BinaryFormatter .Deserialize

Igor

Hi.

While executing BinaryFormatter .Deserialize() I get:
System.InvalidC astException: 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?

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.

Igor,

What is the problem when you have JUST the serializable attribute, and
remove the serialization constructor and the implementation of
ISerializable?

Igor,

What is the problem when you have JUST the serializable attribute, and
remove the serialization constructor and the implementation of
ISerializable?

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.

Any size limitation on the BinaryFormatter serialization

by: Dominic | last post by:

Hi everybody, In my application, I'm planning to use BinaryFormatter to serialize a potentially huge object to file (and, of course, deserialize back to memory later). My question is if there is any hard limit on the size of this object? Is it only limited by the amount of memory or hard-disk space in the server?
