如何在PowerShell中处理System.Xml.XmlWriter

处置是 protected 在…上 System.Xml.XmlWriter . 你应该使用 Close

$writer.Close

以下是另一种方法:

(get-interface $obj ([IDisposable])).Dispose()

获取接口脚本可以在这里找到 http://www.nivot.org/2009/03/28/PowerShell20CTP3ModulesInPracticeClosures.aspx 并在这篇文章中提出了建议 response

使用“using”关键字,我们得到:

$MY_DIR = Split-Path -Path $MyInvocation.MyCommand.Definition -Parent

# http://www.nivot.org/2009/03/28/PowerShell20CTP3ModulesInPracticeClosures.aspx
. ($MY_DIR + '\get-interface.ps1')

# A bit modified code from http://blogs.msdn.com/powershell/archive/2009/03/12/reserving-keywords.aspx
function using
{
    param($obj, [scriptblock]$sb)

    try {
        & $sb
    } finally {
        if ($obj -is [IDisposable]) {
            (get-interface $obj ([IDisposable])).Dispose()
        }
    }
}

# Demo
using($writer = [System.Xml.XmlWriter]::Create('c:\some.xml')) {

}
