,請將變數轉換成數位類型,例如 string[]、 long[]或int32[]。 若要轉換陣列,請...
在PowerShell 中,scriptblock 對應至 System.Management.Automation.ScriptBlock。 Invoke 會傳回 PSObject的集合。4.3.8 數學類型類型math 提供某些常數和方法的存取權,這些常數和方法在數學計算中很有用。 它有下列可存取的成員:展開資料表 成員 成員種類 類型 用途 E 靜態屬性 (只讀) 雙 自然對數基底 圓周率 ...

要做到这点,在管道中使用Where-Object来处理Dir返回的结果,然后再使用ForEach-Object,或者你自定义的管道过滤。 你还可以将多个Dir 命令执行的结果结合起来。在下面的例子中,两个分开的Dir命令,产生两个分开的文件列表。然后PowerShell将它们结合起来发送给管道进行深度处理。这个例子获取Windows目录和安装程序目录下的所...

object property values. If sort properties aren't included in a command, PowerShell uses default sort properties of the first input object. If the input object's type has no default sort properties, PowerShell attempts to compare the objects themselves. For more information, see theNotessection...

My favorite solution to the “collection was of a fixed size” problem is to create anArrayList(System.Collections.ArrayList), instead of the default object array (System.Object[]). ArrayLists behave like arrays, but unlike arrays, ArrayList objects don’t have a fixed size. ...
