写入现有xml文件时出错 [英] Error while writing into an existing xml file

问题描述

我正在创建一个应用程序，我正在读取xml，添加一些节点然后保存它。



保存时我收到以下错误。



进程无法访问文件'C：\p401573 \ myxml.xml '因为它正在被另一个进程使用。



我的代码如下

Hi,

I am creating an application where i am reading an xml,Adding some nodes and then saving it.

While saving i am getting following error.

"The process cannot access the file '"C:\p401573\myxml.xml"' because it is being used by another process."

My code is as follows

Dim xmldoc As New XmlDocument
xmldoc.Load("C:\p401573\myxml.xml")
'ConfigurationManager.AppSettings("Path") + "
Dim nlist As XmlNodeList = xmldoc.GetElementsByTagName("UserSettings")
Dim elem As XmlElement = xmldoc.CreateElement("", "User", "")
elem.SetAttribute("group", cbxUserProfile.SelectedItem)
elem.SetAttribute("Rights", "N")
nlist.Item(0).AppendChild(elem)
xmldoc.Save("C:\p401573\myxml.xml")

在最后一行代码中，当我将xml文档保存回上面的文件时出现错误。有时这段代码正在工作
