本文实例讲述了c#自定义序列化iserializable的实现方法。分享给大家供大家参考。具体实现方法如下：
我要评论
[serializable]
public class baseobject
{
[optionalfield]
private string _str = "i am baseobject";
}
[serializable]
public class testobject : baseobject, iserializable
{
int a;
string strname = "";
color c = color.red;
datatable _dtcolors = null;
[optionalfield]
arraylist list = new arraylist();
[optionalfield]
list<int> list1 = new list<int>();
[optionalfield]
dictionary<int, string> dic = new dictionary<int, string>();
//当实现iserializable接口时，如果该构造函数不存在，则会引发一个serializationexception异常
//该特性表示，该方法只允许序列化器调
[securitypermissionattribute(securityaction.demand, serializationformatter = true)]
protected testobject(serializationinfo info, streamingcontext context)
{
#region 如果基类也实现了iserializable接口，则序列化器会自动调用基类的该构造函数，就不需要本段代码
type basetype = this.gettype().basetype;
memberinfo[] mi = formatterservices.getserializablemembers(basetype, context);
for (int i = 0; i < mi.length; i++)
{
//由于addvalue不能添加重名值，为了避免子类变量名与基类变量名相同，将基类序列化的变量名加上基类类名
fieldinfo fi = (fieldinfo)mi[0];
object objvalue = info.getvalue(basetype.fullname + "+" + fi.name, fi.fieldtype);
fi.setvalue(this, objvalue);
}
#endregion
a = info.getint32("a");
strname = info.getstring("strname");
c = (color)info.getvalue("c", typeof(color));
_dtcolors = (datatable)info.getvalue("_dtcolors", typeof(datatable));
list = (arraylist)info.getvalue("list", typeof(arraylist));
list1 = (list<int>)info.getvalue("list1", typeof(list<int>));
dic = (dictionary<int, string>)info.getvalue("dic", typeof(dictionary<int, string>));
}
public testobject()
{
a = 100;
strname = "daps";
initcolortable();
list1.add(10);
list1.add(20);
}
#region iserializable 成员
[securitypermissionattribute(securityaction.demand, serializationformatter =true)]
void iserializable.getobjectdata(serializationinfo info, streamingcontext context)
{
info.addvalue("a", a);
info.addvalue("strname", strname);
info.addvalue("c", c);
info.addvalue("_dtcolors", _dtcolors);
info.addvalue("list", list);
info.addvalue("list1", list1);
info.addvalue("dic", dic);
type basetype = this.gettype().basetype;
memberinfo[] mi = formatterservices.getserializablemembers(basetype, context);
for (int i = 0; i < mi.length; i++)
{
//由于addvalue不能添加重名值，为了避免子类变量名与基类变量名相同，将基类序列化的变量名加上基类类名
info.addvalue(basetype.fullname + "+" + mi[i].name, ((fieldinfo)mi[i]).getvalue(this));
}
}
#endregion
}
