从函数返回值（从现有变量名称设置变量）

Question

我想将两个参数传递给我的函数，并根据结果设置变量（和变量名称）。我一直在试图做到这一点的方式如下：

$service_to_check_for = "ping" 

function check-service-monitored ($check_command,$check_name) { 
    if($service_to_check_for -eq $check_command) 
    { 
     $Value = "Yes" 
    } 
    else 
    { 
     $Value = "No" 
    }  

    $script:check_command = $check_command 
    $script:check_name = $check_name 
    $script:value = $Value 
} 

check-service-monitored "ping" "NagiosPing" 

echo "$check_name : $value" 

我想

 $NagiosPing = "Yes" 

但如何？

只要确保你的函数打印出来的唯一的价值是结果：

$service_to_check_for = "ping" 

function check-service-monitored ($check_command,$check_name) { 
if($service_to_check_for -eq $check_command) 
{ 
    "Yes" 
} 
else 
{ 
    "No" 
}  

$script:check_command = $check_command 
$script:check_name = $check_name 
$script:value = $Value 
} 

$NagiosPing = check-service-monitored "ping" "NagiosPing" 
$NagiosPing 

的功能，现在提供的是Yes或No，只是把它分配给您的变量
