在C#中，可以用XmlSerializer类来反序列化与序列化xml，但我们也可以封装一下，可以使用起来更方便

  1. 将XML字符串反序列化成对象 方法

    /// <summary>
/// 将XML字符串反序列化成对象
/// </summary>
/// <typeparam name="T">返回的对象类型</typeparam>
/// <typeparam name="xml">xml字符串</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>返回对象类型</returns>
public static T Deserialize<T>(string xml, string xmlRootName = "Root")
{
 T result = default(T);
 using (StringReader sr = new StringReader(xml))
 {
     XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
         new XmlSerializer(typeof(T)) : new XmlSerializer(typeof(T), new XmlRootAttribute(xmlRootName));
     result = (T)xmlSerializer.Deserialize(sr);
 }
 return result;
}

  2. 将XML文件反序列化成对象 方法

    /// <summary>
/// 将XML文件反序列化成对象
/// </summary>
/// <typeparam name="T">返回的对象类型</typeparam>
/// <typeparam name="xml">文件路径</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>返回对象类型</returns>
public static T DeserializeFile<T>(string filePath, string xmlRootName = "Root")
{
 T result = default(T);
 if (File.Exists(filePath))
 {
     using (StreamReader reader = new StreamReader(filePath))
     {
         XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
             new XmlSerializer(typeof(T)) : new XmlSerializer(typeof(T), new XmlRootAttribute(xmlRootName));
         result = (T)xmlSerializer.Deserialize(reader);
     }
 }

 return result;
}

  3. 将对象序列化成XML字符串 方法

    /// <summary>
/// 将对象序列化成XML字符串
/// </summary>
/// <typeparam name="sourceObj">数据对象</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>xml字符串</returns>
public static string Serializer(object sourceObj, string xmlRootName = "Root")
{
 MemoryStream Stream = new MemoryStream();
 Type type = sourceObj.GetType();
 XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
     new XmlSerializer(type) : new XmlSerializer(type, new XmlRootAttribute(xmlRootName));
 xmlSerializer.Serialize(Stream, sourceObj);
 Stream.Position = 0;
 StreamReader sr = new StreamReader(Stream);
 string str = sr.ReadToEnd();
 sr.Dispose();
 Stream.Dispose();

 return str;
}

  4. 将对象序列化成XML文件 方法

    /// <summary>
/// 将对象序列化成XML文件
/// </summary>
/// <typeparam name="filePath">xml文件路径</typeparam>
/// <typeparam name="sourceObj">数据对象</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
public static void SerializerFile(string filePath, object sourceObj, string xmlRootName = "Root")
{
 if (!string.IsNullOrWhiteSpace(filePath) && sourceObj != null)
 {
     Type type = sourceObj.GetType();
     using (StreamWriter writer = new StreamWriter(filePath))
     {
         XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
             new XmlSerializer(type) : new XmlSerializer(type, new XmlRootAttribute(xmlRootName));

         xmlSerializer.Serialize(writer, sourceObj);
     }
 }
}
