Can we hold object in ViewState

[Serializable]
public class Student
{
  public string firstName;
  public string lastName;
 
  public Student(string fName, string lName)
  {
  firstName = fName;
  lastName = lName;
  }
}


Because the Student class is marked as serializable, it can be stored in view state:
// Storing a student in view state.
Student stud = new Student("John", "Doe");
ViewState["CurrentStudent"] = stud;
Remember, when using custom objects, you'll need to cast your data when you retrieve it from view state.
// Retrieve a student from view state.
Student stud = (Student) ViewState["CurrentStudent"];
