.net提供了三种序列化方式:
1.XML Serialize
2.Soap Serialize
3.Binary Serialize
第一种序列化方式对有些类型不能够序列化,如hashtable;我主要介绍后两种类型得序列化
一.Soap Serialize
使用SoapFormatter.Serialize()实现序列化.SoapFamatter在System.Runtime.Serialization.Formatters.Soap命名空间下,使用时需要引用System.Runtime.Serialization.Formatters.Soap.dll.它可将对象序列化成xml.
比如要序列化MyClass类
[Serializable]
class MyClass:ISerializable
{
protected string _name;
protected string _id;
protected Hashtable fieldtype=new Hashtable();
public MyClass():base(){ }
public MyClass(SerializationInfo si, StreamingContext context):base(si,context){}
public string Name
{
get
{
return _name;
}
}
public string ID
{
get
{
return _id;
}
}
public Hashtable FieldTypeHash {
get{return this.fieldtype;}
}
public void Start()
{
.........
}
}
在这个类中,红色部分为必须有的.否则在序列化此类的时候会产生异常“必须被标注为可序列化“,“没有构造函数“等...
下面是序列化函数,将对象序列化后转化成string字符串输出
public string SoapSerializer(object o)
{
//FileStream fs = new FileStream("DataFile.xml", FileMode.Create);
Stream ms=new MemoryStream();
// Construct a SoapFormatter and use it to serialize the data to the stream.
SoapFormatter formatter = new SoapFormatter();
try
{
formatter.Serialize(ms, o);
byte[] b=new byte[ms.Length];
ms.Position=0;
ms.Read(b,0,b.Length);
string s=Convert.ToBase64String(b);
return s;
}
catch (SerializationException e)
{
Console.WriteLine("Failed to serialize. Reason: " + e.Message);
throw;
}
finally
{
ms.Close();
}
}
下面是反序列化函数,
public MyClass Deserialize(string returnString)
{
SoapFormatter formatter;
MemoryStream ms=null;
try
{
formatter = new SoapFormatter();
byte[] b=Convert.FromBase64String(returnString);
ms=new MemoryStream(b);
MyClass response = (MyClass ) formatter.Deserialize(ms);
return response;
}
catch (SerializationException e)
{
Console.WriteLine("Failed to deserialize. Reason: " + e.Message);
throw;
}
finally
{
ms.Close();
}
}
二.Binary Serialize和SoapSerialize类似,将SoapFormatter改成BinaryFormatter即可,但要使用System.Runtime.Serialization.Formatters.Binary命名空间.
