Powershell v1 : Is it possible to assign the result of a switch statement to a variable?

Question

是否可以将 switch 语句的结果分配给变量。

例如，而不是:

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

是否可以做类似的事情:

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

尝试上述结果会导致 $location 包含整个代码块作为字符串。

Answer 1

对于 V1，我会将 switch 语句包装在一个函数中。

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
