C#实现对象XML序列化的方法
本文实例讲述了C#实现对象XML序列化的方法。分享给大家供大家参考。具体实现方法如下：
usingsystem;
usingsystem.xml;
usingsystem.xml.serialization;
usingsystem.text;
usingsystem.io;
publicclassutil
{
///<summary>
///对象序列化成xmlstring
///</summary>
publicstaticstringxmlserialize<t>(tobj)
{
stringxmlstring=string.empty;
xmlserializerxmlserializer=newxmlserializer(typeof(t));
using(memorystreamms=newmemorystream())
{
xmlserializer.serialize(ms,obj);
xmlstring=encoding.utf8.getstring(ms.toarray());
}
returnxmlstring;
}
///<summary>
///xmlstring反序列化成对象
///</summary>
publicstatictxmldeserialize<t>(stringxmlstring)
{
tt=default(t);
xmlserializerxmlserializer=newxmlserializer(typeof(t));
using(streamxmlstream=newmemorystream(encoding.utf8.getbytes(xmlstring)))
{
using(xmlreaderxmlreader=xmlreader.create(xmlstream))
{
objectobj=xmlserializer.deserialize(xmlreader);
t=(t)obj;
}
}
returnt;
}
}stringwriter,xmlserializer将对象、对象集合序列化为xml格式的字符串,同时描述如何进行反序列化.
