得到錯誤而if語句Powershell的

Question

function IsValidMacAddress($checkvariable) 
{ 
    Write-Output "checking mac" 
    if(($checkvariable -match '^[0-9a-fA-F]+$') -and ($checkvariable.length -eq 12)) 
    { 
    Write-Output "valid mac" 
    return 1 
    } 
    else 
    { 
    Write-Output "not found" 
    return 0 
    } 
} 

這總是返回找不到

Answer 1

只是略有不同的測試兩個條件，但這

function IsValidMacAddress ([string]$checkvariable) { 
    $checkvariable = $checkvariable -replace '-|:' 
    Write-Host "checking mac $checkvariable" 
    if ($checkvariable -match '^[0-9a-f]{12}$') { 
     Write-Host "$checkvariable is valid mac" 
     return 1 
    } else { 
     Write-Host "$checkvariable is not valid mac" 
     return 0 
    } 
}
