when save xml error occur as it is being used by another process.

XmlDocument XDOC = new XmlDocument();

XDOC.Load(System.Web.HttpContext.Current.Server.MapPath("~/XmlFiles/Blog.xml"));

XmlNode RootNode = XDOC.SelectSingleNode("//Blogs");

XmlNode childnode = XDOC.SelectSingleNode("/Blogs/IDs");

//check whether childnode exist or not.

if (childnode != null)

childnode.ParentNode.RemoveChild(childnode);

XmlElement XEle = XDOC.CreateElement("IDs");

XEle.SetAttribute("id", Convert.ToString(ID));

RootNode.AppendChild(XEle);

XDOC.Save(System.Web.HttpContext.Current.Server.MapPath("~/XmlFiles/Blog.xml"));(here getting error)

Hello,
I found a piece of code which is (pretty much) identical to yours.
http://csharp.net-tutorials.com/xml/writing-xml-with-the-xmldocument-class/
This means that another thread has blocked the file. Is this on your local machine? If so, just restart the machine and try again. Or you can check in system tray if there are pending iis threads waiting to be disposed.

I think it should be okay if you call .Save method without any parameter. It will automatically update the file it read from.

Hi
Try the below link for xml reading.
http://www.aspdotnet-pools.com/2014/07/read-xml-file-into-dataset-and-populate.html
Insteed of reading as above. Read XML in Data set and you will get detail of header in dataset.
Hear is the code

XmlTextReader xmdatareader = new XmlTextReader("Xml/Country.xml");
DataSet _objdataset = new DataSet();

_objdataset.ReadXml(xmdatareader);

Hi,
I think you are reading from~/XmlFiles/Blog.xml file and writing into the same file while object is holding that file.
Just write to another file or release the file your XDOC object holding.
Hope it helps.
Thanks..

I am not too sure if xdoc.Load method will keep the underlying file locked. Please also check if all your asp.net threads are stopped on your machine.
To be on a safer side, you better read the contents of file as a text (preferably in a separate method, which will return entire text) and then load the text instead of the file.
Please also remember that in real world you will anyway going to face problem if multiple users trigger this function, which is quite common in web scenario.
