Passing enum values to a function in PowerShell

Question

I have a function accepting an enum value as parameter. As an example, consider something like:

(PS) > function IsItFriday([System.DayOfWeek] $dayOfWeek) { 
          


        

Answer 1

Even handier is that strings will get converted to enum values if valid:

function IsItFriday([System.DayOfWeek] $dayOfWeek) {   
    if($dayOfWeek -eq [System.DayOfWeek]::Friday) {  
        "yes"  
    } else {  
        "no"  
    }   
}

PS 7> IsItFriday Monday
no
PS 8> IsItFriday Friday
yes
