一个可序列化的C#对象，如何转成一个XML格式的文件或字符串(转)

序列化或反序列化成一个字符串：

方法一：序列化：

public static string XMLSerialize<T(T entity){StringBuilder buffer = new StringBuilder();
XmlSerializer serializer = new XmlSerializer(typeof(T));
using (TextWriter writer = new StringWriter(buffer)){serializer.Serialize(writer, entity);}
return buffer.ToString();}反序列化：
public static T DeXMLSerialize<T(string xmlString){T cloneObject = default(T);
StringBuilder buffer = new StringBuilder();
buffer.Append(xmlString);
XmlSerializer serializer = new XmlSerializer(typeof(T));
using (TextReader reader = new StringReader(buffer.ToString())){Object obj = serializer.Deserialize(reader);
cloneObject = (T)obj;}
return cloneObject;}

方法二：

/// <summary
/// 对象序列化成 XML String
/// </summary
public static string XmlSerialize<T(T obj){string xmlString = string.Empty;
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream()){xmlSerializer.Serialize(ms, obj);
xmlString = Encoding.UTF8.GetString(ms.ToArray());}return xmlString;}
/// <summary
/// XML String 反序列化成对象
/// </summary
public static T XmlDeserialize<T(string xmlString){T t = default(T);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
using (Stream xmlStream = new MemoryStream(Encoding.UTF8.GetBytes(xmlString))){using (XmlReader xmlReader = XmlReader.Create(xmlStream)){Object obj = xmlSerializer.Deserialize(xmlReader);
t = (T)obj;}}return t;}如果要序列化到一个文件，则使用FileStream就可以了如：string strFile = @c:/book.xml;
using (FileStream fs = new FileStream(strFile, FileMode.Create)){
XmlSerializer formatter = new XmlSerializer(typeof(T));
formatter.Serialize(fs, entity);}附：其实还可以直接用SringWriter
StringBuilder sb = new StringBuilder();
System.IO.StringWriter writer = new System.IO.StringWriter(sb);
