Powershell二维阵列未按预期工作

目前,我正在从XML文件加载一些数据,以配置脚本运行的一些参数,但是 $keywords 和 $maxCounts 发送到 CheckForKeywords 作用

function Main()
{

#### VARIABLES RELATING TO THE LOG FILE

#contains the log path and log file mask
$logPaths = @()
$logFileMasks = @()

# key value pair for the strings to match and the max count of matches before they are considered an issue
$keywords = @(,@())
$maxCounts = @(,@())


#### FUNCTION CALLS

LoadLogTailerConfig $logConfigPath ([ref]$logPaths) ([ref]$logFileMasks) ([ref]$keywords) ([ref]$maxCounts)

for ($i = 0; $i -lt $logPaths.Count; $i++)
{
    $tail = GetLogTail $numLinesToTail $logPaths[$i] $logFileMasks[$i]

    $tailIssueTable = CheckForKeywords $tail $keywords[$i] $maxCounts[$i]


}

}

# Loads in configuration data for the utility to use
function LoadLogTailerConfig($logConfigPath, [ref]$logPaths, [ref]$logFileMasks, [ref]$keywords, [ref]$maxCounts)
{
    Write-Debug "Loading config file data from $logConfigPath"

    [xml]$configData = Get-Content "C:\Testing\Configuration\config.xml"

    foreach ($log in $configData.Logs.Log) {

        $logPaths.Value += $log.FilePath
        $logFileMasks.Value += $log.FileMask

        $kwp = @()
        $kwc = @()

        foreach ($keywordSet in $log.Keywords.Keyword)
        {
            $kwp += $keywordSet.Pattern
            $kwc += $keywordSet.MaxMatches 
        }

        $keywords.Value += $kwp
        $maxCounts.Value += $kwc
    }
}

# Returns body text for email containing details on keywords in the log file and their frequency
function CheckForKeywords($tail, $keywords, $maxCounts)
{   
    $issuesFound = 0


    for ($i = 0; $i -lt $keywords.Count; $i++)
    {
        $keywordCount = ($tail | Select-String $keywords[$i] -AllMatches).Matches.Count

        Write-Debug $keywords.Count

        Write-Debug (("Match count for {0} : {1}" -f $keywords[$i], $keywordCount))

        if ($keywordCount -gt $maxCounts)
        {
            #do stuff
        }
    }

    return ""
}
