? 拷贝后，怎么判断最新文件

新增的速度，最小间隔是多少？
试试4楼的

newswan

$pathSour = "D:\1\"
$pathDest = "D:\2\"
$timeInter = 1

$filexmlLast = ""

while ($True) {
	$filexml = Get-ChildItem -Path $pathSour -Filter "*603.xml" | Sort-Object LastWriteTime | Select-Object -Last 1
	$filexml = $filexml.FullName
	if ( $filexmlLast -ne $filexml ) {
		$filexmlLast = $filexml
		[xml]$xml = Get-Content -Path $filexml -Encoding "UTF8"
		$xml.datas.data.attribute | ForEach-Object {
			if ( $_.name -eq "msg" ) { $string = $_.value }
		}
		if ( $string -match '"CardLocalFee":"0","CardLocalPayfee":"0"' ) {
				$path = $pathDest + (Get-Date).ToString("yyyy-MM-dd") + "\"
				if ( -not ( Test-Path $path ) ) { New-Item -Type Directory -Path $path }
				Write-Host "Copy :  $filexml"
				Copy-Item -Path $filexml -Destination $path
		}
	}
	Start-Sleep -Seconds $timeInter
}
复制代码

1秒左右？如果生成时间间隔小于 $timeInter，会拷贝不全
时间间隔过小，会不会浪费性能？
