Powershell 中的 XML 解析器并在验证后移动文件

Question

以下脚本已经运行良好。我可以根据

xml

文件验证我给定的

xsd

文件并记录所有验证错误。 我的问题是，如果没有发生验证错误，我想移动

xml

文件。但是我不知道在哪里放置

move-item

声明。我总是得到错误

file can not moved because it is still in use.

这是代码。希望有人能帮忙。

# Get all XML files in the folder that start with "products"

        finally {

            # make sure the xml reader is closed even if an exception occurs
           if ($xmlReader -ne $null) {
                $xmlReader.Dispose()
                $xmlReader.close()
                Move-Item $xmlFile.FullName $destination -Force
            }
        }
    } #End If-else
 } #End ForEach Loop

创建的 xmlReader 在我尝试移动文件之前关闭。但是文件仍然是块，我不知道为什么。
