Store ISeriable Object in ViewState ?

[Sandilian]

I want to store Custom Class object to ViewState for later use Note : I want to use ISeriable interface not [Serializable] property (When i use [Serializable] property, it is working fine but in my case i have to use only ISeriable Interface, I have option to store object into ViewState only not XML or File) PlZ help me. Sample.aspx Person oPerson = new Person(); oPerson.FirstName = "Sandilian"; oPerson.LastName = "Arumugam"; ViewState["Object"] = oPerson; Person cls1 = (Person)ViewState["Object"]; Response.Write(cls1.FirstName + " " + cls1.LastName); Person.CS //[Serializable] public class Person : ISerializable { private string _FirstName; private string _LastName; public string FirstName { get { return _FirstName; } set { _FirstName = value; } } public string LastName { get { return _LastName; } set { _LastName = value; } } public Person() { } public Person(string FirstName, string LastName) { this.FirstName = FirstName; this.LastName = LastName; } public void GetObjectData(SerializationInfo oInfo, StreamingContext oContext) { oInfo.AddValue("FirstName", this.FirstName); oInfo.AddValue("LastName", this.LastName); oInfo.SetType(typeof(Person)); } }

If you want to store it in directly ViewState, it must have the [Serializable] attribute. No other way. What is the problem with using the attribute?

PL do not accept this type of declaration. that is the problem . Can you suggest me some way to solve this problem.
