最好不要这么干,cookie是有长度限制的.
一定要的话最好只取关键信息,依据情况序列化成字符串形式(xm/json/querystring)然后就直接存进去就行了,其他的cookie对象会帮你搞定.
querystring注意key和value都要urlencode.
比较保险的做法还是把数据序列化到服务端,再放置一个id之类的东西把客户端和服务器的序列化对象关联起来

protected void Page_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt.Columns.Add("AA");
string str = this.SerializeObject(dt);
Response.Write(str);
object o = this.DeserializeObject(str);
DataTable dt1 = (DataTable)o;
Response.Write("<BR>字段="+dt1.Columns[0].ColumnName);
}
public string SerializeObject(object o)
{
System.Runtime.Serialization.IFormatter obj = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
MemoryStream ms = new MemoryStream();
obj.Serialize(ms, o);
BinaryReader br = new BinaryReader(ms);
ms.Position = 0;
byte[] bs = br.ReadBytes((int)ms.Length);
ms.Close();
return Convert.ToBase64String(bs);
}
public object DeserializeObject(string str)
{
System.Runtime.Serialization.IFormatter obj = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
byte[] bs = Convert.FromBase64String(str);
MemoryStream ms = new MemoryStream();
ms.Write(bs,0,bs.Length);
ms.Position = 0;
object o = obj.Deserialize(ms);
ms.Close();
return o;
}
