xml序列化与反序列化

　　经常将对象实例序列化为xml文件，将xml反序列化为对象。随写成公共方法供调用。

 1 public static class XmlHelper 2     { 3         /// <summary> 4         /// 将对象保存为xml文件 5         /// </summary> 6         /// <typeparam name="T">对象类型</typeparam> 7         /// <param name="path">保存文件的路径及文件名如“C:/test.xml”</param> 8         /// <param name="obj">要保存对象的实例</param> 9         /// <param name="xmlRootName">跟节点名</param>10         public static void EntitySaveToXml<T>(string path, T obj, string xmlRootName =null )11         {12             if (string.IsNullOrEmpty(path))13             {14                 throw new ArgumentNullException("path 不能为空！");15             }16             if (obj == null){17                 throw new ArgumentNullException("obj 不能为空！");18             }19 20             using (FileStream fs = new FileStream(path, FileMode.Create))21             {22                 var type = typeof(T);23                 var xmlSerializer = string.IsNullOrEmpty(xmlRootName) ? new XmlSerializer(type) : new XmlSerializer(type, xmlRootName);24                 xmlSerializer.Serialize(fs, obj);25                 fs.Close();26                 fs.Dispose();27             }28         }29 30         /// <summary>31         /// 将xml文件发序列化为对象32         /// </summary>33         /// <typeparam name="T">对象类型</typeparam>34         /// <param name="path">xml路径如“C:/test.xml”</param>35         /// <param name="xmlRootName">xml根节点名</param>36         /// <returns>对象实例</returns>37         public static T XmlToEntity<T>(string path, string xmlRootName=null)38         {39             T result;40             if (File.Exists(path))41             {42                 using (StreamReader sr = new StreamReader(path))43                 {44                     var type = typeof(T);45                     var xmlSerializer = string.IsNullOrEmpty(xmlRootName) ? new XmlSerializer(type) : new XmlSerializer(type, xmlRootName);46                     result = (T)xmlSerializer.Deserialize(sr);47                     sr.Close();48                     sr.Dispose();49                 }50             }51             else52             {53                 throw new Exception("文件不存在!");54             }55             return result;56         }57     }
