已在反覆管線的內容中新增PipelineVariable通用參數的支援,例如 System Center Orchestrator 所使用的參數;也就是說,執行命令的管線只是由左至右,而不是使用串流執行交錯。 已經大幅增強參數繫結在 Tab 鍵自動完成案例之外的運作效能,例如使用目前 Runspace 中不存在的命令。
Object-oriented languages add the idea of inheritance, which allows the runtime type of a variable to be that with which it was declared at compile time or some type derived from that type. Being a dynamically typed language, PowerShell's variables do not have types, per se. In fact, ...

變數是預留給程式存放資料的記憶體空間,現代的高階程式語言都能自行處理記憶體空間配置的細節,不需開發者介入,開發者只需要瞭解 Windows PowerShell 變數的特性,即可直接使用變數(雖然 Windows PowerShell 提供了 New-Variable cmdlet 來宣告並指定變數初值,但未事先宣告亦可使用變數)。 說明變數之前,還記得我們在上一...
Many of the string variable's capabilities are more useful in an administrative context than the string functions in a language like VBScript. Suppose you've written a script that reads in Universal Naming Convention (UNC) paths from a file and does something with them. You'd want to verify...
