我试图解决我的照片使用PowerShell的元数据。我需要设置EXIF DateTaken如文件创建时间
这里是我的代码：
[reflection.assembly]::loadfile( "C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll")
echo "--------"
echo ""
$files = Get-ChildItem E:\Photos\*.*
ForEach ($file in $files) {
#Get Date
$foo=New-Object -TypeName system.drawing.bitmap -ArgumentList $file.fullname
$date = $foo.GetPropertyItem(36867).value[0..9]
$arYear = [Char]$date[0],[Char]$date[1],[Char]$date[2],[Char]$date[3]
$arMonth = [Char]$date[5],[Char]$date[6]
$arDay = [Char]$date[8],[Char]$date[9]
$strYear = [String]::Join('',$arYear)
$strMonth = [String]::Join('',$arMonth)
$strDay = [String]::Join('',$arDay)
$DateTaken = $strDay + "/" + $strMonth + "/" + $strYear
# Get Time
$time = $foo.GetPropertyItem(36867).value[11..18]
$arHour = [Char]$time[0],[Char]$time[1]
$arMinute = [Char]$time[3],[Char]$time[4]
$arSecond = [Char]$time[6],[Char]$time[7]
$strHour = [String]::Join('',$arHour)
$strMinute = [String]::Join('',$arMinute)
$strSecond = [String]::Join('',$arSecond)
$TimeTaken = $strHour + ":" + $strMinute + ":" + $strSecond
# Link into one date and time
$FullDate = $DateTaken + " " + $TimeTaken
echo "File name"
echo $file.name
echo ""
echo "Wrong data"
echo (Get-Item $file).creationtime.datetime
echo ""
echo "Right data"
echo $FullDate
echo ""
#Set DateTaken as CreationTime
(Get-Item $file).creationtime= $FullDate
pause
}
我得到了错误“因为它正被另一个进程无法访问文件”。我不知道如何解决它。
PS。我不知道如果$FullDate有正确的语法，因为我无法测试
谢谢
你试过获得通过调用$ foo.dispose（）摆脱了$ foo的对象？
由于@TomG，这解决了我的问题，我已经完成了这个项目。我张贴的代码，这可能会帮助一个人在未来的照片固定日期
[reflection.assembly]::loadfile( "C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll")

echo $file.fullname

# Write-Host 'File no: ' $i
# echo ""
#Get Date
$foo=New-Object -TypeName system.drawing.bitmap -ArgumentList $file.fullname
$date = $foo.GetPropertyItem(36867).value[0..9]
$arYear = [Char]$date[0],[Char]$date[1],[Char]$date[2],[Char]$date[3]
$arMonth = [Char]$date[5],[Char]$date[6]
$arDay = [Char]$date[8],[Char]$date[9]
$strYear = [String]::Join('',$arYear)
$strMonth = [String]::Join('',$arMonth)
$strDay = [String]::Join('',$arDay)
# Date to string
# $DateTaken = $strDay + "/" + $strMonth + "/" + $strYear
# Get Time
$time = $foo.GetPropertyItem(36867).value[11..18]
$arHour = [Char]$time[0],[Char]$time[1]
$arMinute = [Char]$time[3],[Char]$time[4]
$arSecond = [Char]$time[6],[Char]$time[7]
$strHour = [String]::Join('',$arHour)
$strMinute = [String]::Join('',$arMinute)
$strSecond = [String]::Join('',$arSecond)
$foo.dispose()
# Time to string
# $TimeTaken = $strHour + ":" + $strMinute + ":" + $strSecond
$NewDate = (Get-Date -Year $strYear -Month $strMonth -Day $strDay -Hour $strHour -Minute $strMinute -Second $strSecond)
#Set DateTaken as CreationTime
(Get-Item $file).CreationTime = $NewDate
(Get-Item $file).LastWriteTime = $NewDate
$i++
# Clear-Host
}
echo ""
echo "Done"
