解析XML文件

其中filePath是要读取的xml文件路径

T obj = default(T);
using (IsolatedStorageFileStream istream = new IsolatedStorageFileStream(filePath, FileMode.Open, storageFile))
using (XmlReader reader = XmlReader.Create(istream))
{
　　XmlSerializer serializer = new XmlSerializer(typeof(T));
　　obj = (T)serializer.Deserialize(reader);
}
