從函數返回值（從現有變量名稱設置變量）

Question

我想將兩個參數傳遞給我的函數，並根據結果設置變量（和變量名稱）。我一直在試圖做到這一點的方式如下：

$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？

Answer 1

只要確保你的函數打印出來的唯一的價值是結果：

$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，現在提供的是Yes或No，只是把它分配給您的變量
