获取无法将参数绑定到参数'Path',因为它在powershell中是null错误

Question

我正在尝试根据文件名将文件名中的特殊字符移到某个目的地后移动所有邮件.FOLDLIST是一个数组,我有条件变量和目标foldername.

    Set-Location 'C:\Users\abrahame\Desktop\Work\PSG Mail Movement\Mail'
    $DESLOC="c:\Temp\ua-closed bugs"
    $FOLDLIST = @(("UA", "CLOSE",  "ua-closed bugs"), ("VS", "CLOSE", "vs-closed-bugs"), ("CM", "CLOSED", "cm - closed-bugs"))
    gci | Foreach-object { $NEWN = $_.Name -replace '&',' ' -replace '_', ' ' -replace '#', ' ' -replace '!', ' '  -replace '@', ' '  -replace '$', ' '  -replace '%', ' '  -replace '^', ' '  -replace '&', ' '  -replace '\(', ' ' -replace '\)', ' '  -replace '\[', ' ' -replace '\]', ' ' -replace '\{', ' '  -replace '\}', ' ' -replace '\-', ' ';
            write-host $NEWN.Length
            if($NEWN.Length -gt  70){
                    $NEWN="$NEWN.Substring(1,70)"
                    $NEWN=$NEWN.msg


            }

            $FOLDLIST | ForEach-Object {
            $CXR=$_[0]
            $STAT=$_[1]

            if ($NEWN -match ("$CXR") -and $NEWN -match ("$STAT")){
            write-host $CXR -  $STAT
                    $DIR=$_[2]
                    $NEWN=$NEWN.trim()
                    $DPATH="$DESLOC\$DIR\$NEWN"
                    write-host $DPATH
                    mv $_.Name $DPATH
            }
            }

    }

我收到了这个错误.请告知我错误的地方..

我的猜测是$ _。Name不存在。

如果我是您，则将脚本带到ISE中并逐行运行，直到到达为止，然后查看$ _的值
