BinaryFormatter.Deserialize

[Igor]

Hi.

While executing BinaryFormatter.Deserialize() I get:
System.InvalidCastException: Specified cast is not valid.
I implemented ISerializable interface. What may be a problem?

Thanks.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

Igor,

While I haven't taken the time to run the code, I can see that there is
nothing in your class that requires custom serialization. All you have to
do is add the Serializable attribute, and your serialization should work
fine. ISerializable only needs to be implemented when there are other
things (besides the fields in your class) that you want to serialize, or
they require certain logic to be executed.

Hope this helps.

do is add the Serializable attribute, and your serialization should

work fine. ISerializable only needs to be implemented when there are other
things (besides the fields in your class) that you want to serialize, or they require certain logic to be executed.

Hope this helps.

[Joep]

application = (ApplicationInfo)formatter.Deserialize((Stream)e.g etDocument);

What tells splitting the above compound statement into a sequence of simple
statements you? What part gives the error? What are the actual types
involved? Make sure you indeed get back what you expect, show us the
splitted version and the real types involved. Sofar I see nothing wrong but
you have an error that pops up in the above line so there must be some
mismatch...

[Igor]

object obj = formatter.Deserialize((MemoryStream)e.getDocument) ;

ApplicationInfo .ApplicationInfo application = (ApplicationInfo.ApplicationInfo)obj;

I get that exception in second row.

In both applications, sender and receiver class defined:
namespace ApplicationInfo

{

[Serializable()]

public class ApplicationInfo:IDisposable

{

...

}
}
