爲什麼我的「If Else」語句被跳過？

Question

我正在使用腳本來允許我的系統管理員對ACL進行更改，而不必深入到文件夾級別。到目前爲止，除了我的第一個開關中的第一個「If..Else」語句，一切都按預期執行。它完全被跳過，並繼續詢問帳戶名稱，我無法弄清楚原因。

有沒有人有什麼想法？

您的if-else正如您所寫的那樣正常工作。然而，你寫的東西並不是你想要的。

第一條：在Write-Host中的else條款中，您不希望使用轉義的`r;你想使用一個轉義的`n，或者什麼也沒有。 `r表示返回行開始但不轉到下一行; `n表示返回到行開始行並轉到下一行。在上面的示例中，以綠色重複輸入的路徑暗示Write-Host正在執行。

其次，您的Test-Path導致$test沒有任何價值，因爲您將結果發送給空設備，而不是將其返回給語句以分配給變量。刪除| Out-Null。
