首先创建一个Windows Phone 7项目，然后在MainPage.xaml.cs（或其他页面文件）中引入命名空间：

using System.Xml;
using System.IO.IsolatedStorage;
using System.IO;

使用XmlWriter 保存XML文件到隔离存储空间

示例中创建了一个名为People2.xml的XML文件并写入数据。

using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
    using (IsolatedStorageFileStream isoStream = new IsolatedStorageFileStream("People2.xml", FileMode.Create, myIsolatedStorage))
    {
        XmlWriterSettings settings = new XmlWriterSettings();
        settings.Indent = true;
        using (XmlWriter writer = XmlWriter.Create(isoStream, settings))
        {
 
            writer.WriteStartElement("p", "person", "urn:person");
            writer.WriteStartElement("FirstName", "");
            writer.WriteString("Kate");
            writer.WriteEndElement();
            writer.WriteStartElement("LastName", "");
            writer.WriteString("Brown");
            writer.WriteEndElement();
            writer.WriteStartElement("Age", "");
            writer.WriteString("25");
            writer.WriteEndElement();
            // Ends the document
            writer.WriteEndDocument();
            // Write the XML to the file.
            writer.Flush();
        }
    }
}

使用StreamReader从隔离存储空间中读取XML文件

示例中打开了一个已存在的文件People2.xml并读取它的内容。然后把数据显示在一个TextBlock 上。

try
{
    using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
    {
        IsolatedStorageFileStream isoFileStream = myIsolatedStorage.OpenFile("People2.xml", FileMode.Open);
        using (StreamReader reader = new StreamReader(isoFileStream))
        {
            this.tbx.Text = reader.ReadToEnd();
        }
    }
}
catch
{ }
