C# XmlSerializer的出处：

1. using System.Xml.Serialization; 

C# XmlSerializer实现序列化：

XmlSerializer xml = new XmlSerializer(typeof(Test));  
FileStream fs = new FileStream(@"c:\t.xml",FileMode.Create);  
xml.Serialize(fs, t);  
fs.Close(); 

C# XmlSerializer实现反序列化：

FileStream fs = new FileStream(@"c:\t.xml", FileMode.Open);  
XmlSerializer xml = new XmlSerializer(typeof(Test));  
Test t = (Test)xml.Deserialize(fs)
