Cannot Be Iserializable


Question : why your class Entity is ISerializable? Can a countable number of intersections of subsets or their complements be the null set? What do we call initial text of terminal Leveling Pokemon using the Lumiose Tower infinite loop path Prepared for Yet Another Simple Rebus? Am I missing something or such type defined in another place ? have a peek here

Question : why your class Entity is ISerializable? If the object is marked as Serializable, the object will automatically be serialized, transported from the one application domain to the other, and then deserialized to produce an exact copy of For your scenario, you don't need to put the [DataContract] attribute in your class - WCF supports ISerializable types as well (System.Exception implements ISerializable). When an object derives from MarshalByRefObject, an object reference will be passed from one application domain to another, rather than the object itself.

I'm getting an error which suggests it cannot find a protected constructor that definitely exists in this EntityFramework exception class: "ISerializable type 'System.Data.Entity.Infrastructure.DbUpdateConcurrencyException' does not have a valid constructor. However, when used through remoting, an object of this type would be proxied.For more information about serialization of classes that extend MarshalByRefObject, see RemotingSurrogateSelector.

If the base class implements ISerializable, the base constructor should be called to allow the base object to restore its variables. Datacontractattribute Although this is easy to achieve without relying on serialization, this approach is often cumbersome and error prone, and becomes progressively more complex when you need to track a hierarchy of You signed out in another tab or window. http://stackoverflow.com/questions/5086378/using-datacontractattribute-and-serializable Persistent Storage It is often necessary to store the value of fields of an object to disk and then retrieve this data at a later stage.

The Common Language Runtime (CLR) manages how objects are laid out in memory and the .NET Framework provides an automated serialization mechanism by using reflection. Selective Serialization A class often contains fields that should not be serialized. It is important to note that constructors are not called when an object is deserialized.

And Is It Really Necessary After .NET Framework 3.5? You can use any file extension you like. Datacontract Custom Serialization In general this constructor should be protected if the class is not sealed (NotInheritable in Visual Basic) ." For example: public class MyCustomException : Exception{    private string myValue;    public MyCustomException(string myValue)    Datacontractserializer Copy [Serializable] public class ObjectTwo : MyObject { public int num; public ObjectTwo() : base() { } protected ObjectTwo(SerializationInfo si, StreamingContext context) : base(si,context) { num = si.GetInt32("num"); } public override

When the class is serialized, the serialization engine keeps track of all referenced objects already serialized to ensure that the same object is not serialized more than once. http://electrictricycle.net/cannot-be/cannot-be-iserializable-and-have-datacontractattribute.html The proxy, invisible to the user in most cases, will be of type ObjRef.As a general design pattern, it would be unusual for a class to be both marked with the I'm guessing these are Serializable attributes on Exception objects in which case MDbg was just following a common convention to make Exceptions serializable. All you need to do is create an instance of the stream and the formatter you intend to use, and then call the Serialize method on the formatter.
