Powershell - Hash Table Escape Quotes

Question

我想檢索與哈希表TEST中的特定項相關聯的值，但它不起作用。 你可以幫幫我嗎？

$TEST= 
@{"Monday" = "A"; "Tuesday" = "B"; "Wednesday" = "C"; "Thursday" = "D"; "Friday" = "F"}

$Date = Get-Date
$a = $TEST.Get_Item($Date.get_DayOfWeek())

Write-Host $a

也嘗試：

$TEST= 
@{"Monday" = "A"; "Tuesday" = "B"; "Wednesday" = "C"; "Thursday" = "D"; "Friday" = "F"}

$Date = Get-Date
$a = $Date.get_DayOfWeek()
$b = TEST.Get_Item($a)

和：

$TEST= 
@{Monday = "A"; Tuesday = "B"; Wednesday = "C"; Thursday = "D"; Friday = "F"}

$Date = Get-Date
$a = $TEST.Get_Item($Date.get_DayOfWeek())

Write-Host $a

非常感謝！

Answer 1

DayOfWeek是一個對象而不是字符串，試試這個：

$TEST[(Get-Date).DayOfWeek.ToString()]

Answer 2

問題是你沒有將字符串傳遞給你的哈希表嘗試這樣的事情：

$TEST= 
@{"Monday" = "A"; "Tuesday" = "B"; "Wednesday" = "C"; "Thursday" = "D"; "Friday" = "F"}

$Date = Get-Date
$a = $TEST[""+$Date.get_DayOfWeek()]

Write-Host $a
