Powershell - Hash Table Escape Quotes

Question

I would like to retrieve a value associated with a specific item in the hash table TEST but its not working. Could you help me?

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

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

Write-Host $a

also try:

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

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

and:

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

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

Write-Host $a

Thanks a lot!

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

The problem is that you not passing a string to your hash table try something like this:

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

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

Write-Host $a
