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

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);

XmlSerializer formatter = new XmlSerializer(typeof(T));

formatter .Serialize(writer,entity );
