Basic for-loop 範例是效能的基線。 第二個範例會將隨機數產生器包裝在緊密迴圈中呼叫的函式中。 第三個範例會在函式內移動迴圈。 函式只會呼叫一次,但程式代碼仍會產生相同數量的隨機數。 請注意每個範例的執行時間差異。 Output 複製 CollectionSize Test TotalMilliseconds Re
PowerShell 中的循环迭代计数通常是通过 for 循环或 foreach 循环来实现的。下面我将分别介绍这两种循环的基本概念、优势、类型、应用场景以及如何解决可能遇到的问题。 基本概念 for 循环 for 循环是一种预定义迭代次数的循环结构,适用于需要精确控制循环次数的场景。 foreach 循环 foreach 循环用于遍历集合或数组中...
PowerShell evaluates the condition each time the For loop runs. If the statement is $true, the commands in the command block run, and the statement is evaluated again. If the condition is still $true, the commands in the Statement list run again. The loop is repeated until the condition ...
