Powershell v1：是否可以将switch语句的结果赋给变量？

Question

Is it possible to assign the result of a switch statement to a variable.

For example, instead of:

switch ($Extension) 
    { 
        doc {$Location = "C:\Users\username\Documents\"; break} 
        exe {$Location = "C:\Users\username\Downloads\"; break}
        default {$Location = "C:\Users\username\Desktop\"}
    }

Is it possible to do something similar to:

$Location = 
{
    switch ($Extension) 
    { 
        doc {"C:\Users\username\Documents\"; break} 
        exe {"C:\Users\username\Downloads\"; break}
        default {"C:\Users\username\Desktop\"}
    }
}

Trying the above results in $location containing the entire code block as a String.

Answer 1

For V1, I would wrap the switch statement in a function.

function Get-DocumentLocation($Extension)
{
    switch ($Extension) 
    { 
        doc {"C:\Users\username\Documents\"; break} 
        exe {"C:\Users\username\Downloads\"; break}
        default {"C:\Users\username\Desktop\"}
    }
}

$Location = Get-DocumentLocation $extension

Answer 2

Does the following work?

$Location = (switch ($Extension) {
               doc {"C:\Users\username\Documents\"; break}
               exe {"C:\Users\username\Downloads\"; break}
               default {"C:\Users\username\Desktop\"}
             })

Or maybe

$Location = $(switch ($Extension) {
               doc {"C:\Users\username\Documents\"; break}
               exe {"C:\Users\username\Downloads\"; break}
               default {"C:\Users\username\Desktop\"}
             })

Don't have v1 here to test, right now but I think that might work.
