powershell - Powershell - 哈希表转义引号

Question

我想检索与哈希表 TEST 中的特定项目关联的值，但它不起作用。你可以帮帮我吗？

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

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

Write-Host $a

也试试：

$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

非常感谢！

Answer 1

DayOfWeek 是一个对象而不是字符串，试试这个：

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

Answer 2

问题是您没有将字符串传递给哈希表，请尝试以下操作：

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

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

Write-Host $a
