Metro中XML文件操作

using System.Xml.Linq;

从文件加载：

file = await KnownFolders.DocumentsLibrary.GetFileAsync("test.xml");using (IRandomAccessStream readStream = await file.OpenAsync(FileAccessMode.Read))                    {                        Stream stream = readStream.AsStreamForRead();                        xDoc = XDocument.Load(stream);                    }

获取元素：

xRoot = xDoc.Root;XElement item1 = xRoot.Element("item1");var = xNode.Element("value1").Value;

增加元素：

newXDoc = new XDocument(new XDeclaration("1.0", "utf-8", "yes")root = new Xelement("Root");newXdoc.Add(root);

保存到文件：

using (IRandomAccessStream stream = await file.OpenAsync(FileAccessMode.ReadWrite))            {                newXDoc.Save(stream.AsStreamForWrite(), SaveOptions.None);            }
